Answer: There are 6.9 mol of
are required to react completely with 2.30 mol of S.
Explanation:
The given reaction equation is as follows.

Here, 1 mole of S is reaction with 3 moles of
which means 1 mole of S requires 3 moles of
.
Therefore, moles of
required to react completely with 2.30 moles S are calculated as follows.

Thus, we can conclude that there are 6.9 mol of
are required to react completely with 2.30 mol of S.
Answer:
3.68 grams.
Explanation:
First we <u>convert 9.5 g of NaCl into moles of NaCl</u>, using its<em> molar mass</em>:
9.5 g ÷ 58.44 g/mol = 0.16 mol NaCl
In<em> 0.16 moles of NaCl there are 0.16 moles of sodium </em>as well.
We now <u>convert 0.16 moles of sodium into grams</u>, using <em>sodium's molar mass</em>:
0.16 mol * 23 g/mol = 3.68 g
Answer:
Dissolving ice tea mix in water is a chemical change
Explanation:
It is a chemical change because you can not bring back the ice tea mix back if you mix it in water.

What i would say: The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
