To find the volume, we must first make sure that each of the dimensions is in the correct units before we make the calculation. Since we want cubic meters, and every dimension is in meters, we are good to go in this case.
So to solve for the volume, we must multiply each of the sides together:
If the answer must be in significant figures, then we know that we must only use two significant figures in this case, and so the volume would then be .
Answer:
Condensation
Explanation:
Condensation is when warm, gaseous water vapor cools and condenses into a liquid, forming a cloud. I wasn't sure if this made sense so I included a diagram.
Hope this helps! ☺
Answer:
H2
Explanation:
CO2 + H2 → CO + H2O
↓ (-2). 0. (+2 )(-2). (+1)(-2)
↓ ·2 (+2)
+4 (-4)
Write down the oxidation number under each element, each molecule should equal 0 unless there is a charge shown.
Oxygen, always has an oxidation number of -2 unless in a peroxide.
Hydrogen, is -1 with metals,+1 with non-metals. Hydrogen loves non-metals!
H2 is zero because any standalone element has an oxidation number of zero
What is being oxidized? Whatever is being oxidized, loses electrons and becomes more positive, it will be a whole molecule, not just an element. In this case, the H in H2 goes from 0 to (+1) so it is the oxidized molecule.
The number of subshells in any given shell is equal to that shell's number. So the first shell (n=1) contains 1 subshell (1s). The second shell (n=2) contains 2 subshells (2s and 2p). The third shell (n=3) contains 3 subshells (3s, 3p, and 3d), and the fourth shell (n=4) contains 4 subshells (4s, 4p, 4d, and 4f).
<span>All d-type subshells have 5 orbitals, regardless of which shell they're in. s-type subshells contain 1 orbital each, p-type subshells contain 3 orbitals each, and f-type subshells contain 7 orbitals each. The answer would still be "five" even if you'd said 3d, 4d, or 6d...they all have five orbitals. </span>
