Answer:

In a solid, they're really close together and vibrate a LITTLE, in a liquid they're kinda close together but change movement because water will change shape depending on the container they're in. For gas they are spread far from each other and vibrate A LOT

Answer: gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate but generally do not move from place to place.

The solubility of o2 at 20c is 1.38 x10^-3. the partial presure of o2 in the air at sea level is 0.27 atm. using henery;s law, c

Answer: The solubility of oxygen at 682 torr is $4.58\times 10^{-3}M$

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{A}=K_H\times p_{A}$

Or,

$\frac{C_{1}}{C_{2}}=\frac{p_{1}}{p_2}$

where,

$C_1\text{ and }p_1$ are the initial concentration and partial pressure of oxygen gas

$C_2\text{ and }p_2$ are the final concentration and partial pressure of oxygen gas

We are given:

Conversion factor used: 1 atm = 760 torr

$C_1=1.38\times 10^{-3}M\\p_1=0.27atm\\C_2=?\\p_2=682torr=0.897atm$

Putting values in above equation, we get:

$\frac{1.38\times 10^{-3}}{C_2}=\frac{0.27atm}{0.897atm}\\\\C_2=\frac{1.38\times 10^{-3}\times 0.897atm}{0.27atm}=4.58\times 10^{-3}M$

Hence, the solubility of oxygen gas at 628 torr is $4.58\times 10^{-3}M$

If the equation CO(g) + 2H2(g) →← → ← CH3OH(g) + energy is for a system at equilibrium, increasing the temperature will cause __

Eddi Din [679]

Answer:

[CH₃OH] to decrease and [CO] to increase.

Explanation:

Since the energy appears as a product. So, the system is exothermic that releases heat.

Increasing the temperature of the system will cause the system to be shifted to the left side to attain the equilibrium again.

So, the right answer is:

[CH₃OH] to decrease and [CO] to increase.

Give the conjugate acid for each compound below. co3^2-

DENIUS [597]

A conjugate acid is a conjugate base with hydrogen ions attached to it. In this case, the conjugate base is the carbonate ion, CO₃⁻². This ion can have two hydrogen ions, so the conjugate acid is:

H₂CO₃

This compound is known as carbonic acid.

Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius

kap26 [50]

Answer:

31.1°C

Explanation:

Given parameters:

Temperature = 88°F

The formula of the to convert is:

T°F = T°C - 32 / 1.8 = $\frac{TC - 32}{1.8}$
