Answer:
different from the number of their neutrons
Explanation:
They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
Answer:
The forward reaction is an exothermic reaction.
Explanation:
An exothermic reaction is one in which energy is released, usually in the form of heat hence the enthalpy of the reaction is negative. When a reaction exothermic, the energy of the reactants is greater than the energy of the products hence the excess energy is given out as heat. The reactants lie at a higher energy level in the reaction profile compared to the products.
When we look at the reaction given in the question, NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ , we can easily see from the thermochemical reaction that the forward reaction is exothermic, energy is released by the reaction system as evidenced by the negative enthalpy of reaction.
Given information :
G = 173.3 KJ
H = 180.7 KJ
T = 303.0 K
S = unknown (?)
By using the given formula : G = H - TS , we can calculate the value of 'S'
On rearranging the formula we get : S = 
Plug in the value of G , H and T in the above formula :
S = 
S = 0.02442 
Answer:
Fractional distillation is used for the purification of water as well as separating acetone and water.
Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.
