The binding energy is calculated from the product of the mass defect and the square of the speed of light. First, we need to calculate for the mass defect. We do as follows:
m = mass products - mass of reactantsm = 33*1.00867 + 27*1.00728 - 59.9338 m = 0.54887
E = mc^2 = 0.54887 (3x10^8)^2 = 4.94x10^16 J
The question is incomplete, complete question is:
A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is in calcium ion and in oxalate ion. What will happen once these solutions are mixed?
Answer:
On mixing of both the solutions no precipitation will occur due to lower value of an ionic product of calcium oxalate from its solubility product.
Explanation:
Molar concentration of calcium ions =
Molar concentration of oxalate ions =
ionic product of calcium oxalate in solution :
Solubility product of calcium oxalate =
Generally precipitation occurs when ionic product of substance in solution exceeds its solubility product.
(precipitation occurs)
(non precipitation occurs)
On mixing of both the solutions no precipitation will occur due to lower value of an ionic product of calcium oxalate from its solubility product.
True
Density = mass/volume
Suppose that a block has a mass of 20 g and a volume of 20 cm^3.
Density = 20 g/20 cm^3 = 1 g/cm^3
Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.
The density of the half-block is
Density = 10 g/10 cm^3 = 1 g/cm^3
The density <em>stays the same</em>, even though the size of the sample has changed.
Answer:
one mole of aluminium has reacted in it.
Explanation:
Al : Al2O3=100 gmol-1
4 : 2
2 : 1mol→100g
1 : }50g→1/2mol
