that is the one i need help with ​

Answer:

Explanation:

n = 1.23

V = 3.00 L

T = 32C = 305.15K

P = ?

Follow this equation below

P x 3.00 = 1.23 x 0.08206 x 305.15K

P x 3.00 = 30.8

Dividing both sides by 3.00

P = 10.3 atm

Hope this helps!!

The pressure inside a 3.00 L ball that contains 1.23 moles of air at 32 degrees C is 10.25 atm.

Pressure of gas will be calculated by using the ideal gas equation as:

PV = nRT, where

On putting all values, we get

P = (1.23)(0.082)(305) / (3) = 10.25 atm

Hence required pressure is 10.25 atm.

Considering the definition of Q, the reaction quotient Q has a value of 450.

The reaction quotient Q is a measure of the relative amount of products and reactants present in a reaction at a given time when a reaction has not yet reached equilibrium.

For the reaction aA + bB ⇄ cC + dD, Q adopts the expression:

[tex]Q=\frac{[C]^{c}[D]^{d} }{[A]^{a} [B]^{b} }[/tex]

That is, Q is defined as the ratio between the equilibrium concentrations of products and reactants raised to their respective stoichiometric coefficients, at a given temperature.

Comparing Q with Kc allows us to find out the state and evolution of the system:

In this case the system is:

H₂(g) + I₂(g) ↔ 2 HI(g)

So, Q adopts the expression:

[tex]Q=\frac{[HI]^{2} }{[H_{2} ] [I_{2} ] }[/tex]

You know:

Replacing in the expression of Q:

[tex]Q=\frac{(3 M)^{2} }{(0.2 M) (0.1 M)}[/tex]

Solving:

[tex]Q=\frac{9 M^{2} }{0.02 M^{2} }[/tex]

Q= 450

Finally, the reaction quotient Q has a value of 450.

In this case, the reaction quotient is greater than the equilibrium constant, Q > Kc. Then, the system is not in equilibrium. The forward reaction predominates and the system will evolve to the left to increase the concentration of reactants.

The pOH of a solution is 6, then the pH of the solution is 8 moles per liter.

pOH of any solution defines as the negative logarithm of the concentration of hydroxide ions (OH⁻).

In the question given that,

pOH of the solution = 6

i.e. -log[OH⁻] = 6

[OH⁻] = 10⁻⁶

Also we know that, pH + pOH = 14

pH = 14 - 6 = 8 mol/L

Hence, pH of the solution is 8 mol/L.

Some of the negative consequences of cobalt mining are pollution and child trafficking.

Many young children are made to work in mines generally either due to continued struggle for survival or forced into it by child traffickers.

Apart from that, cobalt mining causes pollution in the environment. Inhalation of dust containing cobalt causes a host of health issues such as lung cancer and damage to human skin.

Other effects include soil degradation and pollution, water pollution due to mine run-offs, etc.

P, R, and T are constant, then the volume is directly proportional to the mole. Then the correct option is A.

An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.

Given

A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.

[tex]V_1=5\ ml[/tex]

[tex]V_2=1000\ ml[/tex]

[tex]n_1=0.040\ mole[/tex]

We know the equation of the ideal gas.

[tex]PV=nRT[/tex]

where P, R, and T are the constant, then

[tex]\dfrac{V_2}{V_1}=\dfrac{n_2}{n_1}[/tex]

[tex]V_2=n_2\times \dfrac{V_1}{n_1}[/tex]

Thus, the correct option is A.

If a cheetah can run 1 meter in 0.0346812 seconds, the cheetah can run 64.5mph.

The average speed of a moving body can be calculated by dividing the distance moved by the body by the time taken. That is;

Average speed = Distance/Time

Average speed = 1m/0.0346812s

Average speed = 28.83m/s.

The average speed in m/s can be converted to mph as follows:

1 metre per second = 2.237 miles per hour

28.83m/s = 64.5mph

Therefore, if a cheetah can run 1 meter in 0.0346812 seconds, the cheetah can run 64.5mph.
