Answer:
0.31 g
Explanation:
The equation of the reaction;
HKC8H4O4(aq) + NaOH(aq) ----> Na(KC8H4O4)(aq) + H2O(l)
Number of moles of NaOH = 15/1000 L × 0.1 M
= 0.0015 moles
Since the reaction is 1:1, 0.0015 moles of KHP reacted;
Number of moles of KHP = mass of KHP reacted/molar mass of KHP
Mass of KHP = Number of moles of KHP × molar mass of KHP
Mass of KHP = 0.0015 moles × 204.22 g/mol
Mass of KHP = 0.31 g
It would be the very first response. A. How do atoms combine to form new substances.
Answer : The correct option is B.
Explanation :
The temperature of the warm water is higher than the cold water. That means as the temperature of warm water increases, the kinetic energy of the warm water molecule also increases.
As the kinetic energy of the warm water molecule increases, the number of molecules conversion into a vapor also increases (i.e, quick evaporation), thereby increasing the vapor pressure of warm water.
Hence, the correct answer is, (B) Warm water evaporates more quickly.
Bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.
<h3>What is Bond energy?</h3>
The term bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.
The energy that must be supplied to break the bonds in two molecules of HCl is 862 J. The energy released is obtained from; 862J - [436 +262] = 164J.
The total energy of the reaction is 164J, this is called the enthalpy change. Based on this value of the total energy, the reaction is endothermic. Hence, it is true that; "It takes more energy to break the two H–Cl bonds than is released when forming the H–H and Cl–Cl bonds."
