Answer:

V = 11.21 L

Explanation:

Given data:

Volume of helium = ?

Number of moles = 0.500 mol

Temperature = 273.15 K

Pressure of gas = 1 atm

Solution:

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

V = nRT/P

V = 0.500 mol ×  0.0821 atm.L/ mol.K  × 273.15 K / 1 atm

V = 11.21 L / 1

V = 11.21 L

devlian [24]

The interaction which will occur when the non sticky tape pieces are turned towards each other is attraction.

<h3>What is Attraction?</h3>

This involves the coming together of objects as a result of a force. When non-sticky sides of the tape are brought towards each other attraction takes place due to the sticky content.

This however wears off after some time thereby making it the most appropriate choice.

If 40.0 g of HCl react with an excess of magnesium metal, what is the theoretical yield of hydrogen?
lyudmila [28]

The balanced reaction is:<span>

Mg (s) + 2HCl (aq) --> MgCl 2 (aq) + H 2 (g) 

We are given the amount hydrochloric acid to be used for the reaction. This will be the starting point of the calculation.

40.0 g HCl ( 1 mol HCl / 36.46 g HCl) (1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>
