Hey :)
In a parallel circuit, a different amount of current flows through each parallel branch of the circuit.
In the series circuit, different voltage exists across each component in the circuit.
Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
Hope this helps :)
Answer:
101.3 kPa / 1 atm (first choice)
Explanation:
1 atm = 101.3 kPa, so to convert atm to kPa, just multiply the given value by 101.3 kPa.
Hope this helps
I’m sorry but I did not understand the question
Answer : The activation energy for the reaction is, 51.9 kJ
Explanation :
According to the Arrhenius equation,
or,
![\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]](https://tex.z-dn.net/?f=%5Clog%20%28%5Cfrac%7BK_2%7D%7BK_1%7D%29%3D%5Cfrac%7BEa%7D%7B2.303%5Ctimes%20R%7D%5B%5Cfrac%7B1%7D%7BT_1%7D-%5Cfrac%7B1%7D%7BT_2%7D%5D)
where,
= rate constant at 295 K
= rate constant at 305 K = 
Ea = activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature = 295 K
= final temperature = 305 K
Now put all the given values in this formula, we get:
![\log (\frac{2K_1}{K_1})=\frac{Ea}{2.303\times 8.314J/mole.K}[\frac{1}{295K}-\frac{1}{305K}]](https://tex.z-dn.net/?f=%5Clog%20%28%5Cfrac%7B2K_1%7D%7BK_1%7D%29%3D%5Cfrac%7BEa%7D%7B2.303%5Ctimes%208.314J%2Fmole.K%7D%5B%5Cfrac%7B1%7D%7B295K%7D-%5Cfrac%7B1%7D%7B305K%7D%5D)
Therefore, the activation energy for the reaction is, 51.9 kJ
K⁺ has positive charge, the easiest way to form a bond is to connect to negatively charged ion. We have only one negative ion Cl⁻.
So, the answer is
C. Cl⁻.
