how do an ionic bond and a covalent bond differ?
question 1 options:
a. there is no difference. both an ionic bond and a covalent bond share electrons.
b. there is no difference. both an ionic bond and a covalent bond are attractions between oppositely charged ions.
c. an ionic bond is an attraction between oppositely charged ions. a covalent bond is a sharing of electrons between atoms.
d. a covalent bond is an attraction between oppositely charged ions. an ionic bond is a sharing of electrons between atoms.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
