Answer:

option C = all elements are balanced

Explanation:

In given chemical equation all elements are balanced.

Chemical equation:

MgO + 2LiCl → MgCl₂ + Li₂O

This is balanced chemical equation. We can see that there are one Mg atom and one oxygen atom is present in reactant side and also in product side. So, both are balanced.

In case of lithium there are two Li atoms in reactant side and also in product side , it is also balanced.

There are two chlorine atoms are present in reactant side and also in product side. Chlorine atoms are balanced.

What is the molar mass of 81.50 g of gas

garik1379 [7]

The molar mass of gas = 238.29 g/mol

<h3>Further explanation</h3>

Given

mass = 81.5 g

P=1.75 atm

V=4.92 L

T=307 K

Required

molar mass

Solution

The gas equation can be written

$\large{\boxed{\bold{PV=nRT}}$

$\tt n=\dfrac{mass}{molar~mass}$

So the equation becomes :

$\tt Molar~mass=\dfrac{mRT}{PV}$

Input the value :

$\tt M=\dfrac{81.5\times 0.082\times 307}{1.75\times 4.92}\\\\M=238.29~g/mol$

Which of these oxides will likely form a colored solution when dissolved in water?

Alik [6]

Mn₂O

Explanation:

The oxide that will most likely form colored solutions is Mn₂O.

This is because most transition metals form colored compounds. Manganese is a transition metal belonging to the d-block on the periodic table.

Other examples of transition metals are scandium, titanium, iron, copper, cobalt, nickel, zinc
They belong to the d-block on the periodic table.
They have variable oxidation states.
Most of their solutions are always colored.
