Answer:

Renewable: sun, wind, water,

Nonrenewable: oil, coal, natural gas

Explanation:

A renewable resource is a source that will not run out, because it can be replaced quickly. Some examples are the sun, water, wind. The Sun will shine for years to come, and there is a lot of water and wind.

A nonrenewable resource is something that cannot quickly be replaced. Some examples are coal, oil, and natural gas, also known as fossil fuels. They are named this because they are made from fossils, that took millions of years to form.

Renewable resources = Wind and water resources

Non - renewable = Fossil fuels , wildlife

What volume of a 3.0 M stock solution of H2SO4 is needed to prepare 2.8 L of a 1.6 M H2SO4 solution?

Georgia [21]

Use M1V1 = M2V2 to solve
3(V1) = 2.8 * 1.6
3(V1) = 4.48

Answer: The enthalpy of combustion, per mole, of butane is -2657.4 kJ

Explanation:

The balanced chemical reaction is,

$2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(g)$

The expression for enthalpy change is,

$\Delta H=[n\times H_f_{products}]-[n\times H_f_{reactants}]$

Putting the values we get :

$\Delta H=[8\times H_f_{CO_2}+10\times H_f_{H_2O}]-[2\times H_f_{C_4H_{10}+13\times H_f_{O_2}}]$

$\Delta H=[(8\times -393.5)+(10\times -241.82)]-[(2\times -125.7)+(13\times 0)]$

$\Delta H=-5314.8kJ$

2 moles of butane releases heat = 5314.8 kJ

1 mole of butane release heat = $\frac{5314.8}{2}\times 1=2657.4kJ$

Thus enthalpy of combustion per mole of butane is -2657.4 kJ

Explain how chemists overcome the problem of low yield In industry

mrs_skeptik [129]

High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.

I hope this helps you.
