What mass of propane, C3H8, must be burned in order to produce 76000 kJ energy? C3H8 + 5O2  3CO2 + 4H2O + 2200 kJ

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)

its going to be mutualism cuz they both benefit from the relationship.
