Explanation:
Oxygen is really -2
While the other options in correct form is
Hydrogen O.S is +1
A pure group 1 element is 0.
And
A monoatomic ion's O.S is the charge contained by it
Answer:
The weak nuclear force is one of the fundamental forces:
Is a force that is responsible of some radiative phenomenoms, like the beta decay.
The intensity is way smaller than the one of the strong interaction, but this is because it acts in a way smaller range. And this can produce atractive and repulsive interactions.
So options D and B can be discarded.
And this force can be repulsive or attractive depending on the phenomena, so the options that are wrong are A and B, because the interaction is both things, not only one.
Answer:
a. the amount of work done on a system is dependent of pathway
Explanation:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system.
ΔU = Q - W
Where;
Q, the net heat transfer into the system depends on the pathway
W, the net work done by the system also depends on the pathway
But, ΔU, the change in internal energy is independent of pathway
Therefore, the correct option is "A"
a. the amount of work done on a system is dependent of pathway
