Hydrazine reacts with dinitrogen tetroxide according to the equation: 2N2H4(g) + N2O4(g) → 3N2(g) + 4H2O(g)
50.0 grams of hydrazine is mixed with 100.0 grams of dinitrogen tetroxide. How much nitrogen gas was produced?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

Using the periodic table, complete the table to describe each atom. type in your answers.a ? b? c? d? e? f?

Can someone me with questions 12 and 13 plz.
