How many hydrogen atoms are on the reactant side of the equation below?

The answer to your question is 12 hydrogen atoms

Explanation:

Chemical equation

                        6CO₂  + 6H₂O  ⇒   C₆H₁₂O₆  +  6O₂

To know how many atoms of each element are in each side of the reaction, we must multiply the coefficient at the beginning of the compound by the number after the element.

Example

For Hydrogen

      Coefficient for H₂O = 6

      Number after H       = 2

Multiply these numbers = 6 x 2 = 12 atoms of hydrogen

the answer is a. co2, this would be colder than the : )

explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
