In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
spanish:
En física y química, la ley de conservación de la energía establece que la energía total de un sistema aislado permanece constante; se dice que se conserva con el tiempo.
Answer: Therefore, the volume of 0.001 M KI is 61 ml.
Explanation:
The balanced chemical reaction is :
![2KI+Cu(NO_3)_2\rightarrrow CuI_2+2KNO_3](https://tex.z-dn.net/?f=2KI%2BCu%28NO_3%29_2%5Crightarrrow%20CuI_2%2B2KNO_3)
According to the neutralization law,
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
= molarity of
solution = 0.100 M
= volume of
solution = ?
= molarity of
solution = 0.200 M
volume of
solution = 15.25 ml
= valency of
= 1
= valency of
= 2
Putting in the values we get:
![1\times 0.100\times V_1=2\times 0.200\times 15.25](https://tex.z-dn.net/?f=1%5Ctimes%200.100%5Ctimes%20V_1%3D2%5Ctimes%200.200%5Ctimes%2015.25)
![V_1=61ml](https://tex.z-dn.net/?f=V_1%3D61ml)
Therefore, the volume of 0.001 M KI is 61 ml.
Answer:
H3O+
(aq) (the hydronium ion)
whereas weak acids dissociate only partially in water.

Answer:
the molecules strike the walls of the container more often.
Explanation:
The pressure of a gas refers to the force per unit area exerted on the walls of container by gas molecules.
Since the average kinetic energy of gas molecules increases as the temperature of the gas increases, the molecules of the gas tend to strike the walls of the container more often as the temperature of the gas increases.
Hence, the pressure of a gas increases due to an increase in temperature because the gas molecules strike the walls of the container more often.
To answer this lets first see how much 1 kg is equal to in cg.
1 kg = 100000 cg
Now lets multiply:-
100000 × 1.7 = <span>170000
</span>
So, 1.7 kg = <span>170000 cg
</span>
