Answer:

1. 156.818182 kg

2. 22.525 gallons

3. 437.4 yds

Explanation:

1. 345/2.2 (since 2.2 lbs equals 1 kg you would divide that by the number of pounds to find kg).

2. 85 x 1.06 = 90.1 (to find the number of qts)

90.1/4 = 22.525 (there are 4 quarts in a gallon so you would divide by 4)

3. 400 x 39.37 = 15,748 (multiply number of meters by the number of inches)

15,748/36 = 437.4 (divide by 36 since you are moving to a bigger unit)

What is the similarity between simple diffusion and facilitated diffusion?
MakcuM [25]

they are both types of passive transport which means they require no energy. They both work with the concentration gradient which means they go from a high concentration area to a low concentration area. The differences are simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel

Simple diffusion: it is the process where molecules move from a area of high concentration to an are of lower concentration. There is no energy needed in simple diffusion. For example when sodium is highly concentration in a cell, it moves outside of the cell where sodium is less concentration. it takes no energy as simple diffusion is random and molecules move according to their concentration.

A sample of helium gas initially at 37.0°C, 785 torr and 2.00 L was heated to 58.0°C while the volume expanded to 3.24 L. What i
spayn [35]

Answer:

0.681 atm

Explanation:

To solve this problem, we make use of the General gas equation.

Given:

P1 = 785 torr

V1 = 2L

T1 = 37= 37 + 273.15 = 310.15K

P2 = ?

V2 = 3.24L

T2 = 58 = 58+273.15 = 331.15K

P1V1/T1 = P2V2/T2

Now, making P2 the subject of the formula,

P2 = P1V1T2/T1V2

P2 = [785 * 2 * 331.15]/[310.15 * 3.24]

P2 = 515.715 Torr

We convert this to atm: 1 torr = 0.00132 atm

515.715 Torr = 515.715 * 0.00132 = 0.681 atm
