Answer:
Explanation:
Hello,
In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:
Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:
Best regards.
Competition is most likely to occur between two organisms. When the organisms interfere with each others resource or when organisms interfere with each others reproduction which will cause the others life to be in short or danger.
Answer:
Zn(s) + Fe(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Fe(s)
Explanation:
When metal zinc is added to an iron (II) nitrate solution, we can see the following redox reaction:
Zn(s) + Fe(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Fe(s)
Zinc is oxidized since its oxidation number increases from 0 to +2.
Iron is reduced since its oxidation number decreases from +2 to 0.
Answer:
Dehydration Reaction
Explanation:
Alcohols can be converted into Alkenes using catalytic amounts of acids as a catalysts.
The water molecule is removed hence, it is called as dehydration reaction.
The reaction is attached.
