Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.
A chemical reaction is said to have occurred when new substances are formed. The reaction between magnesium chloride solution and sodium carbonate solution is a double decomposition reaction since the cations exchange anion partners in the product;
MgCl2(aq) + Na2CO3(aq) ------> MgCO3(s) + 2NaCl(aq)
We must note that a single replacement reaction depends on the relative positions of metals in the electrochemical series. Al can react with CuCl2 because Al is more reactive than copper and ahead of Cu in the electrochemical series. On the other hand, Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

Answer:
The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.
Answer:
1) Complete combustion have enough oxygen present to produce carbon dioxide while incomplete combustion doesn't have enough oxygen
2) Complete combustion formula is:<u> </u><u>fuel+( plenty) oxygen--->Carbon-dioxide+</u>
<u>water while incomplete combustion is = Fuel+oxygen--->carbon monoxide+ water.</u>
