Answer:
0.4515 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 10.0 mL
M₂ = 0.100 M
V₂ = 45.15 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 10.0mL = 0.100 M * 45.15 mL
M₁ = 0.4515 M
Hence, the concentration of the acetic acid = 0.4515 M
Answer: 5.44×10226.022140857(74)×1023⋅mol−1.
Explanation: So the answer is approx. 0.10⋅mol
Answer:
The answer to the question is
<h2>
A. Air, Soil, Sand, Water</h2>
Explanation:
Answer: B. ΔH < 0, ΔS > 0, and ΔG < 0
Explanation:
Exothermic reactions are those in which heat is released by the system and endothermic reactions are those in which heat is absorbed by the system.
for Exothermic reaction is negative and for Endothermic reaction is positive.
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
When NaOH is dissolved into water, the molecules change their state from solid to aqueous and thus randomness increases. The beaker becomes warm means the reaction is exothermic
is positive and is negative Using Gibbs Helmholtz equation:
Thus 
will be negative.
Thus is positive, is negative and will be negative.
