in the reaction Mg (s) + 2HCl (aq) -> H2 (g) + MGCl (aq), how many moles of hydrogen gas will be produced from 75.0 millilite

cricket20 [7]

Step One
Find the moles of HCl
C = 1.0 mol/L
V = 75 mL = 75 / 1000 = 0.75 L
Note the concentration is in Liters.

<em>Formula</em>
n = C*V

<em>Solve</em>
n = 1.0 * 0.075
n = 0.075 moles

Step two
Adjust the number of moles of HCl
How every mol of H2 produced, you will require 2 mol of HCl

$\frac{2 mol HCl}{1 mol H_2} = \frac{0.075\text{mol of HCl given}}{x}$

2/1 = 0.075/x Cross multiply
2x = 0.075 Divide by 2
x = 0.075 / 2
x = 0.0375 moles of H2 <<<<<<<<< Answer

Which statement best describes London dispersion forces?

kupik [55]

London force:

London force is an intermolecular force which occurs between an atoms or molecules which are polar or non-polar and another atom or molecule which are polar or non-polar. Hence it occurs between all molecules or atoms. The London dispersion force is a temporary attractive force which cause due to temporary dipoles of electrons in two adjacent atoms. This is also known as induced dipole-induced dipole attraction. It is a weakest Intermolecular force.

therefore the correct answer is D.

attractive inter molecular forces
