Answer: Reaction A: pi + glucose ⇒ glucose-6-phosphate + H2O ΔG = 13.8 kJ/mol
Reaction B: pi + frutose-6-phosphate ⇒fructose-1,6-biphosphate + H2O ΔG = 16.3kJ/mol
Explanation: ΔG is the representation of the change in Gibbs Free Energy and relates enthalpy and entropy in a single value, which is:
ΔG = ΔH - TΔS
where:
ΔH is enthalpy
T is temperature
ΔS is entropy (measure of the )
It can also predict the direction of the reaction with the conditions of temperature and pressure being constant.
When the change is positive, the reaction is non-spontaneous, which means the reaction needs external energy to occur. If the change is negative, it is spontaneous, i.e., happens without external help.
Analyzing the reaction, we see that reaction A and B have a positive ΔG, while reaction C is negative, so the reaction that are unfavorable or nonspontaneous are <u>reactions A and B</u>.
7000m is the answer as 1 km is 1000m ...so 7km multiplied by 1000m u get 7000 m...and always remember if u r converting a bigger unit to a smaller unit u multiply and if u r converting a smaller unit to a bigger unit u divide
Answer:
Chemical reaction.
Step-by-step explanation:
In the experiment, a catalyst is added to concentrated hydrogen peroxide.
The hydrogen peroxide <em>decomposes</em> rapidly, according to the equation
2H₂O₂(ℓ) ⟶ 2H₂O(ℓ) + O₂(g)
New substances are formed, and old ones disappear, so this is a chemical reaction.
The reaction also releases a <em>large amount of heat</em>.
The rapidly-expanding oxygen gas caries with it droplets of water and hydrogen peroxide (and probably some steam, as well).
The visual effect is like a genie escaping from its bottl<em>e</em>.
