(C) An atom with atomic number 9 would have a 2,7 electron configuration, which matches the outer energy level of iodine. ...

(B) There are 2 Na, 1 C, and 3 O, which add to 6 atoms. ...

(A) pH from 0 to 6 is acid, 7 neutral, 8 to 14 basic. Most acid is 1. ...

(E) Molarity is defined as moles of solute/liter of solution. ...

(A) Gas densities can be expressed in grams/liter. ...

(C) Molar mass is not affected by pressure and temperature. ...

(A) If the density of a gas is known, the mass of 1 L can be multiplied by 22.4 to find the molecular mass because 1 mol occupi ...

(A) Buffers resist changes in pH. ...

(B) Color change is the function of indicators. ...

(C) On the pH scale, from 0 to 6 is acid and 7 is neutral. ...

(D) On the pH scale, from 8 to 14 is basic. ...

(E) The ozone (O 3 ) in the stratosphere absorbs ultraviolet rays from the sun. ...

(C) When hydrocarbons containing C and H do not have enough oxygen to combust with O 2 (g) completely, the product will be CO, ...

(A) 2KClO 3 → 2KCl + 3O 2 (g) is the reaction that occurs. ...

(D) CO 2 is slightly soluble in water, forming carbonic acid, H 2 CO 3 , which is a weak acid. ...

(B) SO 2 has the highest molar mass. ...

(T, F) The assertion is true, but the degree of motion of gas molecules is directly related to the temperature. ...

(T, T, CE) Assertion and reason are true; an electron can be treated as either an electromagnetic wave or a bundle of negative ...

(T, T, CE) A homologous series increases each member by a constant number of carbons and hydrogens. Examples are the alkane, al ...

(T, F) The nuclear charge of an active metallic ion is greater than that of the electron cloud. The reason is false. ...
