Answer:

When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.

Answer:

We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.

Answer:

We can measure volumes approaching absolute zero and then predict what the volume would be at absolute zero.

Since there is NO molecular motion at absolute zero, the volume of a balloon at absolute zero should be zero.

If you headed to the deepest recesses of intergalactic space, shielded from starlight, the only thing that would heat you up would be the Big Bang's leftover glow: the cosmic microwave background at 2olume.ht v725 K.   At that temperature, the balloon would have a volume.

          Charles' Law asserts that a gas's volume (V) and temperature (T), which must be expressed in Kelvin, are directly proportional to one another. A change in temperature of one Kelvin unit corresponds to a change in one Celsius degree. Never forget that the value 0 on the Kelvin scale corresponds to -273 or "Absolute Zero."

          Charles's Law, V = a T+ b, is used to calculate absolute zero once the mass measurements are transformed to high and low temperature gas volumes.

         The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion. Actually, above this temperature, all gases condense into solids or liquids.

           According to Boyle's Law, gas volume grows as pressure lowers. Charles' Law states that when the temperature rises, the volume of the gas increases.

          Gases compress infinitely as the temperature is lowered because there is a linear relationship between temperature and pressure for the majority of gases (see gas laws). The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion.

The characteristics of the reactivity of the periodic table allows to find the correct answers to the different questions are:

1) Metals on the right have more protons, causing valence electrons to be held more strongly.

2) They are very nonreactive.

3) Na and Br

4) Rb loses an electron

1) The reactivity of a chemical element is the tendency to combine with others, this increases as it has fewer electrons in its last layer and since they are more weakly bonded.

Consequently, halogens have seven electrons in their last shell tends to attract an electron to remain with the full level and the alkaline that an electron has in the last shell tends to lose the electron to remain with a complete shell.

If we examine the periodic table the number of electrons in the last shell decreases from right to left.

Let's review the different claims:

a) False. The elements on the right side have a higher atomic number, therefore more protons.

b) True. The elements have more protons therefore it has to attract other electrons and the reactivity decreases.

c) False. As it has more electrons, it has more energy levels, losing all the electrooens is more difficult, so the reactivity decreases.

d) False. By having more electrons it has more energy levels.

2) What is the unique characteristic of the elements of group 18

The elements of group 18 are the noble gases, they have their last full layer therefore they do not have.

the correct answer is:  They are very nonreactive.

3) The reactivity in the period table decreases with increasing period therefore the element of period 3 is the most reactive in this case Sodium and Halogen of group 5 is the most reactive in this case Bromine.

the compound Na and Br is the most reactive of all.

4) Rubidium has 1 electron in its last shell, both in a chemical reaction pole loses the electron.

the correct answer is: Rb loses an electron

In conclusion, using the characteristics of the reactivity of the periodic table, we can answer the different questions..

      1) Metals on the right have more protons, causing valence electrons to be held more strongly.

      2) They are very nonreactive.

      3) Na and Br

The amount of Mg(OH)2  present after the reaction is complete is 0.136 moles of Mg(OH)2.

The equation of the reaction is;

2HNO3(aq) + Mg(OH)2(aq) -------> Mg(NO3)2(aq) + 2H2O(l)

Number of moles of Mg(OH)2 = 8.00 g/58 g/mol = 0.138 moles

Number of moles of HNO3 = 0.205 M × 24.2 mL/1000 = 0.00496 moles

Given that;

2 moles of HNO3 reacts with 1 mole of Mg(OH)2

0.00496 moles of HNO3 reacts with 0.00496 moles ×  1 mole /2 moles = 0.00248 moles of Mg(OH)2

Hence, Mg(OH)2 is the reactant in excess.

The amount of Mg(OH)2 remaining = Amount present - Amount reacted

Hence; 0.138 moles - 0.00248 moles = 0.136 moles of Mg(OH)2

Greenhouse gases such as N2O, CO2 and CH4 absorb heat. However, CH4 absorbs more heat than CO2 hence its emission must be controlled.

