Calculate the mass of limestone () that must be decomposed to produce 415 g of CaO is produced. The equation for the reaction is CaCo3(s)->CaO(s)+CO2(g)

In a combination reaction, 1.54 g of lithium is mixed with 6.68 g of oxygen. (a) Which reactant is present in excess? (b) How many moles of product are formed? (c) After the reaction, how many grams of each reactant and product are present? Including Li2O

(b) An unknown mass of Na3PO4(s) is dissolved in water to form 50.00 mL of solution. This is Solution A. Then 10.00 mL of Solution A is diluted with water to 50.00 mL. The final solution is Solution B. 20.00 mL of Solution B contains 4.408 x 1020 sodium ions. (NA = 6.022 x 1023 mol-1) Calculate the mass of Na3PO4(s) that was dissolved to form Solution A.

The rocket boosters of the space shuttle Discovery, launched on July 26, 2005, used a fuel mixture containing primarily solid ammonium perchlorate, NH4ClO4, and aluminum metal. The unbalanced chemical equation for the reaction is given below. (Hint: Balance the elements in the order Cl, H, O, Al, N.) Al(s) + NH4CIO4(s) Al₂O3(s) + AlCl3(s) + H₂O(l) + N₂(g) What is the mass (in kilograms) of NH4ClO4 consumed per kilogram of Al, assuming a percent yield of 87.20%? (Answer with two decimal places.)

If 2.952 g of copper(II) nitrate is reacted with sufficient sodium hydroxide, how much copper (II) hydroxide will be produced?

Morphine (C₁₇H₁₉NO₃) is a painkiller in the opiate family. A sample of morphine was discovered that had been diluted by mixing with table salt (sodium chloride). When 2.00 g of the mixture undergoes combustion, 3.17 g of CO₂ is produced. What is the mass percent of morphine in the mixture?

In a neutralization reaction, 50.00 mL of 0.8500 M phosphoric acid reacts with 2.500 g of magnesium hydroxide producing magnesium phosphate and water. What is the theoretical yield of magnesium phosphate (in grams)?      2. If 5.452 g of magnesium phosphate are produced in an experiment, then what is the percent yield?

Morphine (C₁₇H₁₉NO₃) is a painkiller in the opiate family. A sample of morphine was discovered that had been diluted by mixing with table salt (sodium chloride). When 2.00 g of the mixture undergoes combustion, 3.97 g of CO₂ is produced. What is the mass percent of morphine in the mixture?

Sodium sulfate is known to form three different hydrates. The molar mass of a hydrate of sodium sulfate with the general formula Na2SO4 · n H2O is 322.1 g/mol. What is the water of hydration (n) value.
