Answer:
D
Explanation:
Sugar will dissolve faster when you stir the solution quickly because the act of stirring increases kinetic energy which increases the temperature.
Answer:
50
Explanation:
so you'll have to apply Newton's 2nd law which is F=ma and then substitute the values that you already have in the question as in, the force is 200 and you'll have to find the acceleration by working it out which is 4m/s² and then find the mass by dividing 200 by 4 so the actual mass is 50kg ✌️❤️
Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride.
<h3>What is a word equation?</h3>
A word equation represents a chemical reaction using the names of the substances involved.
a) Word equation:
Sodium chloride + electrolysis → Sodium hydroxide + Hydrogen gas, Chlorine gas
b) The following reactions take place during the electrolysis of brine solution :
NaCl =
=
Now there are two cations and two anions which get discharged in the following way :
At cathode :
= 
At anode:
=
The remaining ions
= NaOH
That's why we get
,
and NaOH.
c) Balance each equation is:
2NaCl (l) → 2Na(s) +
(g)

Physical properties help identifying a substance and how it changes.
For example: if a substance crushes easily that means it has a low density, but if it’s hard and doesn’t crush easily, that means it has a strong high density.
And eventually the substance would not end up forming a new substance.
Look at the picture below to understand more about physical changes.
Answer:
the volume of 50.2 grams of co2
would simply be
50.2÷48
