Answer:
increase
Explanation:
Let's suppose we have a sample of air in a closed container. We heat the container and we want to predict what would happen to the pressure.
According to Gay-Lussac's law, the pressure of a gas is directly proportional to its absolute temperature.
Thus, if we increased the temperature of the air by heating it, its pressure would increase.
If a sample of air in a closed container was heated, the total pressure of the air would increase.
Answer:
1.
Explanation:
Hello,
In this case, for the given reaction we first assign the oxidation state for each species:

Whereas the half reactions are:

Next, we exchange the transferred electrons:

Afterwards, we add them to obtain:

By adding and subtracting common terms we obtain:

Finally, by removing the oxidation states we have:

Therefore, the smallest whole-number coefficient for Sn is 1.

A scientific model is a simplified version of some phenomenon that takes place in natural systems. A scientific model can be visual (flow charts), graphical, conceptual, or mathematical. These models are used to make predictions about how a set of conditions would change the present scenario in future. Scientific models can explain how the ongoing changes in the environment can show long term affect on our planet like the climate change. Therefore, a scientific model can be used to explain the phenomena like the effect of global air temperatures on the mean sea level around the world.
Answer:
0.79 g
Explanation:
Let's introduce a strategy needed to solve any similar problem like this:
- Apply the mass conservation law (assuming that this reaction goes 100 % to completion): the total mass of the reactants should be equal to the total mass of the products.
Based on the mass conservation law, we need to identify the reactants first. Our only reactant is sodium bicarbonate, so the total mass of the reactants is:

We have two products formed, sodium carbonate and carbonic acid. This implies that the total mass of the products is:

Apply the law of mass conservation:

Substitute the given variables:

Rearrange for the mass of carbonic acid:

Answer:
<u>Frederich Miescher</u>- first person to isolate DNA and RNA
<u>Frederick Griffith</u>- first to demonstrate horizontal transmission of dna using bacteria
<u>Gregor Mendel</u>- documented and demonstrated inheritance patterns
Thomas Hunt Morgan- identified chromosomes as the structures responsible for inheritance
<u>Joachim Hammerling</u>- demonstrated that the hereditary information of of eukaryotes is contained within the nucleus
<u>Alfred Hershey and Martha Chase</u>- demonstrated that dna not protein was the molecule responsible for hereditary
<u>George Beadle and Edward Tatum</u>- used mutants to show the relationship between DNA and proteins
<u>Albrecht Kossel</u>- characterized the structure of adenine, guanine, cytosine, thymine, and uracil
