What was the original pressure in a rigid container if the new pressure is 82.5atm and the temperature was raised from 44C to 67

zhenek [66]

Answer: 54 atm

Explanation:

I did 67/82.5 then got 0.8121212121. I them divided 44 by 0.81212121 and got 54.1791044776

the compressor exerts a pressure of 400 Pa to compress nitrogen gas from 3 L to 1 L. If no heat transfer occurs, how much will t

Triss [41]

Answer:

0.79014 J

Explanation:

According to the first law of thermodynamics:-

$\Delta U = q + w$

Where,

U is the internal energy

q is the heat

w is the work done

From the question,

q = 0 J

The expression for the calculation of work done is shown below as:

$w=P\times \Delta V$

Where, P is the pressure

$\Delta V$ is the change in volume

From the question,

$\Delta V$ = 3 - 1 L = 2 L

P = 400 Pa

The expression for the conversion of pressure in Pascal to pressure in atm is shown below:

P (Pa) = $\frac {1}{101325}$ P (atm)

Given the value of pressure = 43,836 Pa

So,

400 Pa = $\frac {400}{101325}$ atm

Pressure = 0.0039 atm

$w=0.0039\times 2\ atmL$

Also, 1 atmL = 101.3 J

So,

$w=0.0039\times 2\times 101.3\ J=0.79014\ J$ (work is done by the system)

So,

$\Delta U = 0\ J+0.79014\ J =0.79014\ J$

Is 2 C4H10 + 13 O2 → 8 CO2 + 10 H2O a double replacement?

natulia [17]

Answer:

The answer to your question is No, it is not.

Explanation:

Data

C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O

In a double replacement reaction, two reactants interchange cations an example of these reactions are neutralization reactions. In neutralization reactions, an acid and a base react to form a salt and water.

The reaction of this problem is not a double replacement reaction because the products are carbon dioxide and water, not a salt and water.

The reaction of this problem is a combustion reaction.
