1.0 mole of KCl(aq) is added to which solution to produce a precipitate?

Chemistry
1 answer:
taurus [48]3 years ago
7 0

Answer:

Ag+

Explanation:

If you imagine as if the problem were double replacement, you would pair the Cl with one of the following ions provided in the choices. As seen on Table F, Ag+ paired with Cl- produces an insoluble compound, hence the precipitate. All the other ions shown in the multiple choice section, when paired with Cl- will produce a soluble compound, as a result NOT a precipitate.

How much (mL) of a 2.0 M sodium hydroxide solution would it take to neutralize 50 mL of a 6.0 M solution of hydrochloric acid?
Tom [10]

Answer:

150ml

Explanation:

For this question,

NaOH completely dissociates. It is a strong base

HCl also completely dissociates. It is a strong acid

So we have this equation

m1v1 = m2v2 ----> equation 1

M2 = 2m

V1= ??

M2 = 6m

V2 = 50m

When we input these into equation 1, we have:

2m x v1 = 6m x 50ml

V1 = 6m x 50ml/2

V1 = 300/2

V1 = 150ml

Therefore NaOH that is required to neutralize the solution of hydrochloric acid is 150ml.

Thank you

How many moles of gas are present when you collect 35.83 mL of the gas over water at 25.3°C and 0.97 atm?
Oksana_A [137]
Use Ideal Gas equation since values are given in Pressure (P), Volume (V), Temperature (T). 
                                 P V = n R T ; n= PV / RT
You can't use 1 mole= 22.4 L equation. Temperature and pressure values are not standard. ( 1 atm, 0 

To choose the value of R ( gas constant), check out the units of other values in the equation. They are in atm,liter, kelvin, and mole.  So, its value is 0.082 L atm/ K mol.

P= 0.97 atm
V= 35.83 * 10 ⁻³ L (conversion from ml to,  just multiplied by 10 ⁻³ )
R= 0.082 L atm/ K mol
T= (25.3 + 273) K ( recall Kelvin = Celcius + 273; K= °C + 273<span>)
</span>
Substitute values into equation of  n= PV / RT

n= 
(0.97 atm) (35.83 * 10 ⁻³ L) /  (0.082 L atm/ K mol) (298.3 K)= 0.014 mole

The answer is 0.014 mole