Green house gases are gases that when released into the atmosphere, can absorb infrared radiation and prevent it from escaping into outer space. This causes the temperature of the earth to increase steadily. Lately, the concentration of the greenhouse gases in the atmosphere has increased owing to anthropogenic activities such as burning of fossil fuels.

Green house gases include; N2O, CO2, CH4 etc. However, CH4 is capable of absorbing even greater heat than CO2. This makes it even more imperative to control the emission of methane gas.

Advantages of Genetic Engineering?

1. It allows for a faster growth rate.

2. It can create an extended life.

3. Specific traits can be developed.

Plants and animals can have specific traits developed through genetic engineering that can make them more attractive to use or consumption. Different colors can be created to produce a wider range of produce. Animals can be modified to produce more milk, grow more muscle tissue, or produce different coats so that a wider range of fabrics can be created.

4. New products can be created.

5. Greater yields can be produced.

Genetic engineering can also change the traits of plants or animals so that they produce greater yields per plant. More fruits can be produced per tree, which creates a greater food supply and more profits for a farmer. It also creates the potential for using modified organisms in multiple ways because there is a greater yield available. Modified corn, for example, can be used for specific purposes, such as animal feed, ethanol, or larger cobs for human consumption.

6. Risks to the local water supply are reduced.

Because farmers and growers do not need to apply as many pesticides or herbicides to their croplands due to genetic engineering, fewer applications to the soil need to occur. This protects the local watershed and reduces the risk of an adverse event occurring without risking the yield and profitability that is needed.

7. It is a scientific practice that has been in place for millennia.

Humans in the past may not have been able to directly modify the DNA of a plant or animal in a laboratory, but they still practiced genetic engineering through selective breeding and cross-species or cross-breeding. People would identify specific traits, seek out other plants or animals that had similar traits, and then breed them together to create a specific result. Genetic engineering just speeds up this process and can predict an outcome with greater regularity.

What Are the Disadvantages of Genetic Engineering?

1. The nutritional value of foods can be less.

When animals grow, and mature quickly, the nutritional value of that product can be reduced. This can be seen in poultry products today with the white striping that is found in meat products. That striping is a fat deposit that was created, often in the breast meat, because of the rapid growth of the bird. In chickens, Good Housekeeping reports that this can increase the fat content of the meat consumed by over 220%. At the same time, the amount of protein that is received is also reduced.

2. Pathogens adapt to the new genetic profiles.

Genetic engineering can create a natural resistance against certain pathogens for plants and animals, but the natural evolutionary process is geared toward creating pathways. Bacteria and viruses evolve a resistance to the resistance that is created by the genetic engineering efforts. This causes the pathogens to become stronger and more resistant than they normally would be, potentially creating future health concerns that are unforeseen.

3. There can be negative side effects that are unexpected.

Genetic engineering is guaranteed to make a change. Many of those changes are positive, creating more and healthier foods. Some of those changes, however, can be negative and unexpected. Making a plant become more tolerant to drought might also make that plant become less tolerant to direct sunlight. Animals may be modified to produce more milk, but have a shortened lifespan at the same time so farmers suffer a greater livestock.

4. The amount of diversity developed can be less favorable.

At some point, genetically engineered plants and animals make it “into the wild” and interact with domestic species. This results in a crossing of “natural” and “artificial” organisms. The engineered organisms often dominate, resulting in only a modified species over several generations, reducing the diversity that is available.

5. Copyrighted genetic engineering can have costly consequences.

Many companies copyright their genetic engineering processes or products to maintain their profitability. If a farmer plants genetically modified crops and the pollination process causes another farmer in the field over to have those modified crops grow, there have been precedents for legal actions against the “unauthorized” farmer. This can have several costly consequences, from fewer farmers wanting to work to a higher cost for the seeds that are planted.

6. This knowledge and technology can be easily abused.

At the moment, genetic engineering in humans is being used to treat specific disorders that threaten the health or wellbeing of individuals. In time, the approach in humans could be like what is already being done with plants and animals. Genetic engineering can change specific traits, which could create human outcomes that are ethically questionable or easily abused.
