A student heats calcium carbonate to produce calcium oxide, according to the following equation: CaCO3 (s) ➔ CaO (s) + CO2 (g)
If the student starts with 100.0 grams of CaCO3 and makes 45.0 g of CaO, what is his percent yield?

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

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.
