Hmmmm not sure I’ll tell u when I know
Answer:
Refer to the attached page,
I've done the calculation over there
Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n =
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n = - for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
Answer: It is reactive
Explanation:
Platinum is the least reactive element on the reactive scale.
For example, the platinum doesn't give the reaction with the oxygen that is found in the air, even though if it is heated but platinum does show the reaction with fluorine, chlorine and at red heat. Platinum can be found in a pure form in nature.
Platinum is reactive, it can react with some elements, but it is the least reactive element and also it is called unreactive, it doesn't easily react with elements.
