HELPPP PLEASEEE....How does a glass of juice become cold when you add ice to it?
aThe ice makes the glass colder so the juice becomes colder.
bThe ice cools the glass of juice because the slow moving particles in the ice cause the particles of the juice to slow down.
cIce is colder than the juice. The cold travel from cold to warm until both items are the same temperature.
dThe juice is warmer than the ice. Heat travels in one direction until both items are the same temperature.

Organize the following solvents by increasing polarity A. Dichloromethane, ethanol, ethyl acetate, diethyl ether
B. Diethyl ether, dichloromethane, ethyl acetate, ethanol
C. Ethyl acetate, ethanol, dichloromethane, diethyl ether
D. Ethanol, ethyl acetate, diethyl ether, dichloromethane

Answers

Answer:

B. Diethyl ether, dichloromethane, ethyl acetate, ethanol

Explanation:

The polarity of solvents can be determined by their polarity indexes. Polarity index is defined as the measure of the ability of the solvent to interact with various polar test solutes.

Diethyl ether is the least polar with a polarity index of 2.8

Dichloromethane with a polarity index of 3.1

Ethyl acetate with a polarity index of 4.3

Ethanol is the most polar with a polarity index of 5.2

The differences in polarities of these solvents is due to their structure. Polar solvents have large dipole moments because they contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen.

Because of the two non-polar methyl groups in diethyl ether, it is not as polar as dichloromethane which has two electronegative chlorine atoms attached to a carbon atom. Similarly too, because diethyl ether has two strongly electronegative oxygen atoms sharing a bond with carbon, it has a larger dipole moment than dichloromethane. Ethanol has an oxygen hydrogen bond which has the largest dipole moment, thus, it is the most polar of the given solvents.

A balloon has a volume of 7.00 liters at a pressure of 740 mm Hg. If the temperature remains constant, at what pressure will the volume decrease to 2.00 liters?a. 749 mm Hg
b. 52.9 mm Hg
c. 211 mm Hg
d. 2590 mm Hg

Answers

Answer:

Explanation:

P1 x V1 = P2 x V2

7.00(740) = x(2.00)

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "") that are of interest to atmospheric chemistry. It can react with itself to form another form of , dinitrogen tetroxide. A chemical engineer studying this reaction fills a flask with of nitrogen dioxide gas. When the mixture has come to equilibrium he determines that it contains of nitrogen dioxide gas. The engineer then adds another of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the pressure of dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to significant digits.

when the pressure that a gas exerts on a sealed container changes from 3.74 atm to ____ atm, the temperature changes from 394 K to 789 K

Answers

Gay-Lussacs law gives the relationship between pressure and temperature of a gas.
It states that pressure of gas is directly proportional to the temperature at constant volume.
P/T = k
Where k - constant
P1/T1 = P2/T2
Where parameters for the first instance are on the left side and parameters for the second instance on the right side of the equation.
3.74 atm /394 K = P/789 K
P = 7.49 atm

Answer:

7.49 atm
