vichka [17]3 years ago
7 0

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
