Chlorophyll captures the sun's energy and is used as energy to complete the photosynthesis process
It is insoluble. Because one of the substances are polar and the other is non-polar.
Answer:
I don't have the number of cubes in each bag, but whichever bag had the most cubes would have the most kinetic energy as it falls
Answer:
Al2(SO4)3 and Mg(OH)2
Explanation:
1. Al has a charge of 3-, and SO4 of 2-
when you cross multiply the charges you get
Al2 and (SO4)3
*the reason theres a bracket around the sulfate ion is that the charge 3 is not for oxygen only, but the entire sulphate ion*
Hence, Al2(SO4)3
2. Mg has a charge of 2- and OH of 1-
again cross multiply
Mg (you dont need to add the 1) and (OH)2
again, the bracket around OH means the charge appiles to Oxygen AND hydrogen
hence, Mg(OH)2
