Answer:
Explanation: Don't let anyone bring you down you got this you matter, and rock!
Mechanism. 1) Nucleophilic Attack by the Alcohol. 4a.jpg. 2) Deprotonation by pyridine. 5a.jpg. 3) Leaving group removal.The esterification reaction is both slow and reversible. The equation for the reaction between an acid RCOOH and an alcohol R' OH.
Alrighty, so, imagine you didn't or don't know much about desertification. You could imagine that it means the land becomes a desert. Knowing this I think it's easy to assume that desertification makes it harder for people in Southeast Asia to grow food or even build houses once their natural resources are destroyed from desertification.
Answer: Option C) 4 moles
Explanation:
The reaction below shows the decomposition of 2 moles of water to yeild 2 moles of hydrogen and 1 mole of oxygen respectively.
2H2O(l) --> 2H2(g) + O2 (g)
So, if 2 moles of H2O produce 1 mole of O2
8 moles of H2O will produce Z mole of O2
To get the value of Z, cross multiply
2 x Z = 1 x 8
2Z = 8
Z = 8/2
Z = 4
Thus, 4 moles of O2 is produced from the complete decomposition of 8 moles H2O .
In chemistry, there is a common note that says, "Like dissolves like".
This pertains to the concept that polar substances can dissolve only other polar substances. Also, nonpolar substances are also only able to dissolve nonpolar substances.
Polarity of the substance depends primarily on the type of bond and the difference in electronegativity.
Water is a polar substance while vegetable oil is not. From the concept presented above, it may be concluded that water will not be able to dissolve the vegetable oil and the assumption is logical.
