Chemistry: Fun Trivia Style Trivia Quiz

Answer: Hydrogen

Elements on the s block are hydrogen, the alkali metals (lithium, sodium, potassium, rubidium, cesium, and francium), and the alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium). They can have up to two electrons in their outermost shell.

Answer: Ethyl alcohol

A non-electrolyte does not dissociate in water whereas electrolytes do. Common non-electrolytes are alcohol, sugar, water, and other carbon compounds, while electrolytes include acids, bases, and soluble salts.

Answer: 6 protons and 7 neutrons

Isotopes are nuclei that have a different number of neutrons while always keeping the same number of protons. That yields a different atomic mass. The atomic number of carbon is 6, so that means it has 6 protons. A carbon-13 isotope has an atomic mass of 13. That gives it 7 neutrons because the atomic mass is the sum of protons and neutrons.

Answer: n=4, l=3, ml=-1, ms=1/2

The quantum number n represents the size of the orbital. It can be any number 1 and above. The quantum number l stands for the orbital's shape. It can be 0 up to the value before n. The quantum number ml, the direction of the orbital, can be -l to l. And finally, the quantum number ms refers to the orbital's upward and downward spin represented by -1/2 or 1/2.

Answer: 7.18m

The molality of a solution can be found by dividing the number of moles of solute by the mass of the solvent in kilograms when converted from grams. The answer is typically rounded to three significant figures.

Answer: Zinc and Copper

Brass is an alloy (metallic solution) of zinc and copper. It is used to make rings and knuckles. It is also used to make musical instruments such as trumpets, tubas, and other members of the horn family.

Answer: 0

Oxygen has an oxidation number of -2, and hydrogen has an oxidation number of 1. The chemical formula becomes an equation that equals to 0, and the number of atoms are multiplied by the corresponding oxidation numbers. Then the unknown oxidation number of an element is found by solving the equation.

Here, we have the formula of sucrose C12H22O11. The oxidation numbers of hydrogen and oxygen yield the equation 12C*+1*22-2*11=0 which becomes 12C+22-22=0. The 22s cancel out, leaving 12C=0. When you divide by 12, you get the oxidation number of carbon, which is (obviously) 0.

Answer: basic

A pH between 1-6.9 is acidic, a pH of 7 is neutral, and a pH between 7.01-14 is basic. A pH of 13.6 is between 7.01 and 14, so the solution is basic.

Answer: dipole-induced dipole

Water, a polar molecule, interacting with carbon dioxide, a nonpolar molecule, is an example of a dipole-induced dipole occurring. This typically happens during photosynthesis as shown in the equation 6CO2+6H2O->C6H12O6+6O2.

Answer: vaporization

Vaporization is where a liquid changes to a gas, usually upon heating. Sublimation refers to when a solid changes to a gas (e.g. dry ice becoming carbon dioxide). Deposition occurs when a gas becomes a solid and condensation happens when a gas becomes a liquid (both typically occurring within the atmosphere).
