Non-volatile solutes such as salt raises the boiling point of water. Hope the answer helps! Good luck!
If it's turning from a gas to a liquid it is cooling, but if it's going from a liquid to a gas, or melting point, it will heat up.
Answer;
B. arteriosclerosis
High levels of cholesterol can first lead directly to arteriosclerosis.
Explanation;
Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaque), which can restrict blood flow. The plaque can burst, triggering a blood clot.
Arteriosclerosis can occur when arteries grow thick and stiff and restrict blood flow to organs and tissues in the body. This gradual process, also known as hardening of the arteries, weakens arteries and can develop in various organs, most commonly the heart.
Mass of SnF₂ produced : 35.634 g
<h3>Further explanation</h3>
Reaction
Sn+2HF⇒SnF₂+H₂
mol Sn (Ar 118.710 g/mol) :
![\tt \dfrac{45}{118.710}=0.379](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B45%7D%7B118.710%7D%3D0.379)
mol SnF₂ = mol Sn = 0.379
