Answer:
Explanation:
A nonrenewable is a resource that cannot quickly be regenerated. A nonrenewable resource will eventually run out, and it cannot be remade for many years.
For example, <u>fossil fuel </u>is formed from fossils after millions of years of heat and pressure turn them into fuel. Since they take many years to create, they are a <em>nonrenewable energy source.</em>
Answer:
it's got to do something with milk I guess it's the sugary substance found in milk and it's a compound
Answer:
Option C Removing Na₂CO₃
Option E Heating the container.
Explanation:
The equation for the reaction is given below:
2NaHCO₃ (s) <=> Na₂CO₃ (s) + CO₂ (g) + H₂O (g)
Enthalpy change (ΔH) = 136 KJ
To obtain more CO₂ do the following:
1. Add more NaHCO₃
From chemical equilibrium, adding more NaHCO₃ means the reactant has increase. Thus, it (the reactant) will react to form more product (CO₂)
2. Removing any of the products. Removing any of the products implies that more reactants are in the reaction vessel than the product. Thus, the reactants will react to produce more products (CO₂)
3. Heating the container. Heating the container will lead to an increase in the temperature of the reaction. Since the enthalpy change (ΔH) is positive it means the reaction is endothermic. Thus, heating the container i.e increasing the temperature will favours the forward reaction i.e more products will be obtained.
NOTE: Pressure has no effect in the reaction system since there is no gaseous reactants.
Considering the options given above, C and E gives the correct answer to the question.
