I think the answer is 10g
when you freeze a specific amount of water into an ice cube, only the form and the density is changed, while the mass will be pretty much the same.
Probably the mass of the melted water will be a little bit less than the cube (if count the mass that released to the air) , but the amount will NOT BE SIGNIFICANT.
Answer:
86% is the percent yield of the reaction
Explanation:
Percent yield is defined as 100 times the ratio of actual yield / theoretical yield.
Based on the reaction:
2Na + Cl₂ → 2NaCl
The theoretical yield is 0.50 moles because 0.50 mol of Na are added in the beginning. As 0.43 moles are produced, actual yield is 0.43 mol. And percent yield is:
0.43mol / 0.50mol * 100 =
<h3>86% is the percent yield of the reaction</h3>
The answer to the question
stated above is:
<span> Gas is easily compressible because the molecules of a gas are much further apart than
those of a solid.</span>
characteristic properties of gases:
(1) they are easy to compress,
(2) they expand to fill their containers, and
(3) they occupy far more space than the liquids or solids
from which they form.
