Answer:
The difference between the two is:
![[Kr]4d^1^05s^25p^2](https://tex.z-dn.net/?f=%5BKr%5D4d%5E1%5E05s%5E25p%5E2)
is the Orbital Occupancy
![[Kr]5s^24d^1^05p^2](https://tex.z-dn.net/?f=%5BKr%5D5s%5E24d%5E1%5E05p%5E2)
is the Orbital Filling Order
Both are correct, I don't think your teacher will be so nit-picky to care.
I believe it to be C
Explanation: The concentration of carbon dioxide in Earth’s atmosphere is currently at nearly 412 parts per million (ppm) and rising. This represents a 47 percent increase since the beginning of the Industrial Age, when the concentration was near 280 ppm, and an 11 percent increase since 2000, when it was near 370 ppm.
Answer:
B. That energy can only be converted between different forms
Explanation:
The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.
Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.
Energy according to the law of conservation of energy is not produced neither is it destroyed.
Energy is simply transformed from one form to another.
True- For example, woodchucks are also called "groundhogs" and "whistlepigs"; but when using the scientific name scientists know they're talking about animal.
Answer:
Explanation:
Graham’s Law applies to the effusion of gases:
The rate of effusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases, the ratio of their rates of effusion is
The time for diffusion is inversely proportional to the rate.
Let CO₂ be Gas 1 and O₂ be Gas 2
Data:
M₁ = 44.01
M₂ = 32.00
