Answer:

Explanation:
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
From the reaction given that:-

The expression for the rate is:-
![r=k[P]^2](https://tex.z-dn.net/?f=r%3Dk%5BP%5D%5E2)
Given that;- k=
/Ms
[P] =
M
Thus,

Water is known as a life-giving liquid because every living organism depends on the water for its survival.
<h3>Journal about the topic Water-The Life Giving Liquid</h3>
Water is also called a life-giving liquid because without water life on earth is not possible. All other living organisms need to consume water to survive and grow in size. We need water for many other activities such as cleaning, washing, cooking and irrigation. Water is essential for all living things including humans, animals and plants. Water is called wonder liquid as it can dissolve large number of substances. This property enables water to be a great solvent. Most of the chemical reactions of the living world is carried out in water as a medium so that's why water is known as Life Giving Liquid.
So we can conclude that Water is known as a life-giving liquid because every living organism depends on the water for its survival.

Answer: -
0.1 ml of bleach should be added to each liter of test solution.
Explanation:-
Let the volume of bleach to be added is B ml.
Density of stock solution = 1.0 g/ml
Mass of stock solution = Volume of stock x density of stock
= B ml x 1.0 g/ml
= B g
Amount of NaOCl in this stock solution = 5% of B g
=
x B g
= 0.05 B g
Now each test solution must be added 5 mg/l NaOCl.
Thus each liter of test solution must have 5 mg.
Thus 0.05 B g = 5 mg
= 0.005 g
B = 
= 0.1
Thus 0.1 ml of bleach should be added to each liter of test solution.
Answer:
0.479 M or mol/L
Explanation:
So Molarity is moles/litres of solution...often written as M=mol/L
So here we are given grams of BaCl2 which we have to convert to moles. To convert to moles of BaCl2 we have to divide 63.2 g BaCl2 by molar mass of BaCl2 which is 208.23 g/mol so you get 63.2/208.23 = 0.3035 moles of BaCl2
Second step is converting the 634mL to litres by simply dividing by 1000 because we know 1 litre has 1000ml so 634/1000 = 0.634L
Now we just plug these guys in our molarity formula M=mol/L
M= 0.3035/0.634 = 0.479 M or mol/L
Answer:
True
Explanation:
In pi bonds, the electron density concentrates itself between the atoms of the compound but are present on either side of the line joining the atoms. Electron density is found above and below the plane of the line joining the internuclear axis of the two atoms involved in the bond.
Pi bonds usually occur by sideways overlap of atomic orbitals and this leads to both double and triple bonds.
