How many moles of calcium chloride are contained in a 333 gram sample?

Chemistry
1 answer:
Bogdan [553]3 years ago
6 0

Answer & Explanation:

The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..

\frac{333 g(CaCl2)}{} *\frac{1mol(CaCl2)}{110.98g(CaCl2)}

Multiply straight across on the top and straight across on the bottom.

\frac{333}{110.98}

Now divide.

\frac{333}{110.98}=3.00

So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.

Given the balanced equation representing a reaction: H2 → H + H What occurs during this reaction? 1. Energy is absorbed as bonds
RoseWind [281]

Answer : The correct option is, (2) Energy is absorbed as bonds are broken.

Explanation :

As we know that the bonds are formed and breaks during the chemical reaction. Some energy is released or absorbed when the bonds are formed and breaks during the chemical reaction.

During the bond breaking, some energy is required to break the bonds.

During the bond formation, some energy is released to the formation of the bonds.

In the given reaction, the bond between the hydrogen-hydrogen in H_2 are breaking into two hydrogen. That means during the bond breaking, some energy is required or absorbed to break the bonds.

Hence, the correct option is, (2) Energy is absorbed as bonds are broken.
