What is the difference between reactants and products in a chemical equation (Explain)? In the equation “carbon plus oxygen makes carbon dioxide”, what substance(s) is/are the reactant(s)? What substance(s) is/are the product(s) (Explain).

Explanation:

Reactants can be referred to as starting materials for a chemical reaction. They undergo a change to form products. Reactants are usuallyconsumed in the reaction process.

Reactants are written at the left side before the arrow sign in a reaction.

Products are the ending materials of a reaction. They are what is left after the reactants has been consumed.

Prpducts are written on the right side after the arrow sign in a reaction

Basically, a reaction is given as;

Reactants --> Products

A + B --> C + D

A and B are reactants and C and D are products

In the reaction;

“carbon plus oxygen makes carbon dioxide”

C + O2 --> CO2

The reactants are; C and O2.

The product is CO2

The answer to your question is given below

Explanation:

A. The difference between reactants and products in a chemical equation is that the reactants are located on the left hand side of the equation while the products are located on the right hand side of the equation.

B. When carbon (C) combine with oxygen (O2) to produce carbon dioxide (CO2), the details of the reaction are given below:

Reactants => C and O2

Product => CO2.

The balanced equation is given below:

C + O2 —> CO2

C and O2 are located on the left side which indicates that they are the reactants while CO2 is located at the right side which indicates that it is the product.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
