Answer:
= 0.014 g of BaCO3
Explanation:
Let x = mol/L of BaCO3 that dissolve.
This will give;
x mol/L Ba2+ and x mol/L CO32-
But;
Ksp = 5.1x10^-9.
Therefore;
Ksp = 5.1 x 10^-9 = (x)(x)
Thus;
x = molar solubility
= √ (5.1 x 10^-9)
= 7.1 x 10^-5 M
Therefore;
Mass BaCO3 = 7.1 x 10^-5 M x 1 L x 197.34 g/mol
= 0.014 g
Answer choice "A. Defrostration " is the only "natural" cause of soil erosion
Answer:
26.0 moles
Explanation:
Given the formula;
PV =nRT
P= pressure of the gas
V = volume of the gas
n = number of moles of the gas
R = gas constant
T = temperature
n = PV/RT
n = 125 * 5/0.082 * (20 + 273)
n = 625/24.026
n = 26.0 moles
It’s absorbed The outer layer of fabric does get hotter because the black color absorbs more heat. And that heat doesn't get transmitted to the skin because of the thick fabric. But thin black clothing transmits that heat to the skin, making a person hotter
