Answer: B. ![\frac{\text {2 mol} H_2O}{\text {2 mol HCl}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%20%7B2%20mol%7D%20H_2O%7D%7B%5Ctext%20%7B2%20mol%20HCl%7D%7D)
Explanation:
The balanced chemical equation is:
is the limiting reagent as it limits the formation of product and is the excess reagent.
According to stoichiometry :
2 moles of produce = 2 moles of
Thus 3.25 moles of
will produce=
of ![H_2O](https://tex.z-dn.net/?f=H_2O)
Thus the tile used is ![\frac{\text {2 mol } H_2O}{\text {2 mol HCl}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%20%7B2%20mol%20%7D%20H_2O%7D%7B%5Ctext%20%7B2%20mol%20HCl%7D%7D)
Answer:
Your answer is b
Explanation:
the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.
Explanation:
Carbon has 3 isotopes. Carbon-12, Carbon-13, and Carbon-14
All of them have an atomic number of 6, which means all of them have 6 protons (if they had different numbers of protons, they'd be different elements).
Since they all have 6 protons, in their elemental forms, they all have 6 electrons, too.
Carbon-12:
Atomic number: 6
Mass number: 12
protons: 6
electrons: 6
neutrons: 6
Carbon-13:
Atomic number: 6
Mass number: 13
protons: 6
electrons: 6
neutrons: 7
Carbon-14:
Atomic number: 6
Mass number: 14
protons: 6
electrons: 6
neutrons: 8
