Inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
True
False
Answer:
[tex]{ \underline{ \sf{true}}}[/tex]
Explanation:
because they chemically decompose
It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
What are inorganic compounds?Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.
When carbon is bound to hydrogen, the compound is classified as organic.
Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.
Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).
Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.
Thus, the given statement is true.

Explanation:
Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers.use

An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone.
True
False
Answer:
The answer is true.. it is attached to the carbon backbone.
The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.
What is Unsaturated fat?Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.
An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.
Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.
Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

What would happen to a plant if the chloroplasts in its cells became damaged?
Answer:
The plant would die.
Explanation:
The plant's chloroplasts are the organelles that do photosynthesis. They provide sugar (food/energy) for the plant. Without this food, the plant can't carry out other functions like growing and reproducing. Just like any other organism, the plant will die once it runs out of energy.

Carbon dioxide
Glucose
Energy
Water
Answer:
Glucose
Explanation:
In the process of cellular respiration, glucose and oxygen combines to produce products such as carbon dioxide and water.
Reactant+ Reactant= Product.
Glucose (Reactant)+ Oxygen (Reactant)= Carbon Dioxide (Product) and Water (Product) (C02)
Hope this helps!
The one that is a reactant during cellular respiration is Glucose. The correct option is B.
What is cellular respiration?Cellular respiration is a process of breakdown of food material to produce energy that is then saved in the form of ATP. The process occurs when oxygen is combined with food and produces energy and reduces the waste material removed from the body.
The chemical process includes four processes that occur in sequence to carry out the whole process. The processes are glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
All food that we eat gives us different macromolecules, glucose is the main source of energy. So glucose is converted into energy.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?
A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.
Answer:
Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.
Explanation:
Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone.

Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.
Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.
