Explanation:
Hello there!
In this case, since the mass percentages in a compound which is wanted to know the molecular formula, can be assumed to be the masses, we first need to compute the moles they have in the formula unit:
Next, we divide each moles by the fewest ones (3.73 mol) in order to find the subscript in the empirical formula first:
Then, the empirical formula is BH2N whose molar mass is 26.83 g/mol, so the ratio of molecular to empirical is 80.50/26.83=3; therefore, the molecular formula is three times the empirical one:
Best regards!
The catalyst has been represented with the formula above the arrow in the chemical equation.
The catalyst has been the compound or element in the chemical reaction that helps in the lowering of the activation energy of the system and thereby leads to an increase in the rate of the reaction.
The chemical equation has been represented in the form of the chemical formula of the reactants and the products.
The catalyst has not been consumed in the chemical reaction, thus it has been represented with the formula above the arrow in the chemical equation.

Answer:
Extreme heat will cause the substance molecules to move faster and cause a phase change this phase change would occur if left in an extremely hot area causing the molecules to spread apart.
