leaves change carbon dioxide and water into A.sugar and oxygen B.soil and sugar C.oxygen and sunlight D. none of the above

Hey there! :D

During the process of photosynthesis, leaves turn carbon dioxide and water into glucose and oxygen. (glucose is just a fancy word for sugar)

So "A" is correct.

We need trees to make oxygen as a waste, or product, of the reaction. Similarly, we take in oxygen and breathe out carbon dioxide. As a cycle.

I hope this helps!

A container is filled with helium gas. It has a volume of 2.25 liters and contains 9.00 moles of helium. How many moles of heliu

Darina [25.2K]

Answer: There are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.

Explanation:

Given: $V_{1}$ = 2.25 L, $n_{1}$ = 9.0 mol

$V_{2}$ = 1.85 L, $n_{2}$ = ?

Formula used to calculate the moles of helium are as follows.

$\frac{V_{1}}{n_{1}} = \frac{V_{2}}{n_{2}}\\$

Substitute the values into above formula as follows.

$\frac{V_{1}}{n_{1}} = \frac{V_{2}}{n_{2}}\\\frac{2.25 L}{9.0 mol} = \frac{1.85 L}{n_{2}}\\n_{2} = \frac{1.85 L \times 9.0 mol}{2.25 L}\\= 7.4 mol$

Thus, we can conclude that there are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.

Which of the following is a change from a more condensed to a less condensed state of matter? Freezing Condensing Evaporating So

3241004551 [841]

Evaporating.

This is because evaporation occurs for things such as water coming in contact with a heat source that cause molecules to run crazy and begin to go farther and farther apart, becoming steam and evaporation in the air.

Therefore, during the process of evaporation, molecules become less condensed.

Hope this helps!

How many moles of HCl are present in 4.7 L of a 4.23 M HCl solution?

REY [17]

Hey There!

Volume = 4.7 L

Molarity = 4.23 M

Therefore:

n = M *V

n = 4.23 * 4.7

n = 19.881 moles of HCl

hope this helps!
