Step 1: add electrons to fill the 1s subshell (maximum of 2 electrons), when this is full, go to step 2. Step 2: add electrons to fill the 2s subshell (maximum of 2 electrons), when this is full, go to step 3. Step 3: add electrons to fill the 2p subshell (maximum of 6 electrons), when this is full, go to step 4. Step 4: add electrons to fill the 3s subshell (maximum of 2 electrons), when this is full, go to step 5. Step 5: add electrons to fill the 3p subshell (maximum of 6 electrons), when this is full, go to step 6. Step 6: add electrons to the 4s subshell (maximum of 2 electrons), when this is full, go to step 7. Step 7: add electrons to the 3d subshell (maximum of 10 electrons), when this is full, go to step 8. Step 8: add electrons to the 4p subshell (maximum of 6 electrons), when this is full, go to step 9. etc
So for Cu would be: 1s^22s^22p^63s^23p^63d^9
Ag would be: 1s^22s^22p^63s^23p^63d^104s^24p^64d^105s^1
Au would be: 1s^22s^22p^63s^23p^63d^104s^24p^64d^105s^25p^64f^145d^106s^1
The answer is D. CaCl2 and H2O
Answer:
Part A - The combined angular momentum of the masses is 0.48 kg-m^2/s.
Part B - 0.0495 is her linear speed.
Explanation:
Part A - We know that angular momentum is the measure of the amount of rotation of the body and is the product of of the moment inertia and the angular velocity. The equation for the moment of inertia can be expressed as l=mr^2 in which m is the mass and r is the radius of the circle. According to the problem, r is 0.6m. Then, l=2kg*(0.6)^2=0.72kg-m2/s2. We also know that angular velocity is the product of linear velocity and the radius which can be expressed as w=rv. Therefore, w=0.6*11 which equals to 0.66 rad/s. The angular momentum is 0.72 kg-ms/s2*0.66 rad/s. Which equals to 0.48 kg-m^2/s.
Part B - First we use l=mr^2, where m=2 kg and r=0.15m. 0.15 becomes 0.225 and when multiplied with 2 is 0.045, giving us the moment of inertia to plug in the following equation. L=l*w where l is 0.045 and w is 1.1 m/s. 1.1 times 0.045 is 0.0495 which is in other words, her linear speed.
I am rusty with this, but I hope it helps!
If all the reactors are used, the pressure inside the flask will most likely increase to 4 atm.
<h3>What is atmospheric pressure?</h3>
Atmospheric pressure is a force per unit area exerted by the air in the atmosphere on the Earth's surface. The value of atmospheric pressure above sea level is 1013.25 hPa.
<h3>What influences the variation of atmospheric pressure?</h3>
The atmospheric pressure varies from different meteorological factors such as:
- Decreases with altitude.
- It varies according to latitude, the lowest atmospheric pressure at sea level is reached in the equatorial latitudes.
- The equatorial zone has high atmospheric pressures for dynamic reasons derived from the Earth's rotation.
According to the above, if all the reactors are used at atmospheric pressure, it will most likely increase.
Note: This question is incomplete because some information is missing. However I can answer it based on my prior knowledge.
