(E) I, II, and III are correct. ...

(A) Only I is correct. ...

(D) HCl is actually a stronger Brønsted-Lowry acid than H 2 O, which is why the reaction occurs as shown. ...

(D) The name carbon-13 supplies enough information to determine the number of all three subatomic particles. The name carbon in ...

(B) III is a salt from a strong base and a weak acid, which hydrolyzes to form a basic solution with water. ...

(B) Since NaCl dissociates into two ions, it can change the boiling point of water more than the ethyl alcohol does, which does ...

(B) The VSEPR model shows BF 3 is trigonal planar and so is related to the triangle shape on one plane. ...

(C) The delivery tube is below the fluid level in the flask and will cause liquid to be forced up the thistle tube when gas is ...

(A) At first the fluid will be expelled up the thistle tube by the gas generated and exerting pressure in the reaction flask. W ...

(A) The most active nonmetal has a high attraction for another electron—thus high electronegativity. ...

(B) Fe loses electrons to form the Fe^2 ion. ...

(D) The Kw of water = [H+][OH−] = 10−14. If [OH−] = 10−5 mol/L, then ...

(C) The oxidation state of oxygen in hydrogen peroxide (H 2 O 2 ) is –1. In the products the oxidation state is both –2 (in H ...

(C) The correctly balanced equation is C 2 H 4 (g) + 3O 2 (g) → 2CO 2 (g) + 2H 2 O(l) ...
