NaOH + HCl => NaCl + H2O
1 mol of NaOH react with 1 mol of HCL
The molecular mass of NaOH is 39.997
The molecular mass of HCl is 36.46
Moles of HCl
=18.73/36.46
=0.5137
Mole of NaOH
=23.26/39.997
=0.5815
moles of NaOH >moles of HCl
so there are not enough HCl
the answer is HCl
Answer:
each continent shifts 2-5 inches per year so once it was joined then it is what it is now.In a million years again it will comes closer and wjo knows what will happen.moutains will be formed as the tectonic plates will collide.
Answer:
No it is not a good conductor
Explanation:
Krypton is classified as a gas and nonmetal. Like many nonmetals and gases, krypton is an insulator, so it is a relatively poor conductor of heat and electricity.
Answer:
ΔH = -22 kcal
Step-by-step explanation:
N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + 22 000 cal
Energy is on the right-hand side of the equation, so it is being <em>released</em> by the system.
The thermodynamic convention is that <em>energy going out of a system is negative.</em> Thus,
ΔH = -22 000 cal Convert to kilocalories
ΔH = -22 kcal
A and B are both wrong, because you divide by 1000 to convert calories to kilocalories.
C is wrong, because the sign must be negative for an exothermic reaction.
