Answer:
the D
Explanation:
The metal ice-cube tray has a higher conductivity
Answer:
Si ha mirado una tabla periódica, es posible que haya notado que la masa atómica de un elemento rara vez es un número par. Dupdo
Un Dalton, también conocido como unidad de masa atómica, es aproximadamente la masa de un solo protón o neutrón. Dupdo
Es decir, el deuterio tiene el doble de masa atómica que el protio y el tritio tiene tres veces la masa atómica del protio. Dupdo
El número bariónico, que es equivalente al número de masa atómica, debe permanecer constante para que se produzca una reacción.
Explanation:
Explanation:
According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
As the given reaction is as follows.
(a) When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.
Thus, formation of 
will increase.
- (b) When we decrease the volume (at constant temperature) of given reaction mixture then it implies that there will be increase in pressure of the system. So, equilibrium will shift in a direction where there will be decrease in composition of gaseous phase. That is, in the backward direction reaction will shift.
Hence, formation of will decrease with decrease in volume.
- When we increase the mount of
then equilibrium will shift in the direction of decrease in concentration that is, in the forward direction.
Thus, we can conclude that formation of will increase then.
Answer:
A) The reaction is exothermic reaction
B) 46 gm CH3CH2OH = 1236KJ
15.3 gm ch3ch2OH = 1236/46 x 15.3
= 411.10 KJ..........released
therefore 1 KJ = 0.239 K cal
so, 411.10 x 0.239 kcal
= 98.2529 .................. released
c) 54 gm of H2O produced = 1236KJ
so, 42.7 gm H2O produced = 1236/54 x 42.7KJ
= 977.35 KJ released.

I took the test I think the guy above is correct I’m not to sure good luck thanks
