The boiling point and distillation temperature of a substance are the same. The answer would be True
Answer:
ΔG° = -8.8 kJ/mol
Explanation:
The standard Gibbs free energy of reaction (ΔG°) can be calculated using the following expression.
ΔG° = ΔH° - T.ΔS°
where,
ΔH°: standard enthalpy of reaction
T: absolute temperature
ΔS°: standard entropy of reaction
At 298 K (the temperature that is usually used), ΔG° for the hydrolysis of lactose is:
ΔG° = ΔH° - T.ΔS°
ΔG° = 0.44 kJ/mol - 298 K × 0.031 kJ/mol.K
ΔG° = -8.8 kJ/mol
Answer:
Groups 14, 15, and 16 have 2,3, and 4 electrons in the p sublevel (p sublevel has 3 "spaces" AKA orbitals), because Hunds says one in each orbital before doubling up if you had 2 electrons, group 14, they would both be in the first orbital, with 3 electrons, group 15, two in the first orbital one in the 2nd none in the 3rd. With 4 electrons, group 16, then you would have 2 in the first 2 orbitals and NONE in the 3rd.
Explanation:
If you are in group 13 you only have 1 electron so it can only be in one orbital. with group 17, you have 5 electrons, so 2 in the first 2 in the second and 1 in the 3rd, correct for Hunds rule anyway. Noble gasses, group 18, have 6 elecctrons, so every orbital is full any way you look at it.
Am i too late or do you still need the answer? if so i got you
Answer:
26.85 grams
Explanation:
The formula for mole calculations is number of moles = given mass/gram-formula mass.
The number of moles is given to us, which is 0.125.
The gram formula mass of SnSO4 is about 214.77.
Plug in the values we have into the equation. It should look like this:
0.125 = x / 214.77
Solve for x by multiplying 214.77 and 0.125. The answer should be about 26.85 grams.
