Answer:
The answer to your question: I think is letter c
Explanation:
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
a.- Precipitation: is incorrect because for this kind of reactions one of the products must be a precipitate and in the reaction we see that NAOH is soluble in water (aq) and H2 is a gas, none of them precipitate.
b. acid - base: the reactants must be an acid and a base, and the reactants of this reaction has a base but it's in the products.
c. Redox: This reaction is a redox reaction because for this reaction the oxidation numbers of the reactants must change and this happen in this reaction (H changes from +1 to 0) and Na changes from 0 to +1.
d. Combination. In this reaction the reactants combine to form a new compound and this doesn't happen here.
e. None of the above. is false because letter C is correct.
Answer:
Ph-OH
Explanation:
Nitration of Aromatic compounds is an example for Aromatic Electrophilic substitution and its rate is enhanced by Electron donating group like OMe, OH, alkyl group and halides (least activating group) while reactivity is diminished by electron withdrawing like CN,NO2 and Ketone etc
Hence phenol is more reactive than benzene towards nitration.
Answer:
Carboxylic acids produce hydrogen bonds amongst themselves and possess lower vapor pressure. They generally possess a sour odor. When an acid and a base react with each other to produce salt and water and comprises the combination of hydrogen and hydroxide ions, the reaction is termed the neutralization reaction. Thus, when carboxylic acid reacts with base the reaction is termed neutralization.
On the other hand, esters are known for their pleasant fragrances. They do not produce hydrogen bonds amongst themselves and possess higher vapor pressure. A hydration reaction in which free hydroxide dissociates the ester bonds between the glycerol and fatty acids of a triglyceride, leading to the formation of free fatty acids and glycerol is termed saponification.
Thus, the given blanks can be filled with carboxylic acid, carboxylic acid, esters, esters, esters, and carboxylic acid.
Answer:
D: lose an electron
Explanation:
when an atom loses an electron it's positively charged and when it gain an electron it is negatively charged
