Crystallization is a physical change from liquid form to solid form. It is the opposite of melting. This is done by creating a supersaturated solution. You add more solute exceeding its capacity and heat so that all will dissolve. Then, when you cool it down with an aid of the ice, solid crystals will eventually form. The bigger the container the ice, the faster is the rate of crystallization and the bigger the solid crystals would be.
LiCl
because Li loses 1 electron ==> Li+
and Cl gains 1 electron ==> Cl-
Li+ Cl-
we use the criss cross rule
===> LiCl
Ok I know this did it last year let's see chemical because you can't fix it back to its normal self
Answer: The correct answer is Option 1.
Explanation:
Control group is the group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.
We are given 4 groups which are being experimented for the flotation of an egg in water. As in Cup 1, there is no addition of salt and hence there is no change in the variables. So, this is set as a benchmark fro the cups which are further used in the experiment conducted.
Hence, the correct answer is Option 1.
Answer:
yes
Explanation:
Testing scientific ideas
Testing Ideas. Testing hypotheses and theories is at the core of the process of science. ... match actual results observation, that lends support.
