Hello!
Whenever you see an atomic number with an element, you know the number of protons in the nucleus of the atom, which determines the chemical of an element and its place on the periodic table.
For example, Hydrogen has only one proton, however, if you were to add say 78 more protons, you'd get gold!
1.8e-6 this should be the correct answer according to my mass converter.
Answer:
80.7 L
Explanation:
PV = nRT
P = 1520 mmHg = 2 atm
n = 5 mol
R = 0.08206 (L * atm)/(mol * K)
T = 393.15 K
2 (V) = 5 (0.08206) (393.15)
V ≈ 80.7 L
<span>Answer:
CO2→CO + 12O2 is not a balanced reaction, I think you meant to post " CO2→CO + 1/2O2"
The simple answer is that the enthalphy for reaction 1 reversed is the same enthalpy as for the reaction as written but with the opposite sign.
If A + B = AB with 30 kJ released then
AB = A + B with 30 kJ absorbed.
We would write it as
A + B = AB heat of reaction = -30 kJ
AB = A + B heat of reaction = +30 kJ</span>
