Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed
spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.
The balanced chemical formula would be:
2Mg + O2 = Mg2O2
Answer : The rate of formation of is,
Explanation : Given,
Rate of disappearance of =
The given rate of reaction is,
The expression for rate of reaction :
From this we conclude that,
Now put the value of rate of disappearance of , we get:
Therefore, the rate of formation of is,
True
water will turn into hydrogen and oxygen gas when electrified
Answer:
you differentiate to find the derivative
