Answer:

The answer to your question is   P2 = 280 mmHg

Explanation:

Data

Pressure 1 = P1 = 400 mmHg

Volume 1 = V1 = 1.75 L

Pressure 2 = ?

Volume 2 = 2.5 L

Process

1.- Use Boyle's law to solve this problem

                  P1V1 = P2V2

-Solve for P2

                     P2 = P1V1 / V2

2.- Substitution

                    P2 = (400)(1.75) / 2.5

3.- Simplification

                   P2 = 700 / 2.5

4.- Result

                   P2 = 280 mmHg

Vedmedyk [2.9K]

Answer:

See explanation

Explanation:

Sublimation refers to the movement of molecules directly from solid into the vapor or gas phase while deposition refers to the movement of  molecules directly from the gas phase into the solid phase. The two are opposite to each other.

Frost is formed in a situation where a substance cools to a temperature that is lower than its dew point. In this situation, the vapour is directly deposited on a surface to form a frost without passing through a liquid phase. Hence the name, deposition.

How do you name ethers in chemistry?
aleksley [76]

Answer:

Common names of ethers simply give the names of the two alkyl groups bonded to oxygen and add the word ether. The current practice is to list the alkyl groups in alphabetical order (t-butyl methyl ether), but older names often list the alkyl groups in increasing order of size (methyl t-butyl ether).

How many electrons does an ion of magnesium have if it’s represented by the symbol shown below? 25Mg2+
Galina-37 [17]

Answer:

10 electrons.

Explanation:

Hello!

In this case, since a normal atom of magnesium has 12 protons and electrons when is not in the form of a cation, since it is a metal that tends to lose electrons when ionized, and therefore it becomes positively charged, we infer  that in form of:

Mg^{2+}

It only has 10 electrons.

Best regards!
