Answer: (C) Dissolution is the process by which a solute form a solution in a solvent.

Explanation: Dissolution can be described as the process by which a solute dissolves in a solvent to give a solvent.

The solute may be a solid, liquid or gas and solvent is usually a liquid but can also be liquid, gas or supercritical fluid. The most common solvent is water and it is referred to as the universal solvent.

Example are:

1.Stirring of sugar in water.

In this case the solute is the sugar and the solvent is water.

2.Organic substances dissolves readily in solvent like kerosene and benzene and they are known as non-polar solvent while the organic substances are the solute

Setler79 [48]

Answer:

192g

Explanation:

so for this find out there moles of CH4 by moles=mass/mr

48/16=3 then use molar ratio 1:2 so times it by 2 which is 6 moles. then uses mass =moles*mr so 6*32=192g is the answer hope this helps to understand.

Use the given molar solubilities in pure water to calculate ksp for each compound. part a bacro4; molar solubility =1.08×10−5m
Margaret [11]
<span>When BaCrO4 dissolves, it dissociates like this: BaCrO4 (s) --> Ba2+ + CrO42-
</span>
<span>The expression for Ksp is [Ba2+] x [CrO42-]
</span>
There is a 1:1 molar ratio between the BaCrO4 that dissolves and Ba2+ and CrO42- that are in solution. This means that, when 1.08×10⁻⁵ moles per liter of BaCrO4 dissolves, it produces 1.08×10⁻⁵ mol/L of Ba2+ and 1.08×10⁻⁵ of  <span>CrO42-. So, applying the expression:
</span>
Ksp = (1.08×10⁻⁵ ) x (1.08×10⁻⁵ )
= 1.166 x 10⁻¹⁰

The combustion of ammonia produces NO and water. If the chemical reaction for this process is properly balanced using the smalle
cestrela7 [59]

Answer:

10

Explanation:

The unbalanced combustion reaction is shown below as:-

NH_3+O_2\rightarrow NO+H_2O

On the left hand side,  

There are 3 hydrogen atoms and 1 nitrogen atom and 2 oxygen atoms

On the right hand side,  

There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms

Thus,  

Right side, H_2O must be multiplied by 6 to balance hydrogen.

Left side, NH_3 must be multiplied by 4 to balance hydrogen.

Also, Right side, NO is multiplied by 4 so to balance nitrogen.

Left side, O_2 must be multiplied by 5 to balance the whole reaction.

Thus, the balanced reaction is:-

4NH_3+5O_2\rightarrow 4NO+6H_2O

Sum of Coefficient of product - 4 + 6 = 10

CH3CH2PH2 can be synthesized by an SN2 reaction. Draw the structures of the alkyl chloride and nucleophile that will give this c
Maru [420]

Answer:

The PH2 becomes attached to the alkyl halide with inversion of configuration

Explanation:

SN2 reaction involves the simultaneous attachment of the nucleophile as the leaving group departs. This leads to an inversion of configuration because the sterochemistry around the carbon bearing the leaving group is reversed. The reaction proceed via a crowded five coordinate transition state. Details are shown in the image attached.
