Answer:
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
A model is a purposeful representation of reality. When law is more complex and dynamic. Law is the description of an observed phenomenon. Make sense?
Hopefully that helped :)
52 g of hydrogen H₂
Explanation:
I will assume that the problem is talking about the hydrogenation of carbon dioxide CO₂ not carbon monoxide CO. It is harder to reduce carbon dioxide than carbon monoxide and if you manage to reduce carbon dioxide you can reduce the carbon monoxide as well.
This reaction it will take place in the presence of catalyst at a specific temperature and pressure.
CO₂ + 4 H₂ → CH₄ + 2 H₂O
Now taking into the account the chemical reaction we devise the following reasoning:
if 1 mole of CO₂ react with 4 moles of H₂
then 6.5 moles of CO₂ react with X moles of H₂
X = (6.5 × 4) / 1 = 26 moles of H₂
number of moles = mass / molecular wight
mass = number of moles × molecular wight
mass of H₂ = 26 × 2 = 52 g

Answer:
33.067 kg
Explanation:
1 kg = 1000 g
33067 g / 1000 g = 33.067
Answer:
10.56L
Explanation:
The following were obtained from the question given :
P1 = 845mmHg
V1 = 4.6L
P2 = 368mmHg
V2 =?
We can calculate the new volume by using Boyle's law as follows;
P1V1 = P2V2
845 x 4.6 = 368 x V2
Divide both side by 368
V2 = (845 x 4.6) / 368
V2 = 10.56L
