WHAT MASS OF WATER WILL BE PRODUCED FROM 2.70 MOLES OF CA(OH)2 REACTING WITH HCI

Keith_Richards [23]

Answer: The mass of water produced in the reaction is 97.2 grams

Explanation:

We are given:

Moles of calcium hydroxide = 2.70 moles

The chemical equation for the reaction of calcium hydroxide and HCl follows:

$Ca(OH)_2+HCl\rightarrow CaCl_2+2H_2O$

By Stoichiometry of the reaction:

1 mole of calcium hydroxide produces 2 moles of water

So, 2.70 moles of calcium hydroxide will produce = $\frac{2}{1}\times 2.70=5.40mol$ of HCl

To calculate mass for given number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Molar mass of water = 18 g/mol

Moles of water = 5.40 moles

Putting values in above equation, we get:

$5.40mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=(5.40mol\times 18g/mol)=97.2g$

Hence, the mass of water produced in the reaction is 97.2 grams

A balloon with volume of 2.0l is filled with gas at 3 atmosphere. If the pressure were reduced to 0.5 atmosphere without the cha

solong [7]

Answer: 12L

Explanation:

To find the correct volume of the balloon, we can use the mathematical representation of Boyle’s law which states that a gas’s volume is inversely proportional to its pressure (as one increases the other decreases).

The equation for it is P1 * V1 = P2 * V2 where P1 and V1 represent the initial pressure and volume of the gas and P2 and V2 represent its changed temperature and volume.

In this case, the initial pressure of the gas inside the balloon is 3atm while its initial volume is 2.0L. Its pressure is then reduced to 0.5atm.

If we apply this information to the equation for Boyle’s law, we get
2L * 3atm = 0.5atm * V2.

Through arithmetic, we find that
6 = 0.5atm * V2
6/0.5atm = V2
12L = V2.

So, the volume of the balloon is 12L.

Hope this helps!
