Answer:
2000J
Explanation:
Given parameters:
Heat of fusion = 80J/g
Mass of substance = 25g
Unknown:
Amount of energy required to melt the given mass = ?
Solution:
To solve this problem, the amount of energy required to melt the substance is given as;
H = m L
m is the mass
L is the heat of fusion
Insert the given parameters and solve;
H = 25 x 80 = 2000J
The physical properties of a compound are similar to those of its elements.
None. Ammonium has no <span>π bonds at all so it can't have any resonance. </span>
Answer : The balanced chemical reaction will be:
Explanation :
Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.
It is represented as,
In this reaction, A is more reactive element and B is less reactive element.
As per question, when gold (IV) iodide react with bromine to give gold (IV) bromide and iodine.
The balanced chemical reaction will be:
2K + Br₂ = 2KBr
