Answer: Physical change
Explanation: I said physical change because its changing the form of the substance and also solid to gas are sublimating
Answer:
false should be the correct response.
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)
Energy cannot be created nor destroyed. :)
I would say the answer is C. Mutualism
