The amount of 1.50 M HCl required to react completely with 0.500 g of zinc metal is to be calculated. Concept introduction: The stoichiometry of a chemical species that is involved in a chemical reaction represents the amount of the chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected quantity of reactant and product. The stoichiometry of a chemical species is also represented in number of moles. The number of moles of a substance is given as, n = m M Where, • m represents the mass of the substance. • M represents the molar mass of the substance.

Predict the major products of this organic reaction: HBr (1 equiv) cold ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions. dm Re Explanation Check ©2025 McGraw Hill LLC.
