How many grams and what is the limiting reactent?
gayaneshka [121]
Hello!

1) What is the limiting reactant?

The chemical equation for this reaction is:

2Al(OH)₃ → Al₂O₃ + 3H₂O

The Limiting Reactant is the one that is in the lowest amount in the reaction and determines how many moles are produced. You can see that in this chemical equation there is only one reactant since this reaction is a decomposition reaction. So, the limiting reactant is Al(OH)₃.

2) How many grams of water are produced?

The chemical equation for this reaction is:

2Al(OH)₃ → Al₂O₃ + 3H₂O

So, we are going to use the following conversion factor to go from grams of Al(OH)₃ to grams of water:

17,8 g Al(OH)_3* \frac{1 mol Al(OH)_3}{78 g Al(OH)_3}* \frac{3 moles H_2O}{2 moles Al(OH)_3}* \frac{18,015 g H_2O}{1 mol H_2O} \\ =6,17 g H_2O

So, 6,17 grams of Water are produced.

Have a nice day!

A gas occupies a volume of 410 mL at 27°C and 740 mm Hg pressure. Calculate the volume the gas
murzikaleks [220]

Answer:

The volume of gas is 58.22 L which will occupy at 250.°C and 680 mm Hg pressure.

Explanation:

Given:

Temperature = 27°C

To make it into kelvin   = 27+273

 = 300K

Pressure  =740mm Hg

to make it in atm.  = \frac{740}{760}

= 0.973atm

n   = 2.3 moles

Volume of gas =?

 As we know according to the formula

 PV   = nRT

V= \frac{nRT}{P}

On substituting the values

 = \frac{2.3\times0.0827\times300}{0.973}

= 58.22 L

Therefore, 58.22L volume of gas will occupy at 250.°C and 680 mm Hg pressure.
