The reaction below shows how silver chloride can be synthesized.
Vesna [10]
AgNO_{3} _{(aq)}  +  NaCl_{(aq)}  ----\ \textgreater \   NaNO_{3} _{(aq)}   +  AgCl _{(aq)}
mole ration of AgCl _{(aq)}  :  AgNO_{3} _{(aq)} =  1 : 1

∴ if moles of  AgNO_{3} _{(aq)} =  15.0 mol
then   "      "     AgCl _{(aq)}  =  15.0 mol

∴  the Option  2 is the answer.

3 The volume of a gas is 50.0 mL at 20.0 K. What will be the new
Damm [24]

Answer:

C. 4.00 K

Explanation:

We can solve this using Charles's Law of the ideal gas. The law describes that when the pressure is constant, the volume will be directly proportional to the temperature. Note that the temperature here should only use the Kelvin unit. Before compressed, the volume of the gas is 50ml(V1) and the temperature is 20K (T1). After compressed the volume becomes 10ml(V2). The calculation will be:

V1 / T1= V2 / T2

50ml / 20K = 10ml / T2

T2= 10ml/ 50ml * 20K

T2= 4K
