Answer:

= C3H4N

Explanation:

We are given; 90 grams carbon, 11 grams hydrogen, and 35 grams nitrogen.

We first calculate the number of moles of each element.

Carbon = 90g/12 g/mol

            = 7.5 moles

Hydrogen = 11 g/ 1 g/mol

                 = 11 moles

Nitrogen = 35 g/ 14 g/mol

               = 2.5 moles

The we get the mole ratio of the elements;

= 7.5/2.5 : 11/2.5 : 2.5 /2.5

= 3 : 4.4 : 1

= 3 : 4 : 1

Therefore;

The empirical formula will be; C3H4N

Which statement defines dynamic equilibrium? (5 points)
Shalnov [3]

Answer:

1. A state of balance in which the rates of the forward and reverse reactions are equal.

Explanation:

A dynamic equilibrium is like a cycle, the reactants change to products, but the products also change to reactants keeping the amount of each constant.

2. A state of balance in which the forward reaction stops but reverse reaction continues.

In this statement there isnt a equilibrium. The products will change to reactants until the reaction stops.

3. A state of balance in which the forward reaction continues but reverse reaction stops.

Here the reactants will change to products until the reaction stops.

4. A state of balance in which the forward and reverse reactions stop.

In this case the reaction has stopped.
