The correct answer is <span>a. CaO(s) + H2O(l) Ca(OH)2 (s)
</span><span>Decreasing in entropy means that you have to get a solid from the liquid
</span>therefore : <span>CaO(s) + H2O(l) Ca(OH)2 (s)
This formula will make it absolutely clear

Answer:
4
Explanation: on the left side of the equation there are 4 carbons, to make 4 carbons on the right side of the equation you need 4 of the CO2 molecules.
Answer: 1 molecule of 
reacts with 1 molecule of 
to give 2 molecules of HCl.
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Explanation:
The given balanced reaction is:
On the particulate level :
1 molecule of reacts with 1 molecule of to give 2 molecules of HCl.
On molar level:
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Hey there!:
Density = 0.798 g/mL
Volume = 16.9 mL
Therefore:
Mass = density * volume
Mass = 0.798 * 16.9
Mass = 13.4862 g
