(A)hydrochloric acid + silver nitrate
HCl(aq) + AgNO3(aq) -----> AgCl(s) +HNO3(aq)

(B)hydrochloric acid + sodium hydroxide
HCl(aq) + NaOH(aq) -----> NaCl(aq) + H2O(l)

(C)calcium chloride + silver nitrate
CaCl2(aq) + AgNO3(aq) ----> AgCl(s) +Ca(NO3)2(aq)

(D)sodium chloride + silver nitrate
NaCl(aq) + AgNO3(aq) ----> AgCl(s) +NaNO32(aq)

AgCl is a white precipitate.
In (B) no precipitate was formed, so answer is B.

Density = Mass over Volume

D = m/V

<h3>Explanation:</h3>

Step 1: Define

D = 25 g/cm³

m = 100 g

Step 2: Solve for V

Substitute variables [D]: $\displaystyle 25 \ g/cm^3 = \frac{100 \ g}{V}$
Multiply V on both sides: $\displaystyle V(25 g/cm^3) = 100 \ g$
Isolate V: $\displaystyle V = 4 \ cm^3$

Reaction of HBr with 3-methylcyclohexene yields a mixture of four products cis-and trans-1-bromo-3-methylcyclohexane and cis-and

Umnica [9.8K]

Answer:

See explanation

Explanation:

The mechanism of this reaction including intermediates are shown in the image attached to this answer.

The reaction of HBr with 3-bromocyclohexene yields trans-1,2-dibromocyclohexane as the sole product because; the proton first attacks the 3-bromocyclohexene and a brominium ion is formed. This brominium ion is a cyclic intermediate as shown in the image attached.

Attack of a bromine ion afterwards must lead to the formation of trans-1,2-dibromocyclohexane as shown.
