Give an example of a chemical equation?

Answer 1

the first one i can come up with is the equation for photosynthesis.

Listing all reactants and products, photosynthesis can be described as:

6 CO2 + 12 H2O → C6H12O6 + 6 O2 + 6 H2O

But because water is both a reactant and a product, the equation can be simplified accounting for net water consumption, which is:6 CO2 + 6 H2O →C6H12O6 + 6 O2

Carbon dioxide + Water + Light energy → Glucose + Oxygen

Answer 2

The formation of water from Oxygen and Hydrogen:

One molecule of Oxygen (O2) reacts with two molecules of Hydrogen (H2) to produce two molecules of Water (H2O) with the release of some thermal energy.

O2+2H2 = 2H2O

Answer 3

phosphorus oxygen--tetraphosphorus decoxide?ok, they don't give you any other info than what you have and what you need to make.

what you need to know to balance this is that phosphorus occours as P4 when you see an equation that just gives elemental phosphorus assume its P4 unless they state otherwise, and oxygen as O2

Tetraphosphorus decoxide will have a formula of P4O10

so we'll need 5 lots of O2 to get 10 on the right hand side and the left hand side, and P4 is already on both sides so that's fine

Your full balanced equation is

P4 + 5O2 <-----> P4O10

Answer 4

Hydrochloric acid reacts with sodium to form sodium chloride and hydrogen gas. 2HCl + 2Na -> 2NaCl + H2

Answer 5

An easy and useful example of chemical reaction is to mix baking soda and vinegar. When combined, they fizz a lot, which makes a great (and safe) drain cleaner.

Answer 6

iron+hydrochloric acid -----> ironchloride + hydrogen :)

Answer 7

here is a good one for ya. yo mama + me = you! lololol

Answer 8

Fe + S ---> FeS
