Answer:
This happens when there are too many protons in the nucleus, because the positive protons repel each other. When two protons fuse together, one of them decays into a neutron. Our new nucleus now has one proton and one neutron. PLEASE MARK AS BREINLEST.
The Answer for this question is Meter
Answer:
C.
Explanation:
Phase change is physical.
Answer is: Volume of hydrogen sulfide is 131,37 L.
m(H₂S) = 200,0 g.
n(H₂S) = m(H₂S) ÷ M(H₂S).
n(H₂S) = 200 g ÷ 34,1 g/mol.
n(H₂S) = 5,865 mol.
V(H₂S) = n(H₂S) · Vm.
V(H₂S) = 5,865 mol · 22,4 L/mol.
V(H₂S) = 131,37 L = 131,37 dm³.
n - amount of substance.
Vm - molar volume.
