Calculate the mass of water produced when 1.92 g of butane reacts with excess oxygen.

The ion with 3 + charge 28 electons and a mass number of 71

How many more h + ions does a solution with a ph of 4 than a solution with a ph of 5?

Assign an oxidation number to each element in the reaction. CaF2 (s) + H2SO4 (aq) → CaSO4 (aq) + 2HF (g) In CaF2, the oxidation number of Ca is , and that of F is . In H2SO4, the oxidation number of H is , that of S is , and that of O is .

Phosphorus is: 1 found free in the atmosphere 2 returned to the soil by rhizobium 3 added to the soil through weathering 4 usually very abundant in an ecosystem

Why should your disposal of excess magnesium take place in a fume hood? (choose all that apply) Group of answer choices The quench released hydrogen gas, which is flammable and explosive The quench is highly exothermic and might cause the solvent to

For the chemical equation SO2 (g) + NO2 (g) SO3 (g) + NO (g) SO2 (g) the equilibrium constant at a certain temperature is 3.00. At this temperature, calculate the number of moles of NO2 (g) that must be added to 2.30 mol SO2 (g) in order to form 1.
