Answer:
tempature of the person, check carbon levels in the house or place where the person is.
Explanation:
Answer:
5.63 mol.
Explanation:
- The balanced chemical equation between NO₂ and H₂O is:
<em>3NO₂(s) + H₂O(l) → 2HNO₃(aq) + NO(g),
</em>
It is clear that 3 mol of NO₂ reacts with 1 mol of H₂O to produce 2 mol of HNO₃ and 1 mol of NO.
<em>Water is present as an excess reactant and NO₂ is limiting reactant.</em>
<em></em>
- To find the no. of moles of HNO₃ produced:
3 mol of NO₂ produces → 2 mol of HNO₃, from stichiometry.
8.44 mol of NO₂ produces → ??? mol of HNO₃.
∴ The no. of moles of HNO₃ are formed = (8.44 mol)(2 mol)/(3 mol) = 5.63 mol.
From the calculation, the moles of water produced is 18 moles of water.
<h3>What is a decomposition reaction?</h3>
A decomposition reaction is one in which a substance is split up into smaller parts.
We have the reaction; 2 Cr(OH)3(aq) ------------> Cr2O3(s) + 3H2O(l)
From this reaction;
2 moles of Cr(OH)3 produced 3 moles of water
12 moles of Cr(OH)3 will produce;
12 moles * 3 moles / 2moles
= 18 moles of water
Hence, 12 moles of chromium (III) hydroxide produces 18 moles of water.
