NH₄⁺(aq)+NO₃⁻(aq) → NH₄NO₃(s) How much energy is released when 3 moles of NH₄+ react?

How far is the region from the equator or control climate

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
