Uses Of Periscope
It is used in submarines to determine the distance of a torpedo and helps in deciding the right time for the attack.
It is used in a nuclear reactor to observe the chemical reactions that are taking place.
In military periscopes are used to observe from their hiding position. Hi
Answer:
The answer of question is below.
Explanation:
Hydrolysis means lysis of a molecule using water, then a molecule will form 2 because it will react with water or water will be part of a new molecule.
If water reacts with a polymer, depends on the kind of polymer the products:
If water reacts with alkenes or alkynes, water will attach to the double or triple bond and the products will be an alcohol or a ketone.
If water reacts with an ester, the products will be 2 alcohols.
Answer:
Explanation:
a. the salt produced would be Mg3N2(magnesium nitride)
b. magnesium loses 2 electron to form Mg2+ ion and nitrogen gains 3 electron to form n3-
when several of these ions come together 3 Mg2+ ion combine with 2 n3- ion to form Mg3N2 thus Mg getting six electron from nitrogen to form a ionic bond.
c. the reaction is not balanced Mg + N2 = Mg3n2
to make it balanced the reaction should be 3 Mg + N2 = Mg3N2.
the reaction was not balanced before because the number of Mg on both side of the reaction was not equal.
d. magnesium nitrate has formula Mg(NO3)2 is formed when Mg combines with nitrogen and oxygen Mg + N2 + o2
Answer:
form the Octet Rule
Remember that the Octet Rule allows all atoms to get 8 valance electrons either by gaining or losing electrons (except for Hydrogen and Helium because of the Duet Rule who allows to get no more that 2 valance electrons)
