<span>The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.
This means that for example, when you're bag has a mass of a 1kg, and you filled it with clothes it will jump its mass from 1kg to possibly 5kg, hypothetically. Thus, withoout the object or clothes that was added the weight of the bad wouldn't change and vice-versa.

Answer:
The following reaction will occur at cathode:
Explanation:
The two half reaction during electrolysis of aqueous nickel sulfate will be
a) anode reaction :
Water will undergo oxidation and will evolve oxygen gas at anode as shown in the given reaction:
b) Cathode reaction: The reduction of Nickel ion will occur by gain of two electrons as shown in the given equation:
Thus the overall reaction will be:
30 degrees from the mirror's surface
pretty sure It's correct and if it is then your welcome
Answer:
My best bet would be A) The stars to form
learned about this is in 7th grade
Explanation:
If reactants eventually collide,
there is an occurrence of reaction.
<span>
Therefore, when there is an increase concentration of
reactant, meaning to say that there are several moles of it every unit volume. An
example of this is a room having hundred of people will absolutely get higher
concentration compared to a room with one individual only.
Pertaining to effective collisions, if ever there is an
increase of concentration, the frequency and rate of effective collisions among
reactants surges in such a way that the rate of reaction also surges. Same with
passing into a room with only 1 individual compared to hundred people blind
persons, you probably want to proceed to the room with several people.</span>
<span>This is the simple logic
behind that scientific existence.</span>
