Answer:

65.38 g/mol

Explanation:

The molar mass of a given substance is a physical property defined as its mass (g) per unit amount of substance (mol)

The molar mass of the elements is constant value and is tabulated in the periodic table, where we can find the molar mass of all known elements.

To know what the value of the molar mass of zinc is, we look for this element in the periodic table and find that its molar mass is approximately 65.38g/mol

Answer:

High activation energy is the reason behind unsuccessful reaction.

Explanation:

There are two types of reaction: (1) thermodynamically controlled reaction and (2) kinetically controlled reaction.

Thermodynamically controlled reaction are associated with change in enthalpy during reaction. More negative the enthalpy change, more favored will be the reaction.

Kinetically controlled reaction are associated with activation energy of a reaction. The lower the activation energy value, the more rapid will be the reaction.

Here, reaction between $CCl_{4}$ and $H_{2}O$ is thermodynamically favored due to negative enthalpy change but the high activation energy does not allow the reaction to take place by simple mixing.
