Answer:
6) solid- dots close together
liquid- a little bit farther apart than solid
gas- far apart
7) the movement of anything from a higher area of concentration to an area of lower concentration.
8) B. evaporation
9) The solute is the thing being dissolved, the solvent is the thing dissolving it, and the solution is the product of the solute and solvent.

*I'm not exactly sure on #10 but I hope I could've helped a little at least
I calculated is and the answer is 1272.0600000000002.
I really don't know how to explain it
Answer:
1. 0.35 moles NaOH
2.
moles 
3. 505.4 g Pb
4. 1.46 g HCl (if that is wrong it's 1.5 g HCl due to sig figs)
5.
atoms of Ag
6.
atoms of Cu
Explanation:
1. The mass of NaOH is 40g. 22.99(Na)+16(O)+1.01(H)=40 g
14 g NaOH *
= 0.35 moles of NaOH
2. Mass of
0.05 g
×
3. mass of Pb = 106.4 g
4.75 moles Pb×
4. mass of HCl = 1.01 +35.45 = 36.36 g
0.04 mol HCl x 
5. 5.00 mol Ag x
6.
Cu x
atoms of Cu
Answer:
Helium does not react with any element
Please find the explanation below
Explanation:
Helium (He) is an element in group 8A of the periodic table, which is a group of element referred to as NOBLE GASES. Other elements in this group are Xenon (Xe), Krypton (Kr), Neon (Ne) etc.
One major characteristics of Helium and other Noble gases that makes them so UNREACTIVE is that they have a full electronic configuration i.e. they have a full electron shell and do not share electrons with any element, which is the basis of REACTING. For this reason, Helium will not react with any element.
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy
