the oxidizing agent and reducing agent in each of the following reactions : . iron (III) oxide + carbon → iron + carbon dioxide ammonia + copper (II) oxide → copper + water + nitrogen

Each iron atom in Fe2O3 decreases its oxidation number from +3 to 0, so each Fe atom in Fe2O3 is reduced, and Fe2O3 is the oxidizing agent.

Copper has a specific heat of approximately 0.40 J/g *C 1000J of energy is required to heat a sample of copper from 15*C to 40*C what is the mass of the sample of copper?

Heat required= mass of copper × specific heat of copper × change in temperature1000J = mass of copper× 0.40 J/g C × 25CMass of copper = 100g

Copper reacts with chlorine to form two compounds. Compound A consists of 4.08 g of copper for every 2.28 g of chlorine. How much copper is needed to combine with 1 g of chlorine in compound A?

4.08=2.28?= 1= 4.08/2.28= 1.79g

given that the dominant isotope mass for copper metal is 62.94 amu (g/mol) how many atoms of copper metal are in a pure copper coin that weighs 2.15g

n(Cu) = 2.15 / 62.94 = 0.0342 (mol); N(Cu) = 0.0342 * 6.02 *1023 = 2.06 *1022 Answer: 2.06 *1022 atoms

When 250 kg of copper (I) oxide is heated with 129 kg of copper (I) sulfide, 285 kg of copper is recovered. Calculate the theoretical yield of copper.

2Cu2O + Cu2S -> 6Cu + SO2n= m/Mn(Cu2O)= 250000g/143.09g/mol= 1747 moln(Cu2S)= 129000g/ 159.16 g/mol= 810.5 molFind limiting reactant: compare1747/2 and 810.5873.5>810.5, consequently , Cu2S is a limiting reactant.According to equation...

how many atoms of copper are there in a piece of copper that weighs the same as a piece of aluminum that contains 4.86 x 10(21) atoms of aluminum

Let's find out the amount of Aluminium.n = NAl / NA = 4.86 × 1021 / 6,02 × 1023 = 0.807 × 10-2 (mol);Now we can find out the mass...
