Question

1. When 7.00moles of chlorine reacts with excess lithium How moles of lithium chloride can be produced? Must write out a balanced chemical equation first

2. How many moles of phosphorus pentaxide can be producedit 5.25 moles of oxygen reacts with excess phosphorus in the following reaction Must write a balanced chemical
Equation
3. How many moles of copper in oxide are needed to produce 7.75 mole of carbon dioxide when copper (l)oxide reacts with solid carbon. Must write a balanced chemical Equation

4. Silver nitrate reacts with bromine in a single replacement teaction
0.00883 moles of Silver nitate react How many moles of bromine would be produced

Answer 1

1. 14 moles of LiCl

2. 1.05 moles of P₄O₁₀

3. 15.5 moles of CuO

4. 0.00883 moles of Br₂

Step-by-step explanation:

1. Cl₂ + Li → 2Cl

Ratio for the reaction is 1:2, so 7 moles of Cl₂ produce the double of moles, of chloride. → 14 moles of LiCl

2. The reaction for this is:

P₄ + 5O₂ → P₄O₁₀

5 moles of oxygen produce 1 mol of phosphorus pentoxide

Then, 5.25 moles of O₂ would produce (5.25 .1) / 5 = 1.05 moles

3. The reaction for this is:

C + 2CuO → CO₂ + 2Cu

Ratio is 1:2, so 7.75 moles of CO₂ were produced by the double of moles of CuO → 15.5 moles of CuO

4. Let's think the reaction:

AgNO₃ + Br₂ → AgBr + BrNO₃

As ratio between the reactants is 1:1, 0.00883 moles of AgNO₃ need the same amount of bromine → 0.00883 moles of Br₂
