Balance the following chemical reactions:

1. Pb(NO₃)₂ → PbO + NO₂ + O₂

2. CH₄ + O₂ → CO₂ + H₂O

3. Cu + AgNO₃ → Cu(NO₃)₂ + Ag

4. MnO₂ + HCl → MnCl₂ + H₂O + Cl₂

5. Pb(NO₃)₂ + NaCl → PbCl₂ + NaNO₃

Write the chemical reaction and balance it.

1. A solution of potassium chloride when mixed with silver nitrate solution, an insoluble

white substance is formed.

2. Copper sulphate on treatment with potassium iodide precipitates cuprous iodide(Cu₂l₂),

liberates iodine gas and also forms potassium sulphate.

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
