The control group is the type of tomato the plants are.
The independent variable is the type of music played.
The dependent variable is Plant A and B's growth.
His conclusion should be that music does not affect the growth of tomatoes.
He should make sure both plants were getting the same amount of water, soil, light, seed, and fertilizer so that can't affect the tomatoes in any way.

Hope this helps!!! Plz mark me!!!! Thx :)
Answer:
RbI<RbBr<RbCl<RbF
Explanation:
As stated in the question, the latice energy depends on the relative size of the ions. When the action size is constant as in the question, the lattice energy now depends on the relative of the anions. The order of increase in ionic sizes among the halide ions is fluoride<Chloride<Bromide<Iodide. This order of increasing size means that the lattice energy will decrease accordingly as shown in the answer.
Following steps are involved in the reaction
Step 1: <span>Cl2(g)⇌2Cl(g)
Step 2: </span><span>Cl(g)+CHCl3(g)→HCl(g)+CCl3(g)
Step 3: </span><span>Cl(g)+CCl3(g)→CCl4(g)
......................................................................................................
Overall reaction : </span>Cl2(g) + CHCl3(g) → HCl(g) + CCl4(g)
Note: Overall reaction is obtained by adding step 1-3 and canceling common terms that are present on reactant and product sides.
The best answer to your question would be B:those who could not be broken down by physical means.
