Answer:

Single replacement

Explanation:

A reaction in which one element replaces a similar element is called single replacement.  In this case, C is replacing A.

A gas expands at a constant pressure of 3 atm from a volume of 0.02 cubic meters to 0.10 cubic meters. In the process it experie
Nonamiya [84]

a) 2.4\cdot 10^4 J

For a gas transformation occuring at a constant pressure, the work done by the gas is given by

W=p(V_f -V_i)

where

p is the gas pressure

V_f is the final volume of the gas

V_i is the initial volume

For the gas in the problem,

p=3 atm = 3\cdot 1.013\cdot 10^5 Pa = 3.039\cdot 10^5 Pa is the pressure

V_i = 0.02 m^2 is the initial volume

V_f = 0.10 m^3 is the final volume

Substituting,

W=(3.039\cdot 10^5 Pa)(0.10 m^3-0.02m^2)=24312 J = 2.4\cdot 10^4 J

b) 3.24\cdot 10^5 J

The heat absorbed by the gas can be found by using the 1st law of thermodynamics:

\Delta U = Q-W

where

\Delta U is the change in internal energy of the gas

Q is the heat absorbed

W is the work done

Here we have

\Delta U = 3.0\cdot 10^5 J

W=2.4\cdot 10^4 J

So we can solve the equation to find Q:

Q=\Delta U + W = 3.0\cdot 10^5 J +2.4\cdot 10^4 J = 3.24\cdot 10^5 J

And this process is an isobaric process (=at constant pressure).

What is the kinetic energy of a 400kg house that is racing around a track at 17 meters per second?
nasty-shy [4]

Kinetic energy = (1/2) (mass) (speed squared)

Kinetic energy = (1/2) (400 kg) (17 m/s)²

Kinetic energy = (1/2) (400 kg) (289 m²/s²)

<em>Kinetic energy = 57,800 Joules</em>

<em></em>

(That's some amazing house.  I'd like to be there to see it.)
