Answer:
D: Melting of ice. is it correct?
Answer:
Elements on the left of the period 3 have higher melting and boiling points than those on the right. These low melting and boiling points are typical of non-metals. Argon, chlorine, sulfur and phosphorus are non-metals. On the left hand side of period 3 we find the elements sodium, magnesium and aluminium.
Explanation:
In the whole of period 3, the outer electrons are in 3-level orbitals. These are all the same sort of distances from the nucleus, and are screened by the same electrons in the first and second levels. The major difference is the increasing number of protons in the nucleus as you go from sodium across to argon.
have a good day T_T
Answer:
Anything that can be done to increase the frequency of those collisions and/or to give those collisions more energy will increase the rate of dissolving.
Explanation:
depended on the temperature
I would say it’s the last answer . D. I would say this because the Germans took the Jews belongings like gold, money, jewelry, anything they had and they kept it to themselves so the Jews didn’t have anything valuable . Even their clothes.
Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
