<em>Answer:</em>

  • At 60 centigrade, the kinetic energy of the substance will be greatest.

<em>Explanation:</em>

As we know, the kinetic energy of substance is directly proportional to Temperature.

The total Kinetic energy can be calculated as follow

                                                K.E = 3/2 n.R.T

From the equations, it is cleared that Temperature is directly proportional to temperature.

Three kilograms of steam is contained in a horizontal, frictionless piston and the cylinder is heated at a constant pressure of
lakkis [162]

Answer:

Final temperature: 659.8ºC

Expansion work: 3*75=225 kJ

Internal energy change: 275 kJ

Explanation:

First, considering both initial and final states, write the energy balance:

U_{2}-U_{1}=Q-W

Q is the only variable known. To determine the work, it is possible to consider the reversible process; the work done on a expansion reversible process may be calculated as:

dw=Pdv

The pressure is constant, so:  w=P(v_{2}-v_{1} )=0.5*100*1.5=75\frac{kJ}{kg} (There is a multiplication by 100 due to the conversion of bar to kPa)

So, the internal energy change may be calculated from the energy balance (don't forget to multiply by the mass):

U_{2}-U_{1}=500-(3*75)=275kJ

On the other hand, due to the low pressure the ideal gas law may be appropriate. The ideal gas law is written for both states:

P_{1}V_{1}=nRT_{1}

P_{2}V_{2}=nRT_{2}\\V_{2}=2.5V_{1}\\P_{2}=P_{1}\\2.5P_{1}V_{1}=nRT_{2}  

Subtracting the first from the second:

1.5P_{1}V_{1}=nR(T_{2}-T_{1})

Isolating T_{2}:

T_{2}=T_{1}+\frac{1.5P_{1}V_{1}}{nR}

Assuming that it is water steam, n=0.1666 kmol

V_{1}=\frac{nRT_{1}}{P_{1}}=\frac{8.314*0.1666*373.15}{500} =1.034m^{3}

T_{2}=100+\frac{1.5*500*1.034}{0.1666*8.314}=659.76 ºC

Predict the product of this chemical equation. please explain how u did it. Do not balance after finding answer.
Oksanka [162]

Answer:

The products are CO₂ and H₂O.

The ballanced equation is this:

2C₄H₆ + 11O₂  →   8CO₂  +   6H₂O

Explanation:

In any chemical reaction, where you see that you have a compound reacting only with oxygen (O₂), you are in front of combustion.

Products in combustion are always water vapor and carbon dioxide.

Take a look to the methane combustion.

CH₄  +  2O₂  →  CO₂  +  2H₂O

1 mol of methane reacts with 2 moles of oxygen to form 1 mol of CO₂ and 2 moles of water.

This is the combustion for an alkene where 2 moles of the alkene reacts with 11 moles of oxygen to make water and CO₂ like this:

2C₄H₆ + 11O₂  →   8CO₂  +   6H₂O

Classify the following specific inhibitors or inhibitor characteristics according to one of three types of inhibition: reversibl
Paraphin [41]

Answer:

A inhibitor structure resembles substrate structure B inhibitor binds non covalently at site other than active site.C  inhibitors bind covalently and permanently at active site.

Explanation:

A Reversible competitive inhibitors structurally resembles the substrate and competes with the substrate to bind to the active site of the target enzyme.

B Reversible noncompetitive inhibitors binds no covalently at site of the target enzyme that is different from the active site.

C irreversible inhibitors interacts very tightly to the active site of an enzyme by covalent bond which cannot be overcome.
