Explanation:
Hello,
In this case, by using the Avogadro's law which allows us to understand the volume-moles behavior as a directly proportional relationship:

We can compute the volume of 34.3 g of argon by representing it in mole as shown below:

Thus, we find:

Best regards.
Answer:

Explanation:
The unbalanced nuclear equation is

Let's write the question mark as a nuclear symbol.

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
15 = 0 + A, so A = 15 - 0 = 15, and
6 = -1 + Z, so Z = 6 + 1 = 7
Then, your nuclear equation becomes

Element 7 is nitrogen, so the balanced nuclear equation is

Because of the plates crashing into each other
If you are looking for what could contradict the scientific theory, the answer would be, "new experiments that contradict the theory". If a new experiment were to be proving something inccorect or somewhat false in a theory, than what would be the greatest challenge to it would be to test it.
I hope this answer helped you!
