The hydrogen and oxygen<span> atoms from H</span>₂O are <span>bonded together through covalent </span>bonding.
Ca(OH)₂: strong base
pOH = a . M
a = valence ( amount of OH⁻)
M = concentration
Ca(OH)₂ ⇒ Ca²⁺ + 2OH⁻ (2 valence)
so:
pOH = 2 x 0.005
pOH = 0.01
pH = 14 - 0.01 = 13.99
The scientist's results is that at a temperature of 35<span>°C, the solubility of the substance in water is 146.2 grams in 200 grams of water. There isn't really a different method to determine the solubility of a substance in water. Another procedure could be that a lesser amount of the substance is used and the water required to dissolve it is determined. The solubility of the substance based on the two procedures can then be compared.</span>
Hello!
The correct answer is 1. KCI.
I really hope this helped you out! c:
Answer:
The line drawn through points D and E.
Explanation:
Y is a horizontal line and D and E are both on the same line. If a line were drawn it would be within the Y plane.
