How many moles of sodium nitrate can be produced from 5.00 g of Na3PO4(29) ? Please show work!

In which phase(s) do the molecules take the shape of the container?

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
