Answer:
As they absorb energy, they are broken.
Explanation:
Solutes dissolve when they interact with water. This is because, the attraction of solute particles with each other weakens and become replaced by solute-solvent interaction. As the water surrounds the solute, the solute is now said to be hydrated.
Energy is required to break solute-solute bonds. This energy absorbed in breaking solute-solute bonds is compensated for by the energy liberated when solute particles are hydrated.
If energy required to break solute-solute interaction is less than the energy liberated when solute particles are hydrated, the substance will dissolve in water.
Hence, as a substance dissolve in water, energy is absorbed when solute-solute interactions are broken.
Answer:
1 mol SO2 contains 6.0213*10^23 molecules
6.023*10^24 molecules = 10 mol SO2
Equation
S(s) + O2(g) → SO2(g)
1 mol S reacts with 1 mol O2 to prepare 1 mol SO2
To prepare 10 mol SO2 you require : 10 mol S plus 10 mol O2
And that is the answer to the question
If you want a mass :
Molar mass S = 32 g/mol You require 10 mol = 320 g
Molar mass O2 = 32 g/mol :You require 10 mol = 320 g
Answer:
A planet's <u>hydrosphere</u> can be<u> liquid</u>, <u>vapor</u>, or <u>ice</u>. On Earth, in the places at the <u>north and south pole</u>, water exists in ice or glacier form, in the <u>atmosphere</u> it exists in vapor form and liquid water exists on the <u>surface</u> in the form of oceans, lakes and rivers. It also exists below ground as <u>groundwater</u>, in wells and aquifers. Water collects in clouds, then falls to Earth in the form of <u>rain or snow</u>,

When cool, dense air from over the water flows inland, it's called a sea breeze.
God bless!
