An 8.0 L sample of neon gas at 300. K exerts a pressure of 900. kPa. If the gas is compressed to 2.0 L and the temperature is ra
svetoff [14.1K]

Answer:

7200 kPa

Explanation:

Applying,

PV/T = P'V'/T'................ Equation 1

Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas

Make P' the subject of the equation

P' = PVT'/V'T.............. Equation 2

Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K

Substitute these values into equation 2

P' = (900×8×600)/(2×300)

P' = 7200 kPa

In the reaction between copper sulphate solution and sodium sulphide solution, 15.9 g copper sulphate completely reacts with 7.8
nikitadnepr [17]

Answer:

The mass of formed sodium sulphate solution is 14.2 g.

Explanation:

From the given,

Mass of copper sulphate = 15.9 g

Mass of sodium sulphide = 7.8 g

Total mass of reactant  =  Mass of copper sulphate + Mass of sodium sulphide

                                     = 15.9 + 7.8g = 23.7g

Mass of copper sulphide formed = 9.5 g

Mass of sodium sulphate = Total mass - Mass of copper sulphide

                                          = 23.7 g - 9.5 g = 14.2 g

Therefore, The mass of formed sodium sulphate solution is 14.2 g.

show by means of a balanced equation how many moles of N2 will be used in reaction to H2 to form 17 moles of NH3
77julia77 [94]
The balanced chemical reaction is:<span>

N2 + 3H2 = 2NH3

<span>We are given the amount of the product to be produced. This will be the starting point of our calculations.

17 mol NH3 ( 1 mol N2 / 2 mol NH3 ) = 8.5 mol N2

Therefore, the required N2 to produce the given amount of ammonia is 8.5 mol.</span></span>
