Hello there!
In this case, according to the solubility equilibrium of calcium hydroxide:
Whereas the equilibrium expression is:
![Ksp=[Ca^{2+}][OH^-]^2](https://tex.z-dn.net/?f=Ksp%3D%5BCa%5E%7B2%2B%7D%5D%5BOH%5E-%5D%5E2)
It is firstly necessary to calculate the molar solubility given the grams and volume of the dissolved solute:
Now, according to the Ksp expression, we plug in s as the solubility to obtain:
Regards!
Answer:
1 . 26
2. 55.854
Explanation:
because atomic number is the number of proton in other words smaller number and the mass number is the number of neutrons and electrons in other words bigger number .
hope this make sense :)
The number of kilograms of fuel that are contained in one canister is 1.03 Kilograms
calculation
mass = density x volume
Density= 0.710 g/cm³
volume = 1.45 L
convert 1.45 l into cm³ to make the units uniform
that is 1 L= 1000 cm³
1.45 L= cm³
by cross multiplication
= (1.45 L x 1000 cm³) / 1 L = 1450 cm³
mass is therefore = 0.710g/cm³ x 1450 cm³ =1029.5 grams
convert grams to Kg
1 kg = 1000 grams
? kg =1029.5 grams
by cross multiplication
= (1 kg x 1029.5 grams) /1000 grams = 1.0295 Kg ≅1.03 kg
A negativley charged ion is the answer
Answer: The Moon can sometimes appear in the sky during the daytime because it is the closest object to Earth, and because its orbital cycle means that sometimes it is brighter in the day than at night.
