38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.
Answer:
Because it uses the residual energy of the fluid used by the first engine.
Explanation:
A combined cycle power generation counts with two heat engines that work in tandem from the same source of heat. The engines turn the energy into mechanical energy.
The cycle is much more efficient than the other, almost 60% more.
I hope this answer helps you.
I am sorry but do not listen to the link above it is a virus and it will be installed if you do stay safe and spread the word
I really don’t know the answer, please help this kiddo with his question
Answer: Option (A) is the correct answer.
Explanation:
Chemical equation for the given reaction is as follows.
And, the expression to calculate pH of this reaction is as follows.
pH = ![pk_{a} + log \frac{[HCOO^{-}]}{[HCOOH]}](https://tex.z-dn.net/?f=pk_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5BHCOO%5E%7B-%7D%5D%7D%7B%5BHCOOH%5D%7D)
As the concentration of 
is directly proportional to pH. Hence, when there occurs a decrease in the pH of the solution the ![[HCOO^{-}]](https://tex.z-dn.net/?f=%5BHCOO%5E%7B-%7D%5D)
will also decrease.
Thus, we can conclude that the statement, HCOO will accept a proton from HCl to produce more HCOOH and 
, best supports the student's claim.
