I can if you give man example I'll show you how to do it.
Answer:
1 is b and 2 is d
Explanation:
because you do not know that the cat had done that you was just thinking it was the cat
Answer:
I think its D
Explanation:
It cant be B or C bc the solute particles arent changing. And its not A because the concentration isnt constant
Answer:
Explanation:
Heat involved Q = mcΔt where m is mass , c is specific heat of water and Δt is rise in temperature
= 150 x 4.18 x 25.8 J .
= 16176.6 J .
As the temperature rises , the reaction is exothermic.
Explanation:
Chemical reaction equation for the give decomposition of is as follows:.
And, initially only is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,
= 0.23 aatm
So, = 2.3 - 2(0.23)
= 1.84 atm
Now, expression for will be as follows.
=
= 0.0224
or,
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is .
