Answer:
Explanation:
Ca₃( PO₄)₂ = 3 Ca⁺² + 2 PO₄⁻³
x 3x 2 x
Let solubility be x mole per litre
solubility product = (3x )³ x ( 2x )²
= 108 x⁵ = 1.2 x 10⁻²⁹
x⁵ = .0111 x 10⁻²⁹ = .111 x 10⁻³⁰
x = .64 x 10⁻⁶ moles / litre
Answer:
One of the main functions lipids do is storing energy.
provide the building blocks for muscle tissue
The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. ... The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid.
<span>Li ----> Li+ + e-(oxidation)
now comes </span>
<span>Reduction: </span>
<span>H2 + 2e- ------> 2H
now by
</span>Multiplying (1) by 2 and adding in (2) will give you the required equation..
..
<span>2Li + H2 ---------> 2LiH
</span>half reaction are either oxidation or reduction
Answer:
False
Explanation:
Chemical reaction equation:
C₅H₁₂ + 8O₂ → 2CO₂ + 6H₂O
Most chemical reactions obey the law of conservation of mass. By so doing, the number of chemical elements on both sides of the expression must be balanced.
Reactants Products
C 5 4
H 12 12
O 16 10
We see that for C and O, the number of atoms on both sides of the expression differs and so, it is not balanced.
