Which of the following oxide causes acid rain?
CO
NO
H\(_{2}\)O\(_{2}\)
NO\(_{2}\)
Correct answer is D
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents.
The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.
The hydrolysis of proteins by diluting mineral acids produces
sucrose
glucose
amino acids
fatty acids
Correct answer is C
No explanation has been provided for this answer.
The process by which salt and water reacted in a limited way to form an acid or a base is?
Neutral process
Basic acidic process
Hydrolysis
Sublimation
Correct answer is C
- Hydrolysis is any chemical reaction in which a molecule of water breaks one or more chemical bonds.
-Salt hydrolysis is a reaction in which one of the ions from a salt reacts with water, forming either an acidic or basic solution.
The fourteen elements (atomic number 90-103) after actinium are called?
Actinoids
Nucleotides
Pre-actinum elements
Atomic elements
Correct answer is A
The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.
The actinide series derives its name from the first element in the series, actinium.
Electron gain enthalpy
Ionization enthalpy
Enthalpy change
Enthalpic gas removal
Correct answer is B
- The enthalpy change associated with the removal of the first electron from an isolated gaseous atom.
- Ionization enthalpy is the minimum amount of energy required to detach from an isolated gaseous atom the most loosely bound electron and turn it into a gaseous cation.
