Answer:contains as much solvent as it can hold
Explanation:
A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. A saturated solution has just the right amount of solute dissolved in it to give a clear solution. More solute will not dissolve after saturation.

Answer:
How high the plants grow in the different soils.
Explanation:
The dependent variable is what happens as a result of what the experimenter changes.
The experimenter could measure how high the plants grow when placed in soil with different pH values.
Covalent bonding is the sharing of electrons between atoms. This bonding occurs primarily between nonmetals. <span>If atoms have similar electronegativities (the same affinity for electrons), covalent bonds are most likely to occur. Because both atoms have the same affinity for electrons and neither has a tendency to donate them, they share electrons in order to achieve octet configuration and become more stable. </span>
Answer:
0.3 moles of H2 will be produced.
Explanation:
Balanced reaction: 2 Al + 6 HCl → 2 AlCl3 + 3 H2
Given Al mass = 5.4 g, we know Mr of Al is 27
Using the formula:
moles = mass / Mr
moles of Al = 5.4 / 27
moles of Al = 0.2 moles
Here we see that "2" molar mass before Al; so in this reaction, "1" molar mass will have [(0.2)/2] = 0.1 moles. He see "3" molar mass before H2, therefore moles of H2 is (3 * 0.1) = 0.3 moles.
