Polychlorinated biphenyls (PCBs), which were formerly used in the manufacture of electrical transformers, are environmental and health hazards. They break down very slowly in the environment. The decomposition of PCBs can be represented by the equation 2CH.CI + 230, + 2H, 0 24C0, + 12 HCI How many moles of water are needed to react with 10.0 mol 0,2 moles of water: How many grams of HCI are produced when 15.2 mol H, reacts? HCI produced: How many moles of...

Dinitrogen oxide, commonly called laughing gas, is sometimes used as an anesthetic in dentistry. It is produced by the decomposition of ammonium nitrate. The other product of this reaction is water. A balanced equation indicates the mole ratios of reactants and products. The molar mass of a substance allows you to convert between moles and mass. ______________________________________________________________________________ Write the balanced equation for the production of dinitrogen oxide and water from ammonium nitrate. How many grams of ammonium nitrate are required...

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...

Review I Constants Learning Goal: Correct To understand how to use stoichiometry to convert between quantities of reactants and products in chemical equations. Stoichiometry describes the quantitative relationships among the reactants and products of a balanced reaction by directly comparing mole ratios. Stoichiometry can be used to convert mass, number of moles, or number of particles between products and reactants, as shown in the flowchart displayed in the figure. (Figure 1) Part B How many grams...
