Matte because it is harder to take off
Answer:
0.35 g Li
Explanation:
H2SO4 + 2Li -> Li2SO4 + H2
7 g Li -> 2 g H2
x -> 0.10 g H2
x= (0.10 g H2 * 7 g Li)/ 2 g H2 x= 0.35 g Li
Molarity is defined as number of moles of the solute in 1 liter of solution.
Molarity = Moles of solute (mol) / Volume of the solution (L)
moles of KCl = mass (g) / molar mass (g/mol)
= 10.0 g / 74.5 g/mol
= 0.134 mol
Hence molarity = 0.134 mol / 0.500 L
= 0.268 mol/L
You have to balance out those forces and apply the same amount of equal and opposite force to it. I hope I helped ^^
