Answer:
Explanation:
In spontaneous reaction , there is decrease in Gibb's free energy .( Δ G is negative ). Out of given reaction , following reactions have negative Δ G so they are spontaneous.
C ₂ H ₄ + H ₂ Rh ( I ) −−−→ C ₂ H ₆ , Δ G = − 150.97 kJ / mol
C ₆ H₁₃O₉ P + ATP ⟶ C ₆ H₁₄ O₁₂ P₂ + ADP , Δ G = − 14.2 kJ / mol
Answer:
True
Explanation:
A proton has a charge of +1, while an electron has a charge of -1. This is why a neutral atom has the same number of protons as electrons.
Neutrons have no charge, hence their name neutron which is similar to neutral.
Answer:
Nuclear Fission is a nuclear reaction or a Radioactive decay progress in which the necleus of an atom splits into two or more smaller, lighter neclei
Answer:
K^+ and NO3^-
Explanation:
In a balanced ionic equation, we usually see the species that react to yield the main product in the reaction.
Consider the reaction;
Pb(NO3)2(aq) +2 KI(aq) -------> PbI2(s) + 2KNO3(aq)
The main product in this reaction is PbI2. Hence the balanced ionic equation is;
Pb^2+(aq) + 2I^-(aq) ------> PbI2(s)
Notice that K^+ and NO3^- did not participate in this reaction. All ions that are part of the molecular equation but do not participate in the ionic reaction equation are called spectator ions. Hence K^+ and NO3^- are spectator ions in this reaction as can be seen clearly above.
