When 78.0 g of aluminum hydroxide, Al(OH)3 (molar mass = 78.0 g/mol), reacts with 49.0 g sulfuric acid, H2SO4 (molar mass = 98.1 g/mol), what mass of water is produced?

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
