Answer: If I have 17 moles of gas at a temperature of 67°C, and a pressure of 5.34 atmospheres, what is the volume of the gas? write down all the givens of the problem
Explanation:
When a chlorine atom forms an ion, it gains electrons, making it negative. A neutral chlorine will become a chlorine with a -1 charge. When it gains an electron, the radius increases.
When a sodium atom forms an ion, it loses electrons, making it positive. A neutral sodium will become a sodium with a +1 charge. When it loses an electron, the radius decreases.
Answer:
The answer is 0.01365.
Explanation:
C(t) = 0.0225te^?0.0467t
We can derivate,
C'(t) = d/dt ( 0.0225 te^-0.0467t)
after solving,
C'(t) = 0.0225 (e^-0.0467t - (0.0467e^-0.0467t . t)
Plug in t =5,
Answer is C'(t) = 0.01365.
The carboxyl group in the amino acid is always acidic
Answer:
3.76 g of O₂ are needed to produced 12.5 g of Fe₂O₃
Explanation:
The reaction is: 4Fe (s) + 3O₂ (g) → 2Fe₂O₃ (s)
4 moles of iron react to 3 moles of oxygen in order to produce 2 moles of iron (III) oxide.
Let's determine the moles of the produced product.
12.5 g . 1mol/ 159.69g = 0.0783 moles
If we assume Iron in excess, we work with the oxygen.
2 moles of Fe₂O₃ are produced by 3 moles of oxygen
Then, 0.0783 moles of Fe₂O₃ might be produced by (0.0783 . 3)/2
0.117 moles.
We convert the moles to mass → 0.117 mol . 32 g/1mol = 3.76 g
