The major visible difference between<span> the two are crystal size, </span>intrusive rocks<span> have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while </span>extrusive rocks<span>, because of the rapid cooling at/above the earth's surface does the opposite. Hope I helped</span>
Answer:
For this experiment we are going to take plate 1 as the control plate, so, in it there will be just E. coli in LB/agar; in plate 2, we are going to put E. coli in LB/agar and some ampicillin. Then, we have to wait for the E. coli colonies to form. After a while, the E. coli growth can be compared on both plates and determine if ampicillin affects or not the E. coli colonies.
Explanation:
If the ampicillin affects negatively E. coli colonies, we are going to observe that in plate 1 (control plate) there are E. coli colonies growing, but in plate 2, there is no E. coli colonies or, at least, there is a fewer number of colonies on it. If ampicillin doesn't affect E.coli, plate 1 (control) and plate 2 (ampicillin experiment) are going to be similar in number of colonies.
Explanation:
To balance a chemical equation implies that we are conserving the number and mass of the reacting species.
Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
This suggests that mass is conserved.
The number of atoms on the reactant side must be equal to that on the product end.
Before proceeding, check the species to see if they have equal number of atoms on both sides:
Fe + CuCI₂ → FeCI₂ + Cu
Elements reactants products
Fe 1 1
Cu 1 1
Cl 2 2
We can see that the equation is already balanced
