Write the balanced NET ionic equation for the reaction when aqueous Cs₃PO₄ and aqueous AgNO₃ are mixed in solution to form solid Ag₃PO₄ and aqueous CsNO₃.

Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3C4H6O3) with salicylic acid (C7H6O3C7H6O3) to form aspirin (C9H8O4C9H8O4) and acetic acid (C2H4O2C2H4O2). The balanced equation isC4H6O3+C7H6O3→C9H8O4+C2H4O2C4H6O3+C7H6O3→C9H8O4+C2H4O2In a laboratory synthesis, a student begins with 3.10 mLmL of acetic anhydride (density=1.08gml−1density=1.08gml−1) and 1.23 gg of salicylic acid. Once the reaction is complete, the student collects 1.22 gg of aspirin.    Determine the percent yield of aspirin for the reaction. Express your answer using three significant figures.

A mixture consisting of only chromium(III) bromide (CrBr3) and aluminum bromide (AlBr3) weighs 1.1218 g. When the mixture is dissolved in water and an excess of silver nitrate is added, all the bromide ions associated with the original mixture are precipitated as insoluble silver bromide (AgBr). The mass of the silver bromide is found to be 2.2708 g. Calculate the mass percentages of chromium(III) bromide and aluminum bromide in the original mixture. Mass percent CrBr3 Mass percent AlBr3 = % %

Write a balanced chemical equation based on the following description: the reaction of aluminum metal with aqueous sulfuric acid to form aqueous aluminum sulfate and hydrogen gas

The balanced chemical equation is P₄(s) + 6 Cl₂(g) → 4 PCl₃(g). What is the mass in grams of phosphorus trichloride that can be formed from 226.0 grams of chlorine gas based on the balanced chemical equation?

Hexane is a colourless liquid with a characteristic smell that reacts with chlorine gas in the presence of a catalyst. Chlorohexane is a liquid compound that is formed through the substitution of one hydrogen in the hexane molecule with chlorine. Write the chemical equation for this reaction and explain if it requires balancing. Hydrogen chloride gas is also a product of this chemical reaction. Note: ignore the presence of the catalyst.

Acrylonitrile is an important building block for synthetic fibers and plastics. Over 2 billion pounds of acrylonitrile are produced in the United States each year. The compound is synthesized from propene in the following reaction:2C3H6 + 2NH3 + 3O2 → 2C3H3N + 6H2OWhat mass of acrylonitrile can be prepared from 150.0 kg of propene, 600.0 kg of ammonia, and 100.0 kg of oxygen?

Write a balanced equation for the Alka Seltzer reaction where aqueous citric acid, H3C6H5O7, and aqueous sodium bicarbonate, NaHCO3, react and form aqueous sodium citrate, liquid water, and carbon dioxide gas.
