Protons and neutrons.

Note: They probably are ABOUT the same mass. Don't think they are exactly the same.

Hope this helps!

How much of the original amount of an isotope is present after a period of four half lives
vfiekz [6]

After 2 half-lives there will be 25% (1/4th) of the original isotope, and 75% (3/4 th) of the decay product

<h3>What is Half life period ?</h3>

A half life is a measurement of the slope of an exponential decay function.

It is also defined as, the time it takes to halve the concentration of something in a process.

Each half life you will have half of what you had at the beginning of a given half life.

If two separate containers A and B have the same volume and temperature, but container A has more gaseous molecules than B, then
topjm [15]

Answer:

Higher pressure, is the right answer.

Explanation:

The A will have a higher pressure. Since we have given the volume and temperature is same in both containers A and B. Below is the calculation for proof that shows which container has the higher pressure while keeping the volume and temperature the same.  

So, \ V_A = V_B \\\frac{n_A T_A}{P_A} = \frac{n_B T_B}{P_B} \\Here, \ T_A = T_B \\P_A = \frac{n_A}{n_B} \times P_B \\\frac{n_A}{n_B} > 1 \\\frac{P_A}{P_B} > 1 \\P_A > P_B \\

Therefore, the container “A” will have higher pressure.

What are the values of the solute amount in moles and the solution volume in liters.
worty [1.4K]

Answer:

0.250L of solution. 0.250 moles of solute.

Explanation:

As you can see in the image, there is a beaker with an amount of solution. 1/2L are 500mL and each line of the beaker represents 100mL. That means the volume of the solution is approximately 250mL = 0.250L

Molarity is an unit of concentration defined as the moles of solute per liter of solution. A solution that is 1.000M contains 1.000 moles of solute per liter of solution.

As the volume of the solution is 0.250L, the moles are:

0.250L * (1.000mol/L) = 0.250 moles of solute

the temperature of a gas is increased from 125C to 182C inside of a rigid container. the original pressure of the gas was 1.22at
Mariulka [41]

Answer:

1.39 atm

Explanation:

First find combined gas law equation. Then rearrange variable to match problem. You should get...

P2 = P1T2/T1

Next, change celcius temperatures to kelvin. Do this by adding 273 K (standard STP). Then fill in the numbers to go along with equation. You should get...

P2 = 1.22 atm x 455 K / 398 K = 1.39 atm

- If you need further explanation or more help please let me know. I would be glad to offer more of an explanation or help on other problems.
