Usually a ball would roll toward the side that's lower, so if you had a ramp and put it on the side that was lower, then the ball would change direction and go the opposite direction
1) Molarity
M = n / V
n: number of moles of solute
V: volume of the solution in liters
n = mass / molar mass = 0.000333 g / 332.32 g / mol = 1*10 ^ - 6 moles
V = 225 ml * 1 liter / 1000 ml = 0.225 liter
M = 10^-6 mol / 0.225 liter = 0.00000444 M
2) ppm
ppm = parts per million
grams of solute: 0.000333 g
grams of solution = volume * density = 225 ml * 0.785 g / ml = 176.625 g
ppm = [0.00033 g / 176.625 g] * 1,000,000 = 1.868 ppm
Answer:
6 moles of electrons are transfered
Explanation:
The actual redox is
S4+ +6e- long arrow S2- + 3O2
From the reaction, addition of 6 electrons on the LHS is needed to balance the electron number, hence 6 moles of electrons are transfered
Answer:
24 meters
Explanation:
24 meter because area
area=Lxw
so just multiply 4 x 6 = 24
