A few pieces of dry ice, CO2(s), at -78°C are placed in a flask that contains air at 21°C. The flask is sealed by placing an uninflated balloon over the mouth of the flask. As the balloon inflates, the dry ice disappears and no liquid is observed in the flask.State the direction of heat flow that occurs between the dry ice and the air in the flask. Write the name of the process that occurs as the dry ice undergoes a phase change in the flask.

One major goal of the Progressive movementwas to
(1) balance the federal budget by decreasing
spending
(2) provide unemployment insurance to workers
(3) limit direct citizen control over government
(4) pass laws to help solve economic and social
problems

Answers

Answer:

The correct answer is option 4-pass laws to help solve economic and social problems

Explanation:

Hello! Let's solve this!

The progressive movement was from the decade of 1890 until 1920. The objectives were to eliminate the problems of industrialization, corruption, urbanization.

The correct answer is option 4-pass laws to help solve economic and social problems

Final answer:

The Progressive movement aimed to pass laws to help remedy economic and social problems, rather than balance the federal budget or limit direct citizen control over the government.

Explanation:

The Progressive movement in the United States, which spanned the late 19th to early 20th centuries, primarily focused on making political, economic, and social reforms to better serve the interests of the majority of Americans. The goal of the movement was not to balance the federal budget by decreasing spending nor to limit direct citizen control over government, but to pass laws that could alleviate or address socio-economic issues. Therefore, among the options given, option (4), pass laws to help solve economic and social problems, best describes a major goal of the Progressive movement.

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas

Answers

A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.

out of barium, chlorine, iodine, and strontium which atom has the strongest attraction for electrons in a bond formation?

Answers

Out of the choices given, the correct answer would be chlorine. It is the atom with the strongest attraction for electrons in a bond formation. This is because it has the highest electronegativity among the choices.

the relative atomic mass of boron 10.2.if the element occurs in two isotopic forms,boron-10 and boron-11 ,what are their geometrical abundances?

Answers

The correct answer for the question that is being presented above is this one: 

Boron consists of two isotopes, boron-10 and boron-11.
Given that its relative atomic mass is 10.2

Find the abundance of each isotope.

Let y/100 = the abundance of copper-10
and (100 - y)/100 = the abundance of copper-11

10.2 = (y/100 x 10) + [(100 - y)/100 x 11] 
10.2 = 10y/100 + 1100/100 - 11y/100 
1020 = 10y + 1100 - 11y 
-80 = -y 
y = 80

Abundance of boron-10 = 10/100 = 10%

Abundance of boron-11 = 100 - 10 = 90%
