The isotopes are the variation in the number of neutrons (neutral charge), with increases the weight of the atom, so the first one, is related to this one.
Answer:
6.48
Explanation:
GeH4 + 3 GeF4 > 4 GeF3H
3 moles of GeF4 react to form 4 moles of GeF4
Therefore, (8 x 3/4)/0.926
= 6.48 moles
It should be true
Hope this helps good luck!!
Answer:
Hey
In science, we have facts, theories, and hypotheses. They all mean something different.
A hypothesis is a complete guess to a problem, and it can't be said that it is correct unless more evidence is found. A good example for this would be the question to "how did the universe get here?" Of course, there are many different hypotheses to this, such as the multiverse theory and also god.
A theory is different than a hypothesis. Many people think that a theory is always wrong and is just a guess (sounds similar to a hypothesis doesn't it.) Well, that's wrong. A theory is an idea about a scientific phenomenon that has sufficient evidence and is said to be the most likely possibility. A good example would be Einstiene's theory of relitavity. Today we know that it is true. The difference between a theory and fact is that a theory could be wrong, That is if there are other theories with as much or more evidence.
There isin't much to say about facts. all I can say is that it is a true statement about a scientific phenomena.
I wrote all that^.
