Answer:

The incorrect statement from the options is OXIDATION IS A "GAIN" OF ELECTRONS

Explanation:

Oxidation in a redox reaction is the loss of electrons. It is also the increase in the oxidation states of an atom or ion or atoms in a molecule. A redox reaction is a type of chemical reaction in which there is a transfer of electrons from an atom or ion to another resulting in a change in oxidation states of the substances involved. The reducing agent in the reaction is undergoes oxidation by losing electrons while the oxidating agent is reduced that is it gains electrons at the end of the reaction. The atom or ion from which electron is lost is said to be oxidized while the other atom or ion involved in the reaction is reduced.

Oxidation is also the combination with O atoms and it is always accompanied by reduction because oxidation forms a half of the whole redox reaction. A substance cannot be oxidized except it has reduced another substance by losing electrons to it.

Calculate the freezing point of a 0.100 m aqueous solution of k2so4, taking interionic attractions into consideration by using t
Leokris [45]
Ionic  salt  dissociate  completely  in  water   particularly in  water at  low  concentration.
 The  molal  freezing point  of  depression constant  for  water is 1.85kg/k/mol
therefore depression  of  freezing  point =1.853  x 0.100  x  2.32=0.429  degrees  celsius
hence  solute  freeze at - 0.429  degree  celsius

What is the heat of reaction (ΔH°rxn) for the combustion of acetone (C3H6O) given the following thermochemical equations? 1. 3 C
nydimaria [60]

Answer : The enthalpy of combustion of C_3H_6O will be -1775 kJ

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

The combustion of C_3H_6O will be,

C_3H_6O(l)+4O_2(g)\rightarrow 3CO_2(g)+3H_2O(l)    \Delta H_{comb}=?

The intermediate balanced chemical reaction will be,

(1) 3C(s)+3H_2(g)+\frac{1}{2}O_2(g)\rightarrow C_3H_6O(l)     \Delta H_1=-285.0kJ

(2) C(s)+O_2(g)\rightarrow CO_2(g)    \Delta H_2=-394.0kJ

(3) H_2(g)+\frac{1}{2}O_2(g)\rightarrow H_2O(l)    \Delta H_3=-286.0kJ

Now we are reversing the reaction 1, multiplying reaction 2 and 3 by 3 and then adding all the equations, we get :

(1) C_3H_6O(l)\rightarrow 3C(s)+3H_2(g)+\frac{1}{2}O_2(g)     \Delta H_1=285.0kJ

(2) 3C(s)+3O_2(g)\rightarrow 3CO_2(g)    \Delta H_2=3\times -394.0kJ=-1182.0kJ

(3) 3H_2(g)+\frac{3}{2}O_2(g)\rightarrow 3H_2O(l)    \Delta H_3=3\times -286.0kJ=-858.0kJ

The expression for enthalpy of combustion of C_3H_6O will be,

\Delta H_{comb}=\Delta H_1+\Delta H_2+\Delta H_3+\Delta H_4

\Delta H_{comb}=(285.0)+(-1182.0)+(-858.0)

\Delta H_{comb}=-1755kJ

Therefore, the enthalpy of combustion of C_3H_6O will be -1775 kJ

Heating a solution of alcohol and water, then collecting the alcohol vapors and condensing them into a liquid with higher alcoho
Sindrei [870]

Answer:

Distillation.

Explanation:

If we are heating a mixture of two miscible liquids and collecting the vapors it means we are separating the two mixtures from each other based on their boiling point differences.

This technique of separation of two liquids based on the difference in boiling point is known as Distillation.

Alcohol will evaporate easily as compared to water as water has stronger influence of hydrogen bond making the inter-molecular forces stronger.
