Answer:
Explanation:
Hello!
In this case, when writing net ionic equations, we first need to identify the complete molecular equation; thus for potassium dichromate reacting with copper (I) bromide, we have:
Thus, since all the species are aqueous except copper (II) dichromate, we can write the complete ionic equation by ionizing the aqueous ones:
Finally, for the net ionic equation, we need to cancel out the spectator ions as they are present at both reactants and products sides, thus, we obtain:
Best regards!
I believe that the correct answer here is:
“in neither photosynthesis nor
respiration”
This is because during photosynthesis,
carbon dioxide is converted to glucose.
<span>While during respiration, carbon
dioxide is not split because it is one of the products of respiration hence it
is rather created.</span>
Answer: It is non-spontaneous at all T.
Explanation:
According to Gibb's equation:
= Gibbs free energy = +ve
= enthalpy change = +ve
= entropy change = -ve
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Putting in the values:
Reaction is non spontaneous at all temperatures.
When a molecule loses or gains an electron it becomes an ion.
"If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion."
