what element is a metalloid

Is H3PO4 a triprotic or diprotic acid, if it is a trprotic acid, then how do we explain its reaction with sodium hydroxide? i.e. H3PO4 + 2NaOH == Na2HPO4 + 2H2O.

what is the mass of silver nitrate that can be prepared from 1.00g of copper metal?

Suppose you pour 20 mL of silver nitrate into a beaker with 80 mL of water (H20) in it. You
also pour 20 mL of silver nitrate into a separate beaker, but this one contains 80 mL of salt
water (NaCl). Is the percent strength of the silver nitrate the same in both of these solutions?

If, under certain conditions, 1.4 g of X reacts with 2.1 g of Z to produce 3.5 g of X2Z3, then, under different conditions, if 0.80 g of X reacts with 1.6 g of Z to produce 2.4 g of a new compound, what is the formula for this new compound?

Determine the density of air in grams per liter at a temperature of 20.5 deg. C and a pressure of 755 mmHg. Assume that air is approximately 20% O2 and 80% N2 (i.e. the mole fraction of oxygen is 0.20 and the mole fraction of nitrogen is 0.80)
