Is sulfuric acid a binary compound? It is element stem + “ic acid” (or “ous acid”). This gives names like sulfuric acid and nitric acid. The “hydrogen name” is formed as if the substance were an ionic compound. So the name would be hydrogen sulfate, but that name is hardly ever used. Is hydrocyanic acid […]
Who described the shape of the earth?
Who described the shape of the earth? Isaac Newton What is an oval sphere called? prolate. A spheroid, or ellipsoid of revolution, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. What is a globe? […]
What occurs in a point mutation?
What occurs in a point mutation? Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the […]
Which one is continuous for all values of x?
Which one is continuous for all values of x? Any polynomial is continuous for all values of x. Is function continuous at a hole? The function is not continuous at this point. This kind of discontinuity is called a removable discontinuity. Removable discontinuities are those where there is a hole in the graph as there […]

It is harmful to our health, and it impacts the environment – reducing visibility and blocking sunlight, causing acid rain, and harming forests, wildlife, and agriculture. Greenhouse gas […]
What happens to the entropy of water when it is boiling?
What happens to the entropy of water when it is boiling? When the water boils, the entropy change is quite large (ΔSvaporization = 109 J/mol K), as the molecules go from being relatively constrained in the liquid to gas molecules that can fly around. At temperatures lower than the boiling point, the enthalpy term predominates […]
