Electric generating plants transport large amounts of hot water through metal pipes, and oxygen dissolved in the water can cause a major corrosion problem. hydrazine (n2h4) added to the water avoids the problem by reacting with the oxygen: n2h4(aq) + o2(g) → n2(g) + 2 h2o(l) about 4 × 107 kg of hydrazine is produced every year by reacting ammonia with sodium hypochlorite in the raschig process:

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

Sodium sulfate dissolves as follows: na2so4(s) → 2na+(aq) + so42- (aq). how many moles of na2so4 are required to make 1.0 l of solution in which the na concentration is 0.10 m?
