Gibbous refers to the moon when it is more than half full but not completely full. This results in half a circle with a smaller arc on the opposite side. This makes a weird shaped “hump” on that side which is what the humpback means.
The correct answer is option D, that is, two new compounds.
Double displacement also known as double replacement reactions, metathesis or exchange reactions. It take place when two ionic compounds are exchanged forming two new compounds. One can consider the reaction as swapping the anions or the cations.
Water usually functions as the solvent for a double replacement reaction, and the products and reactants are generally ionic compounds, however, they can also be bases or acids. The example of a double replacement reaction is:
BaCl₂ (aq) + Na₂SO₄ (aq) = BaSO₄ (s) + 2NaCl (aq)
In this, the cations are Na⁺ and Ba²⁺, and the anions are SO₄²⁻ and Cl⁻. If the anions or cations are swapped, the products obtained are BaSO₄ and NaCl.

Explanation:
Answer:
32.73%
Explanation:
To solve this problem, first find the molar mass of Al(OH)₃.2H₂O
Atomic mass of Al = 27g/mol
O = 16g/mol
H = 1g/mol
Molar mass = 27 + 3(16 + 1) + 2(2(1) + 16)
= 27 + 51 + 36
= 114g/mol
Percentage composition = 
x 100 = 32.73%
Answer: determines the age of sample Carbon-14 is used in radiocarbon dating and radiolabeling. Medically important, a radioactive isotope is carbon-14, which is used in a breath test to determine the ulcer-causing bacteria Heliobacter pylori
The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon-14 activity in modern and background samples.
