2 or more simple machines I hope this help :)
Answer:
Decrease temperature with increase in ammonium nitrate concentration.
Explanation:
The temperature changes when different masses of ammonium nitrate are dissolved in water because the ammonium nitrate takes energy from the surrounding water environment for the breaking of ionic bonds as a result the temperature of water decreases. When more concentration of ammonium nitrate is added to water, more decrease occur in temperature of water and the water becomes cold.
Answer:
Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
Explanation:


The substance having highest positive reduction
potential will always get reduced and will undergo reduction reaction.
Reduction : cathode
..[1]
Oxidation: anode
..[2]
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the
of the reaction, we use the equation:


The overall reaction will be:
2 × [1] + 3 × [2] :

Electrons on both sides will get cancelled :

Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
If you are in the zone, you are happy or excited because you are doing something very skilfully and easily.
The answer
the main formula is given by
Q=mSDT
where m= mass
s= specific heat
DT= <span>change in temperature
so Q = 50.89 x 1.8x 4.11 = 376.48</span>
