15Steps in Reaction Stoichiometry Balance equation for the reaction.Convert known mass of reactant or product to moles.Use balanced equation to set up appropriate mole ratios.Use mole ratios to calculate moles of desired reactant or product.Convert from moles to mass or volume as required.
16SolveLithium hydroxide is used in space vehicles. to remove exhaled carbon dioxide from the environment, forming lithium carbonate and water. What mass of carbon dioxide can be absorbed by 1.00kg of lithium hydroxide?
17SolveBaking soda (NaHCO3) and milk of magnesia [Mg(OH)2] are both used as antacids to neutralize excess HCl in the stomach. Which is more effective per gram
18Limiting ReactantThe reactant that gets used up first.Limits the amount of products that can form.
19Nitrogen gas can be prepared by passing ammonia gas over solid copper(II) oxide. Solid copper and water are also produced. If 18.1g NH3reacts with 90.4g CuO, what is the limiting reactant? How much N2 can be made and how much excess reactant is left over?
20Theoretical yieldThe maximum amount of product that can be made in a perfect world.The actual yield is always less than the theoretical yield.
21Percent(%) yield%yield= actual yield x 100theoretical yield
22Methanol(CH3OH) can be produced by a combination reaction between carbon monoxide and hydrogen gas. If 68.5kg of CO reacts with 8.60kg H kg of methanol is produced. Calculate the % yield.
