[Ans] What is the chemical symbol for table salt?

Step 1 : Introduction to the question "What is the chemical symbol for table salt?"

Sodium chloride also known as table salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. Salt is necessary for life. Na+ ions are one of the main ions in the human body and are necessary to regulate the fluid balance in the body. Cl- ions are necessary for proper nerve function and respiration. Both of these ions are supplied by salt. The taste of salt is one of the fundamental tastes; salt is probably the most ancient flavoring known, and one of the few rocks we eat.

[Ans] What chemical element gives the blood of a lobster a bluish tint?

Step 1 : Introduction to the question "What chemical element gives the blood of a lobster a bluish tint?"

While humans and many other species have red blood, due to the iron in their hemoglobin, other animals have different colored blood. The bluish tint of a lobster's blood is due to the presence of copper found in the blue haemocyanin molecule in their blood. Hemoglobin, an iron-containing protein found in the blood of other animals—including humans—serves the same oxygen-transporting function but turns blood red. Some animals, such as the sea cucumbers, even have yellow blood. What could make blood yellow? The yellow coloration is due to a high concentration of the yellow vanadium-based pigment, vanabin.

[Answer] What is the only continent with a chemical element named for it?

Step 1 : Introduction to the question "What is the only continent with a chemical element named for it?"

...Europium is a chemical element with the symbol Eu. Europium is a ductile metal with a hardness similar to that of lead. Europium was isolated in 1901 and is named after the continent of Europe. Europium has no significant biological role and is relatively non-toxic compared to other heavy metals. Europium is one of the rarest of rare earth elements on Earth. French chemist, Eugene-Anatole Demarcay, is typically credited with the discovery of the element as he ultimately produced a relatively pure form of the rare earth metal in 1901.

[Ans] Which of these chemical elements is represented on the atomic table by a single letter?

Step 1 : Introduction to the question "Which of these chemical elements is represented on the atomic table by a single letter?"

Every element in the Periodic Table has been given a unique 1, 2 or 3 letter symbol. The first letter of an element symbol is always a capital letter. Many of the element symbols are quickly remembered with just one letter. These elements are: B for Boron, C for Carbon, F for Fluorine, H for Hydrogen, I for Iodine, K for Potassium, N for Nitrogen, O for Oxygen, P for Phosphorus, S for Sulfur, U for Uranium, V for Vanadium, W for Tungsten, and Y for Yttrium. Any subsequent letters, which make up the element symbols, are expressed in lower case, for example the chemical symbol for Gold is Au, Silver is Ag, and Sodium is Na.

[Ans] Based on their chemical symbols, which of these elements comes first alphabetically?

Step 1 : Introduction to the question "Based on their chemical symbols, which of these elements comes first alphabetically?"

Many symbols for chemical elements stem from classical Latin and Greek vocabulary. For some elements, this is because the material was known in ancient times, while for others, the name is a more recent invention. For example, the Latin name for gold is aurum. Thus, the chemical symbol for gold is Au. The symbol for lead is Pb (plumbum in Latin); Hg is the symbol for mercury (hydrargyrum in Greek). Some symbols come from other sources, like W for tungsten (Wolfram in German) which was not known in Roman times.

[Ans] Which former presidential candidate had campaign buttons with the chemical symbols Au and H2O?

Step 1 : Introduction to the question "Which former presidential candidate had campaign buttons with the chemical symbols Au and H2O?"

Barry Goldwater was an American politician best known as a senator from Arizona and the Republican candidate for president in 1964. Barry Goldwater's presidential campaign looked to the Periodic Table of elements for the now iconic campaign graphic (AU = gold and H2O = water). The campaign against Goldwater produced the "Daisy ad," one of the most famous political advertisements in American history, which presented nuclear war as a clear consequence of voting Republican in 1964. Goldwater lost the 1964 campaign for the presidency to Lyndon B. Johnson in unprecedented landslide.

[Answer] There are many chemical reactions that occur in the body. What broad term is used to include them all?

Step 1 : Introduction to the question "There are many chemical reactions that occur in the body. What broad term is used to include them all?"

...Catabolism means the breaking down of complex molecules into simpler ones, which often results in a release of energy. It is a phase of metabolism. Anabolism is the phase of metabolism in which simple substances are combined to form the complex materials of living tissue. Matabolism, with two As, does not exist.

[Ans] Which chemical element has the symbol K?

Step 1 : Introduction to the question "Which chemical element has the symbol K?"

Chemical symbols make up the Periodic Table of known elements. Each chemical symbol represents an abbreviation for the chemical element's name. Most come from the Latin name for the chemical. In the case of potassium, the letter "K" represents it on the Periodic Table. Sir Humphrey Davy discovered potassium in 1807. The name for the element comes from the Latin word "kalium." Potassium is from the mineral carnallite and is often used in making glass and soap. Source: ChemicalElements.com
