  • The atomic mass of carbon is 12.011 g/mol.
  • The atomic mass of hydrogen is 1.00794 g/mol.

This means the molar mass of CH is

12.011+1.00794=13.01894 \text{ g/mol}

Dividing the given molar mass by this,\frac{104.1}{13.01894} \approx 8

This means the molecular formula is \boxed{\text{C}_{8}\text{H}_{8}}

Consider the reaction below:
melisa1 [442]

Answer:

(A) first order reaction

Explanation:

A first order reaction is a type of reaction in which the rate of the reaction depends only on the concentration on one of the reactants. Since A is the only reactant we have, it is right to deduce that this reaction is a first order reaction.

Note: while the order of this reaction is 1, its molecularity is 2. The molecularity of a reaction is the number of moles of reactants that is actually reacting.

(B) is wrong

This is because a zero order reaction is one in which the rate of reaction is not influenced by the concentrations of the reactants and hence remains constant irrespective. Since we were not furnished with this idea in the question, it is only right that we reject this answer.

(C) is wrong.

C is outrightly wrong as we have only one reactant.

(D) is wrong

We have only one reactant.

attashe74 [19]
<h2>The answer is option b "free energy is zero"</h2>

Explanation

  • The reaction that has negative free energy are called exergonic reactions that means the reactants have more free energy than the product formed.
  • The reaction that has positive free energy are called endergonic reactions that means the final state or the products formed have more free energy than the initial state or the reactants.
  • The reaction that has zero free energy occurs when the free energy of both reactants and the products are same hence the rate of formation of products and reactants are equal.
  • Therefore, when reactants and products are being formed at an equal rate the free energy is zero.

The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.
