Answer:
50 mL
Explanation:
In case of titration , the following formula is used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = 0.50M
V₁ = 100 mL
M₂ = 1.0M
V₂ = ?
Using the above formula , the volume of base , can be calculated as ,
M₁V₁ = M₂V₂
substituting the respective values ,
0.50M * 100 mL = 1.0M * V₂
V₂ = 50 mL
Answer: -
The temperature change for water in the 4-liter container will be
a.half that of the 2-liter container.
Explanation: -
The increase in temperature of a substance when heat is given to it is given by the formula
Q = m x c x ΔT
Where Q is the heat supplied, m is the mass of water, c is the specific heat of water and ΔT is the change in the temperature of water.
Or ΔT =
From the formula we see that for the same amount of heat, increase is temperature is more for less amount of mass.
We know that more the volume of water, more the amount of water present and consequently more the mass of water.
Thus for the same amount of heat supplied, the temperature increases more for a lesser volume of water.
Let density of water be d.
Mass of 4 L= volume x density = 4 L x d
T 1 = ΔT for 4 L =
=
Mass of 2 L= volume x density = 2 L x d
T2 = ΔT for 2 L =
=
On taking ratio
= 2
Thus the temperature change for water in the 4-liter container will be
a.half that of the 2-liter container.
Answer:
750 newtons
Explanation:
newtons law stats that anything in motion stays in motion unless intervene. friction tends to do that for u but if there is no friction it should have the same force it started with
