vfiekz [6]

<span>The boiling point of bromine (br2) is lower than iodine monochloride (icl) because icl molecules have a higher melting point. Also, the atoms of iodine monochloride have more electrons causing the intermolecular forces between iodine forces to be stronger. As the iodine forces are stronger, the boiling point will be higher.</span>

State of matter

Nina [5.8K]

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

<em>Graham's law:</em>

$\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }$

<em>Where V is the speed of the gases and m the molar mass of those:</em>

<em>As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)</em>

$3.98 =\sqrt{\frac{32g/mol}{m_A} }$

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

What molarity is made when 36.5 g HCl is mixed into 250 mL of solution?

Dominik [7]

Answer:

The molarity of the HCl solution is 4M.

Explanation:

$Molarity=\frac{number\:of\:moles}{Volume\:of\:solution\:in\:L}\\ \\The\:volume\:of\:solution=250mL=0.25L\\\\Number\:of\:moles=\frac{weight\:of\:HCl\:in\:solution}{molecular\:weight\:of\:HCl}\\ \\Molecular\:weight\:of\:HCl=36.5g\\\\The\:weight\:of\:HCl\:in\:solution=36.5g\\\\Number\:of\:moles\:of\:HCl=\frac{36.5}{36.5}=1\:mole\\\\The\:molarity\:of\:HCl\:solution=\frac{1}{0.25}=4M$

Hence, the molarity of the HCl solution = 4 M
