Answer:

2500 J

Explanation:

Let's solve the problem using the first law of thermodynamics, which states that

U_f - U_i = Q-W

where

Uf is the final internal energy

Ui is the initial internal energy

Q is the heat absorbed by the system

W is the work done by the system

In this problem, we have:

Ui = 2000 J is the initial internal energy

Q = 1000 J is the heat absorbed by the system

W = 500 J is the work done by the piston

If we substitute numbers into the equation, we find:

U_f =U_i + Q-W=2000 J+1000 J-500 J=2500 J

Answer:

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

Explanation:

$2CuO+C\rightarrow 2Cu+CO_2$

1 Ton = 907185 grams

Mass of copper oxide = 1.0 Ton = 907185 grams

Moles of copper oxide = $\frac{907185 g}{79.55 g/mol}=11,403.95 moles$

According to reaction, 2 moles of copper oxide reacts with 1 mole of carbon.

Then 11403.95 moles of copper oxide will react with:

$\frac{1}{2}\times 11403.95 mol=5,701.98 mol$ of carbon

Mass of 5,701.98 moles of carbon:

$5,701.98 mol\times 12 g/mol=68,423.75 g$

Mass of coke = x

Mass of carbon = 68,423.75 g

Percentage of carbon in coke = 95%

$95\%=\frac{68,423.75 g}{x}\times 100$

$x=720,250.09 g=0.794 Ton$

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.
