Aluminum has a molar mass of 27. So one mole of aluminum is 27grams
When CaSO4 → Ca2+ + SO4
So when we have Ksp = [Ca2+][SO4]
when Ksp = 4.93 x 10^-5
and [SO4] = 0.02 M
so by substitution we can get [Ca2+]
4.93x10^-5 = [Ca2+] [0.02]
∴ [Ca2+] = 0.0025 mol/L
∴ the moles of calcium chloride = 0.0025 mol / L * 1.5 L
= 0.00167 mol
Answer:
400 meters every 20 seconds
Explanation:
Remember Tin isn’t Ti, it’s actually Sn and by looking at the periodic table you find it is 118.7 g
A) Temperature does not affect reaction rate
