A cool, yellow-orange flame is used to heat the crucible. Would this affect the mass of the crucible? If so, how?
s2008m [1.1K]

Answer:

yes

Explanation:

Usually, it would not affect the crucible, but depending on the temperature of the flame the enamel of the crucible may begin to melt and stick to the metal object being used to handle the crucible. This tiny amount that is melted off can cause very small changes in the original mass of the crucible, which although it is almost unnoticeable it is still there. Therefore, the answer to this question would be yes.

If the volume of a gas container at 32.0°c changes from 1.55 l to 755 ml, what will the final temperature be?
Shkiper50 [21]
Charles law states that volume of gas is directly proportional to temperature at constant pressure.
\frac{V1}{T1} =  \frac{V2}{T2}
where V - volume and T - temperature 
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - 32 °C + 273 = 305 K
substituting these values in the equation 
\frac{1550 mL}{305 K} =  \frac{755 mL}{T}
T = 149 K
temperature in celsius = 149 K - 273 = - 124 °C
new temperature is 124 °C

A valve to a new chamber in the bottle is opened, and the gas expands to 2 x 10-3 m3. (The gas does no work in this process beca
Fed [463]

Answer:

The temperature doesn't change

Explanation:

Given that:

dU=dQ - dW

Where

  • U: internal energy
  • W: work
  • Q: heat

If the gas does no work and doesn't exchange heat with the outside there insn't a variation of the internal energy.

Internal energy is realted to the energy in the molecules, they vibration and theregore the temperature.

So, if there isn't a change in the internal energy you may say that there isn't a change in the temperature.

The increase in the volume is balanced by a decrease of the pression.

From the list below, which items describe beta decay? Check all that apply. APEX
Troyanec [42]

Answer:

C. A neutron turns into a proton

D. An electron is ejected from the nucleus

Explanation:

  • Beta decay is a type of the three major types of decays, others being alpha decay and gamma decay.
  • During a beta decay the atomic number of an atom increases by one while the mass number remains the same.
  • Beta decay may be classified as; an electron emission, positron emission and electron capture.
  • <em><u>During electron emission an energetic electron is emitted from the nucleus, together with an antineutrino and a neutron in the nucleus turns into a proton. </u></em>

You want to prepare a solution with a concentration of 200.0μM from a stock solution with a concentration of 500.0mM. At your di
Neporo4naja [7]

Answer:

1) The dilution scheme will result in a 200μM solution.

2) The dilution scheme will not result in a 200μM solution.

3) The dilution scheme will not result in a 200μM solution.

4) The dilution scheme will result in a 200μM solution.

5) The dilution scheme will result in a 200μM solution.

Explanation:

Convert the given original molarity to molar as follows.

500mM = 500mM \times (\frac{1M}{1000M})= 0.5M

Consider the following serial dilutions.

1)

Dilute 5.00 mL of the stock solution upto 500 mL . Then dilute 10.00 mL of the resulting solution upto 250.0 mL.

<u>Molarity of 500 mL solution:</u>

M_{2}= \frac{M_{1}V_{1}}{V_{2}}= \frac{(0.5M)(5.00mL)}{500 mL}= 5 \times 10^{-3}M

<u>10 mL of this solution is diluted to 250 ml</u>

M_{final}= \frac{M_{2}V_{2}}{V_{final}}= \frac{(5 \times 10^{-3}M)(10.0mL)}{250 mL}= 2 \times 10^{-4}M

<u>Convert μM</u> :

2 \times 10^{-4}M = (2 \times 10^{-4}M)(\frac{1 \mu M}{10^{-6}M})= 200 \mu M

Therefore, The dilution scheme will result in a 200μM solution.

2)

Dilute 5.00 mL of the stock solution upto 100 mL . Then dilute 10.00 mL of the resulting solution upto 1000 mL.

<u>Molarity of 100 mL solution:</u>

M_{2}= \frac{M_{1}V_{1}}{V_{2}}= \frac{(0.5M)(5.00mL)}{100 mL}= 2.5 \times 10^{-2}M

<u>10 mL of this solution is diluted to 1000 ml</u>

M_{final}= \frac{M_{2}V_{2}}{V_{final}}= \frac{(2.5 \times 10^{-2}M)(10.0mL)}{1000 mL}= 2.5 \times 10^{-4}M

<u>Convert μM</u> :

2.5 \times 10^{-4}M = (2.5 \times 10^{-4}M)(\frac{1 \mu M}{10^{-6}M})= 250 \mu M

Therefore, The dilution scheme will not result in a 200μM solution.

3)

Dilute 10.00 mL of the stock solution upto 100 mL . Then dilute 5 mL of the resulting solution upto 100 mL.

<u>Molarity of 100 mL solution:</u>

M_{2}= \frac{M_{1}V_{1}}{V_{2}}= \frac{(0.5M)(10mL)}{100 mL}= 0.05M

<u>5 mL of this solution is diluted to 1000 ml</u>

M_{final}= \frac{M_{2}V_{2}}{V_{final}}= \frac{(0.05M)(5mL)}{1000 mL}= 0.25 \times 10^{-4}M

<u>Convert μM</u> :

0.25 \times 10^{-4}M = (0.25 \times 10^{-4}M)(\frac{1 \mu M}{10^{-6}M})= 25 \mu M

Therefore, The dilution scheme will not result in a 200μM solution.

4)

Dilute 5 mL of the stock solution upto 250 mL . Then dilute 10 mL of the resulting solution upto 500 mL.

<u>Molarity of 250 mL solution:</u>

M_{2}= \frac{M_{1}V_{1}}{V_{2}}= \frac{(0.5M)(5mL)}{250 mL}= 0.01M

<u>10 mL of this solution is diluted to 500 ml</u>

M_{final}= \frac{M_{2}V_{2}}{V_{final}}= \frac{(0.01M)(10mL)}{500 mL}= 2 \times 10^{-4}M

<u>Convert μM</u> :

2 \times 10^{-4}M = (2 \times 10^{-4}M)(\frac{1 \mu M}{10^{-6}M})= 200 \mu M

Therefore, The dilution scheme will result in a 200μM solution.

5)

Dilute 10  mL of the stock solution upto 250 mL . Then dilute 10 mL of the resulting solution upto 1000 mL.

<u>Molarity of 250 mL solution:</u>

M_{2}= \frac{M_{1}V_{1}}{V_{2}}= \frac{(0.5M)(10mL)}{250 mL}= 0.02M

<u>10 mL of this solution is diluted to 1000 ml</u>

M_{final}= \frac{M_{2}V_{2}}{V_{final}}= \frac{(0.02M)(10mL)}{1000 mL}= 2 \times 10^{-4}M

<u>Convert μM</u> :

2 \times 10^{-4}M = (2 \times 10^{-4}M)(\frac{1 \mu M}{10^{-6}M})= 200 \mu M

Therefore, The dilution scheme will result in a 200μM solution.
