Answer:

- Measurement in Ci/Bq

- The amount of radioactive materials released into the environment.

- Number of disintegrations of radioactive atoms in a radioactive material over a period of time.

Explanation:

Hello,

In this case, the following options are valid:

- Measurement in Ci/Bq : one becquerel is understood as the quantity of a radioactive element in which there is one atomic disintegration per second.

- The amount of radioactive materials released into the environment: this technique is suitable to compute the amount of radioactive materials that are being or were released to the environment.

- Number of disintegrations of radioactive atoms in a radioactive material over a period of time: this technique provides becquerel which were described on the first option.

Best regards.

a sample of argon gas is cooled and its volume went from 380. mL to 250. mL. If its final temperature was -55.0C, what was its o
inn [45]

Answer:

The initial temperature was 58.4°C

Explanation:

Given the following data:

initial volume = V₁ = 380 mL = 0.38 L

final volume = V₂ = 250 mL = 0.25 L

final temperature = T₂ = -55°C = 218 K

According to Charles's law, the volume of a gas is <em>directly proportional to the temperature</em> (in Kelvin). The mathematical expression is:

V₁/T₁= V₂/T₂

So, we calculate the initial temperature (V₁) as follows:

T₁ = T₂/V₂ x V₁ = 218 K/(0.25 L) x 0.38 L = 331.36 K ≅ 331.4 K

Finally, we convert the initial temperature from K to °C:

T₁= 331.4 K - 273 = 58.4°C

What is the mass of 5.35×1021 platinum atoms?
inysia [295]
Atomic weight of a Platinum:
195.078 u = 195.078 * 1.66 * 10^(-27) kg = 3.2382948 * 10^(-25) kg
m ( Pt ) = 3.2382948 * 10^(-25) * 5.35 * 10^(21) = 
= 1.732488 * 10^(-3) kg = 1.732448 g

Does anyone know the answer to this? is it A?
AfilCa [17]

Answer:

1/2     ( the two answers given are not FRACTIONS)

Explanation:

Moles of  CH3OH   = 128 gm / 32 gm / mole   = 4 moles

Moles of water   72 gm / 18 gm /mole = 4

Mole fraction of CH3OH  =   4 / ( 4+4) = 4/8 = 1/2

You notice something is growing in a 100ml pot of liquid soap. You take 1ml of this liquid soap and perform a serial dilution an
andrew-mc [135]

Answer:

3'700,000 cfu

Explanation:

One way to count the amount of bacteria in a medium is by doing a dilution of the sample and count how many colonies growth. Each colony is a cfu (Colony forming units).

In the problem, you count 37 colonies. The dilution was 1:100,000. That means the bacteria present in the soap is:

37 colonies × (100,000 / 1) = <em>3'700,000 cfu</em>

<em></em>

I hope it helps!
