Atoms cannot be subdivided into smaller particles - incorrect as you can subdivide atoms into protons, neutrons and electrons
PV = nRT —> n = PV/RT
P = 2.90 atm
V = 4.80 L
R = 0.08206 L atm / mol K
T = 62.0 + 273 = 335 K (make sure you convert from celsius to kelvin)
n = (2.90 • 4.80) / (0.08206 • 335) = 0.506 moles of gas
Answer:
12.044 x 10^23 atoms Na
Explanation:
1 mol Na has 6.022 x 10^23 atoms of Na
2 moles Na have 2 x NA = 2 x 6.022 x10^23 atoms Na
When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution. So, any answer with “as surface area increases, solid dissolves faster” would be correct. :)
Well it depends on how long you let it boil, if it boils for a long time then the water levels will slowly decrease, if u let it sit for a while you can drink it.
