Question

1. How many nitrate (NO_3)^-1 molecules would there be on each side of the balanced equation?2. Describe the steps that you should follow when writing and balancing a chemical equation: 1. 2. 3.3. How do we indicate the physical state of a reactant or product in a chemical equation?

Answer 1

Step-by-step explanation:

Here, we want to answer the questions after balancing the chemical reaction

We have this balanced chemical reaction as follows:

`\text{ 2}Al(NO_3)_3+3FeCl_2\text{ }\rightarrow3Fe(NO_3)_2+2AlCl_3`

We have balanced the chemical reaction, we can now proceed to answer the questions:

1) In the balanced reaction, we can see 6 nitrate molecules on the reactant side, and we have 6 nitrate molecules on the product side

2) Here, we want to describe the steps involved in balancing a chemical reaction:

a) We count the number of each of the atoms or molecules on both the reactant and product side

b) We place the right coefficients at the front of each element or group of elements and see if the particular element is of the same count on both the reactant and product side

c) We repeat steps a and b until we have a chemical reaction that is balanced

3) To indicate the physical state, we use the first letter in the name of the state, place in parentheses and use as a subscript

For the gaseous state, we have the indication as (g)

For the liquid state, we have the indication as (l)

For the solid-state, we have the indication as (s)

The exception is the aqueous state where we have (aq) as the indication
