The answer would be B fossil fuel is used it cars so increasing human population therefore would increase the burning of fossil fuels
Answer:
Gravitational potential energy - into Kinetic energy
Explanation:
To find the molecular formula from the empirical formula, you need to find a multiple (x) that will give you the molar mass of the compound which in the question is 54 g/mol.
If C₂H₃ is the empirical formula
molar mass of empirical formula = (12 × 2) + (1 × 3) g/mol
= 27 g/mol
let x = multiple
let molecular formula = C₂ₓ H₃ₓ
multiple = molecular mass ÷ empirical mass
= 54 g/mol ÷ 27 g/mol
= 2
If molecular formula = C₂ₓ H₃ₓ
then molecular formula = C₂₍₂₎H₃₍₂₎
= <span>C₄H</span>₆
Adding heat to a system can encourage or increases a chemical reaction.
<h3>Change that can encourage a reaction</h3>
Increasing the temperature of a process, increase occurs in the average speed of the reactant molecules and we know that when more molecules move faster, the more number of molecules reacts with other molecules which results in faster formation of products.
In conclusion, adding heat is the right option.
