When methane (CH4) combines with oxygen (O2), carbon
dioxide (CO2) and water vapor (H20) are produced.
Which equation represents this chemical reaction?
O A. CO2 + CH4 + 2H20 + 202
OB. CO2 + 2H20 – 202 + CH4
OC. CH4 + 202 – CO2 + 2H20
OD. CH4 + 2H20 - 202 + CO2

Answers

Answer 1

Answer:

C. CH4 + 202 – CO2 + 2H20

Explanation:

CH4+O2-CO2+H20

The above equation represents combustion of methane to produce carbon-dioxide and water.

One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side  and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.

The balanced chemical equation is:

CH4+202-CO2+2H2O

This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.

Answer 2

Answer:

C. CH4 + 202 – CO2 + 2H20

Answers

Answer:

Explain how kinetic energy affects each object as it changes its state of matter:

A) Water boiling:

B) Popsicle freezing:

C) Water condensing on the side of a water bottle:

Explanation:

A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.

B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.

C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.

Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

What is Kinetic energy?

A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly.  Because water is condensing as it transforms into a liquid.

Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.

Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.

Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

what will happen to a population of organisms that are in an oxygen rich environment. (Double click the story board to draw on it)​

Answers

Answer

I'll assume this means adding additional oxygen to the atmosphere.

Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.

Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)

Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.

Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)

Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.

We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)

We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

what are the functions of the kidney

Answers

Basic Functions
The kidneys are essential for homeostasis (maintaining a constant internal environment) of the body's extracellular fluids. Their basic functions include:
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.

3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

4. Regulation of pH. The kidneys prevent blood plasma from becoming too acidic or basic by regulating ions.

5. Excretion of wastes and toxins. The kidneys filter out a variety of water-soluble waste products and environmental toxins into the urine for excretion.

6. Production of hormones. The kidneys produce erthryopoietin, which stimulates red blood cell synthesis, and renin, which helps control salt and water balance and blood pressure. They are also involved in regulating plasma calcium and glucose levels.

what is the ultimate source of electrons for photosynthesis in plants?

Answers

Answer: Water

Explanation:

What is the ultimate source of electrons for photosynthesis?

In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH

Photosynthesis is a plant process to make food and energy. It includes various steps to release energy. The water molecule is the ultimate electron donor in the process.

What is photosynthesis?

Photosynthesis is said to be the process that converts solar energy into the chemicals that are used as the energy source in cellular respiration activities. Here, sunlight, carbon dioxide, and water act as reactants.

The carbon dioxide and water undergo splitting by the membrane pigments and then the electron produced from water is carried with enzymes to make NADP⁺. This is further used to make NADPH. As result oxygen along with the sugar molecules are produced and are rich in ATP.

Therefore, water is the foremost source of electrons for photosynthesis in plants.

[ Read the passage now]---> Except from James Polk's 1845 Inaugural Address: Eighty years ago population was confined on the west by the ridge of the Alleghenies. Within that period... our people... have filled the eastern valley of the Mississippi, adventurously ascended the Missouri to its headsprings, and are already engaged in establishing the blessings of self-government in valleys of which the rivers flow to the pacific. The world beholds the peaceful triumphs of the industry of our emigrants. To us belongs the duty of protecting them adequately wherever they may be upon our soil. U.S. Army Officer, Regarding the April 24, 1847, Skirmish Between Mexican and American Forces. We have not one particle of right to be here. It looks as if the government sent a small force on purpose to bring a war, so as to have a pretext for taking California and as much of this country as it chooses. Excerpts from Polk's Message to congress, May 11, 1846: The existing state of the relations between the United States and Mexico renders it proper that I should bring the subject to the consideration of Congress. The strong desire to establish peace with Mexico on liberal and honorable terms, and the readiness of this Government to regulate and adjust our boundary and other causes of difference with that power on such fair and equitable principles as would lead to permanent relations of the most friendly nature. The Mexican Government not only refused to receive him [ the U.S. envoy] or listen to his propositions, but after a long-continued series of menaces have at last invaded our territory and shed the blood of our fellow-citizens on our own soil. I had ordered an efficient military force to take a position between the Nueces and the Del Norte. This had become necessary to meet a threatened invasion of Texas by the Mexican forces. The invasion was threatened solely because Texas had determined, in accordance with a solemn resolution of the Congress of the United States, to annex herself to our Union, and under these circumstances it was plainly our duty to extend our protection over her citizens and soil. Texas, by the final action of our Congress, had become an integral part of our Union. The Congress of Texas, by its act of December 19, 1836, had declared the Rio del Norte to be the boundary of that Republic. Our own Congress had, moreover, with great unanimity, by the act approved December 31, 1845, recognized the country beyond the Nueces as a part of our territory. Accordingly, on the 13th of January last instructions were issued to the general in command of these troops to occupy the left bank of the Del Norte. This river, which is the southwestern boundary of the State of Texas, is an exposed frontier. The Army moved from Corpus Christi on the 11th of March, and on the 28th of that month arrived on the left bank of the Del Norte opposite to Matamoras, where it encamped on a commanding position, which has since been strengthened by the erection of fieldworks. General Ampudia... notified General Taylor to break up his camp within twenty-four hours and to retire beyond the Nueces River, and in the event of his failure to comply with these demands announced that arms, and arms alone, must decide the question. A party of dragoons of 63 men and officers were... dispatched from the American camp up the Rio del Norte, on its left bank. to ascertain whether the Mexican troops had crossed or were preparing to cross the river, became engaged with a large body of these troops, and after a short affair, in which some 16 were killed and wounded, appear to have been surrounded and compelled to surrender. The grievous wrongs perpetrated by Mexico upon our citizens throughout a long period of years remain unredressed, and solemn treaties pledging her public faith for this redness have been disregarded. Mexico has repeatedly threatened to make war upon us for the purpose of reconquering Texas. In the meantime we have tried every effort at reconciliation.
