Answer:
1.400 mol
Explanation:
To convert grams to moles, you will need the molar mass. The molar mass of iron(iii) sulfate is 399.88 g/mol. Divide grams by the molar mass to find moles.
(560.0 g)/(399.88 g/mol) = 1.400 mol
There are 1.400 mol present in 560.0 g of iron(iii) sulfate.
Answer:
b. - 184 J/K
Explanation:
- ΔSsurr = - ΔH/T....at constant P and T.
∴ ΔHrxn = 54.2 KJ = 54200 J
∴ T = 25°C ≅ 298.15 K
⇒ ΔSsurr = - (54200 J)/(298 K)
⇒ ΔSsurr = - 182 J/K ≅ - 184 J/K
Answer:
I believe it is D, Heavy ice presses on sediment causing the formation of sedimentary rock
Explanation:
Answer:
Explanation:
A covalent bond is where electrons are shared equally between molecules. if you see the bottom of the page each oxygen is missing 2 electrons so they share two of one of their own with eachother and give oxygen a full octet. it doesnt have to be full to be a covallent bond but it just has to share them evenly rather than keep it to themselves
Answer:
HEMOGLOBIN AND OTHER COMPOUNDS.
Explanation:
In the lungs, hemoglobin, known for its deep red color, reacts with oxygen to form oxyhemoglobin. Oxyhemoglobin travels through the bloodstream to cells, where it breaks down to form hemoglobin and oxygen, and the oxygen then passes into cells.
