If you have 9 moles of hydrogen gas(H2) the moles of water that can be formed is 9 moles
<u><em>calculation</em></u>
2H2 +O2→ 2H2O
The mole of H2O is calculated using the mole ratio.
that is H2:H2O is 2:2 into simple form = 1:1
therefore if 9 moles of H2 reacted the moles of H2O = 9 x1/1 = 9 moles
The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.
Answer: CaCO3 reaction.
Explanation: CaO and combine together to result in the formation of calcium carbonate compound. we know it is a synthesis reaction.so we can conclude that the most likely products of Cao + co2 → CaCO3 reaction.
