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
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Answer: The correct answer is in an exothermic reaction the energy of the product is less than the energy of the reactants.
Explanation: got it
Answer:
The answer to your question is A. Decomposition
Explanation:
In the picture, we can observe that there is only one reactant that after the reaction are formed two products.
We observe that this is a decomposition reaction.
It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.
In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.
