Answer:
a) 26.98
b) 3
c) 3* 1.01 = 3.03
d) 3 *16 = 48
e) 26.98 + 3.03 + 48 = 78.01
f) 6.023 * 10²³
The answer the following are as follows:
<span> 1. XeF4 - molecules are polar

5. CH3Br - molecules are non-polar
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
Answer:
What are the statements please
Explanation:
1) Write the balaced chemical equation:
H2 + 2O2 → 2H2O
2) Infere the molar ratios:
1 mol H2 : 2 mol of water
3) Make the calculus as the direct proportion relation:
[2 mol H2O] / [1 mol H2] * 7 mol H2 = 14 mol H2
As you see you produce the double number of moles of H2O than number of moles of H2 used.
Answer: 14 moles
