Answer:
Explanation:
The spheres interact with each other, and a change in one area can cause a change in another. Humans (biosphere) use farm machinery manufactured from geosphere materials to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants. The biosphere contains all the planet's living things.
The answer is C because it's the only that pertains to climate change. The other answers are more about local economy.
Answer:
At 10 ∘C , the solubility of potassium chloride is measured to be 31.2⋅g per 100⋅g of water.
Explanation:
Explanation:
(a) the sublimation of dry ice [conversion of CO2(s) directly to CO2(g)]
The balanced equation is given as;
CO2(s) --> CO2(g)
This reaction is endothermic, hence; Heat is a reactant and is needed to start the reaction.
(b) the reaction of 1 mol of sulfur dioxide with oxygen.
The balanced equation is given as;
2SO2 + O2 --> 2SO3
This reaction is exothermic, hence; Heat is a product and is given off by the reaction.
