Answer:
See the explanation below, please.
Explanation:
In redox reactions (oxide reduction) the transfer of electrons between compounds occurs.
In oxidation, electrons are lost (positive charge increases). Example:
Mg ---> Mg2 + + 2 e- (passes from Mg ° to Mg 2+)
On the other hand in the reduction, electrons are gained (negative charge increases or the positive one increases). Example:
Cl2 + 2e- ---> 2 Cl- + 2 e- (passes from Cl ° to Cl-)
The reactants that will form products will be 
.
<h3>Activity series</h3>
Elements at higher positions in the activity series will be able to displace those in lower positions in solutions.
Thus:
because Br is higher than I in the activity series.
Cl cannot displace F in 
because F is higher than Cl in the activity series.
Also, Cl is higher than Br in the activity series, thus, the reaction 
cannot form products.
I cannot displace F, thus, 
cannot form products.

Answer: it has 2 parts
Explanation:
Firstly, plant cells have a cell wall that surrounds the cell membrane, whereas animal cells do not. Plant cells also possess two organelles that animal cells lack: chloroplasts and a large central vacuole
Answer:
Subatomic particles making up an atom
Explanation:
Atom is the smallest unit of any matter
An atom consists of three subatomic particles - Protons, Neutrons, Electrons. Major atomic mass is in the nucleus ie a tiny deep area at the centre. Nucleus consists nucleons, which includes protons (positively charge) & neurons (neutrally charged). Negatively charged electrons are outside the central nucleus.
Answer:
There are five signs of a chemical change:
Colour Change.
Production of an odour.
Change of Temperature.
Evolution of a gas (formation of bubbles)
Precipitate (formation of a solid).
