Nitrogen is more reactive than oxygen and oxygen than chlorine
Answer:
<h3>The answer is 756 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of silver = 72 cm³
density = 10.5 g/cm³
We have
mass = 10.5 × 72
We have the final answer as
<h3>756 g</h3>
Hope this helps you

Methane in fuel cells are not burned and therefore, help to reduce pollutants commonly associated with fossil fuel combustion.
<h3>What are fossil fuels?</h3>
