Given :
Number of moles of CHF₃ is 1.7 .
Solution :
We know, 1 mole of any complex contains 6.022 × 10²³ molecules.
Let, 1.7 moles of CHF₃ contains n numbers of molecules.
So, n = 1.7 × 6.022 × 10²³ molecules
n = 10.2374 × 10²³ molecules
n = 1.0237 × 10²³ molecules
Hence, this is the required solution.
Answer:
Keq = [CO₂]/[O₂]
Explanation:
Step 1: Write the balanced equation for the reaction at equilibrium
C(s) + O₂(g) ⇄ CO₂(g)
Step 2: Write the expression for the equilibrium constant (Keq)
The equilibrium constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species. The equilibrium constant for the given system is:
Keq = [CO₂]/[O₂]
The group of elements on the periodic table that does not participate in chemical bonding at all would be the noble gas elements. These either do not give, receive, and or share electrons.
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>
Fossils fuels are fuels wgich are produced from fossils which have decomposed under intense heat and pressure over a long period of time.
Fossils fuels include:
- methane
- petrol
- kerosene
- diesel oil
- coal
Fossils fuels combustion release pollutants into the atmosphere and have greatly contributed to global warming.
Since methane in fuel cells are not burned, it will help to reduce pollutants commonly associated with fossil fuel combustion.
