2AgNO3(aq) + Na2S(aq) → Ag2S(s) + 2NaNO3(aq)

What Is The Precipitate In The Following Reaction?2AgNO3(aq) + Na2S(aq) Ag2S(s) + 2NaNO3(aq)

Answers

Answer 1

Answer:

2Ag(+1)(aq) + S(-2)(aq) --> Ag2(+1)S(-2)(aq)

Explanation:

The final equation is

2Ag(+1)(aq) + S(-2)(aq) --> Ag2(+1)S(-2)(aq)

2Ag(+1)NO3(-1)(aq) + Na2(+1)S(-2)(aq) --> Ag2(+1)S(-2)(s) + 2Na(+1)NO3(-1)(aq)

AgNO3, Na2S, and NaNO3 are all strong electrolytes, so we immediately separate those, making the new equation:

2Ag(+1)(aq) + 2NO3(-1)(aq) + 2Na(+1)(aq) + S(-2)(aq) --> Ag2(+1)S(-2)(s) + 2Na(+1)(aq) + 2NO3(-1)(aq)

After that, you cancel out all the ions that appear more than once, which in this case would leave us with a final equation of...

2Ag(+1)(aq) + S(-2)(aq) --> Ag2(+1)S(-2)(aq)

A 35 L tank of oxygen is at 42°C with an internal pressure of 5000.mmHg. If the temperature changes to 88°C, what would the new pressure be ? the volume is held constant

Answers

Answer:

5730 mmHg.

Explanation:

The following data were obtained from the question:

Initial temperature (T1) = 42 °C.

Initial pressure (P1) = 5000 mmHg.

Final temperature (T2) = 88 °C.

Final pressure (P2) =.?

Next we shall convert celsius temperature,T(°C) to Kelvin temperature, T(K).

This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 42 °C.

Initial temperature (T1) = 42 °C + 273 = 315 K

Final temperature (T2) = 88 °C.

Final temperature (T2) = 88 °C + 273 = 361 K

Finally, we shall determine the new pressure.

Since the volume of the container is constant, the new pressure can be obtained as follow:

Initial temperature (T1) = 315 K.

Initial pressure (P1) = 5000 mmHg.

Final temperature (T2) = 361 K.

Final pressure (P2) =.?

P1/T1 = P2/T2

5000/315 = P2/361

Cross multiply

315 x P2 = 5000 x 361

Divide both side by 315

P2 = (5000 x 361) / 315

P2 = 5730.1 ≈ 5730 mmHg

Therefore, the new pressure is 5730 mmHg.

A sample of O2 gas is collected over water at 25oC at a barometric pressure of 751 torr. The vapor pressure of water at 25oC is 23.8 torr. What is the partial pressure of the O2 gas in the sample

Answers

Answer:

727.7 torr

Explanation:

Since the gas was collected over water, it is likely to be saturated with water vapour and the total pressure is given as;

Ptotal = Pgas + Pwater

From the question;

Ptotal = 751 torr

Pgas = ?

Pwater = 23.8 torr

Making Pgas subject of equation, we have;

Pgas = Ptotal - Pwater

Pgas = 751 torr - 23.8 torr

Pgas = 727.7 torr

what happens when ca no3 2 is heating it gives CaO ,NO2 and 02

Answers

Answer:

balanced equation:

2Ca(NO3)2 (aq)-----> 2CaO (s) + 4NO2 (g) + O2 (g)

So heating 2 moles of Ca(NO3)2 gives 2 moles of CaO, 4 moles of NO2 and 1 mole of O2. This is a heat decomposition reaction. It gives a white precipitate (CaO), and brown pungent gas (NO2).

Answer:

The balanced equation of the reaction is below.

Explanation:

2Ca(NO3)2 -----> 2CaO + 4NO2 + O2.

calculate the mass of sodium sulphate required to prepare its 20%of solution in 100 g ofwater​

Answers

Answer:

25 g

Explanation:

Mass percent implies the mass of solute dissolved in a solution

Mass percent = mass of solute/mass of solute + mass of solvent × 100/1

Since mass percent concentration= 20%

Mass of solvent = 100g

Let mass of solute = x

Hence;

20 = x/x +100 ×100/1

20/100= x/x + 100

0.2 = x/x + 100

0.2(x + 100) = x

0.2x + 20 = x

20 = x - 0.2x

20 = 0.8x

x= 20/0.8

x= 25 g
