Given
0.5 M HCl
0.5 M Ca(OH)₂
Required
The concentration
Solution
Molarity from 2 solutions :
Vm Mm = V₁. M₁ + V₂. M₂
m = mixed solution
V = volume
M = molarity
V = mixed volume
1 = solution 1
2 = solution 2
Vm = V₁+V₂
Equal volumes⇒V₁=V₂, and Vm = 2V, then equation becomes :
2V.Mm = V(M₁+M₂)
2V.Mm = V(0.5+0.5)
Mm=0.5 M
Answer:
Explanation:
Gravity:
It is the force by which the elements of matter pulls together.
Explanation:
The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.
The earth is most heavier than all other matter that's why all matter pulls towards the earth.
For example;
when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.
The gravitational force is inversely proportional to the square distance of interacting objects.
As the two objects are more distance apart from each other the less will be the gravitational force.
Answer:
C. 
Explanation:
Molecules with the stronger intermolecular forces are pulled tightly together to form solid at higher temperatures and that's why the freezing point is higher.
Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.
Thus, melting point and boiling point increases with increase in number of carbon atoms and also increase in intermolecular forces (like hydrogen bonding, if present).
Thus, the compound which is gas at room temperature is <u>because it has least number of carbon atoms and absence of hydrogen bonding.</u>
<u></u>
Answer is True. They can in one lifetime by either humans or natural
A reaction is when two or more pure substances combine with each other to form another identity of pure substances. In general from, it is written as:
A + B → C + D
The substances A and B are the reactants, while the substances C and D are the products. Therefore, in a reaction, the products are found at the end or right side of the reaction.
