Explanation:
1. Al2(SO4)^3 (aq) + 6LiOH aql) ----> 3Li2SO4 (aq) + 2Al(OH)^3 (s)
2. (NH4)2CO3 (aq) + MgCl2 (aq) ----> 2(NH4)Cl (aq) + MgCO3 (s).
Answer:
The sun
Explanation:
The sun is the primary source of energy in most living communities. The producers or the green plants that prepare their own food by the use of sunlight and other natural resources. Carbon dioxide, water, and other minerals are used by the plants to make their food in the presence of chlorophyll. Plants are then consumed by the consumers. This chain helps in forming the food chain and the food web.
<u>Answer:
</u>
Reaction C
<u>Explanation:
</u>
For reaction A) we have the production of alcohol by the action of the water that attacks the tertiary carbocation produced by the leaving of Br. In the last step we will have the proton transfer (figure 1).
For B) the proton transfer step is given in the double bond formation due to the attack of the hydroxle group (figure 2).
In C we have an Sn2 reaction. Therefore, the reaction takes place in only one step without the opportunity of a proton transfer step (figure 3).
Finally for D we have an elimination reaction in which the tert-butoxide molecule will remove hydrogen (proton transfer step) from the carbocation to produce an alkene (figure 4).
