Balance this equation and tell what type of reaction
Ca + Pb2O3

9 Ca  + 2 Pb2O3  >  3 Ca3O2 + 4 Pb

It's a single replacement reaction

Explanation:

_9_Ca + _2_Pb2O3  > _3_Ca3O2 + _4_Pb

                        9  1   Ca  3 9

                         4  2 Pb 1  4

                         6  3  O 2 6

It's single replacement because there's only one element being replaced.

(Calcium is more reactive than Lead, so it bonds with Oxygen)

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
