Answer:
The gas and food are examples of energy.
Explanation:
The reason why is that food is energy as proteins and electrolytes. Gas is a energy of fossil fuels.
So, first off let’s look at what an independent and dependent variable is.
an independent variable doesn’t change when other variables change, therefore making it alone and independent.
a dependent variable changes based on other variables.
so, i don’t have enough information on your experiment to know the answer but think to yourself, what is changing over time based on something else changing (dependent variable) or think does this thing stay the same no matter what (independent variable).
hope this helps!
Answer:
The correct answer is option 3.
Explanation:
The expression of 
is given by :
![K_w=[H^+][OH^-]](https://tex.z-dn.net/?f=K_w%3D%5BH%5E%2B%5D%5BOH%5E-%5D)
![K_w\propto [H^+]](https://tex.z-dn.net/?f=K_w%5Cpropto%20%5BH%5E%2B%5D)
![K_w\propto [OH^-]](https://tex.z-dn.net/?f=K_w%5Cpropto%20%5BOH%5E-%5D)
Rise in temperature will result in more dissociation of water molecules into hydrogen ions and hydroxide ions.
With an increase in concentration of hydrogen ions and hydroxide ions value of will also increase.
Answer:
0.572
Explanation:
The formula for ammonium nitrate is
NH4NO3
The trick here is to realize the 4 applies only to the hydrogen. The 3 applies only to the oxygen.
There are 2 nitrogens in the formula. So if the entire molecule represents 0.286 mols. The individual mols of each part of the formula is just multiplied by the number of moles of the molecule. In formula form
Number of moles of the atoms making up the molecule = number of atoms from the formula * mols of the molecule.
2*0.286 = 0.572 moles of Nitrogen

No clue who discovered it.
