3) HCN + CuSO4 H2SO4 + Cu(CN)2 Mole Ratio?
How many moles of H2SO4 can be made from 250 g of CuSO4?
How many grams of HCN do you have if you made 275 g of Cu(CN)2?
How many moles of H2SO4 can be made from 8.9 moles of HCN?

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)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

what is the question?

b. is the answer hoped i
