Hello,
The answer is option A "<span>the heat from the stove".
Reason:
The answer is option A because the variable the heat from the stove is causing the ice to change into water. Its not option B because thats not in the procedures. Its not option C because it is not a variable. Its also not D because thats also not a variable.
If you need anymore help feel free to ask me!
Hope this helps!

Protons, Electrons, and Neutrons are all parts of atoms, the electrons are on the outside rings of the atom, with the neutrons and electrons on the inside of the atom. The electrons are negatively charged, while the protons are positively charged and the neutrons no charge/neutral. Let me know if you would like to learn more!
Answer:
The required volume is 1.12 L.
Explanation:
Given,
Mass of O2 gas= 1.60 grams
We know,
Number of moles = Mass/Molecular mass
= 1.60/32 [Molecular mass of O2 gas is 32 gram]
= 0.05
Again,
We know that at STP,
Number of moles = Volume in L / 22.4 L
or, Volume = Number of moles X 22.4
or, Volume = 0.05 X 22.4
or, Volume = 1.12
∴The required volume is 1.12 L.
Answer:
Higher than 59 °C because dipole-dipole interactions in iodine monochloride are stronger than dispersion forces in bromine.
Explanation:
I just took the test and i got it right
Mass number is the sum of protons and neutrons inside an atom.
Atomic mass = no. of protons + no. of neutrons
