Avogadro's Law states that the volume of any gas is proportional to the number of mole molecules of the gas. Calling, n the number of moles of molecules of the gas, the proportionality equation is: V is proportional to n => V = K*n. The proportionality constant depends on the temperature and pressure. K = (RT / P) => V = (RT/P) * n, So, Avogadro's law states that <span>at constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of molecules of the gas.</span>

The unsaturated hydrocarbon butadiene (C4H6) dimerizes to 4-vinylcyclohexene (C8H12). When data collected in studies of the kine

UkoKoshka [18]

Answer:

The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :

$R=k[C_4H_6]^2$

Explanation:

$2C_4H_6\rightarrow C_8H_{12}$

The rate of the reaction ;

$R=k[C_4H_6]^x$

As given in the question , that graph of time verses $\frac{1}{[C_4H_6]}$ was linear but plots of $[C_4H_6]$ or $\ln[C_4H_6]$ was curved.

Generally:

Graph of time verses $[concentration]$ for zero order reaction is linear with negative slope.

Graph of time verses $\ln [concentration]$ for secon order reaction is linear with negative slope.

Graph of time verses $\frac{1}{[concentration]}$ for secon order reaction is linear with positive slope.

So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :

$R=k[C_4H_6]^2$

Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous butane into gaseous carbon d

Phantasy [73]

Answer:1.

1.Balanced equation

C4H10 + 9 02 ==> 5H20 +4CO2

2. Volume of CO2 =596L

Explanation:

1.Combustion of alkane is the reaction of alkanes with Oxygen. And the general equation for the combustion is;

CxHy +( x+y/4) O2 ==> y/2 02 + xCO2

Where x and y are number of carbon and hydrogen atoms respectively.

For butane (C4H10)

x=4 and y=10

Therefore

C4H10 + 9 02 ==> 5H20 +4CO2

2. Mass of butane = 0.360kg

Molar mass of C4H10 = ( 12×4 + 1×10)

= 48 +10=58g/mol= 0.058kg/mol

Mole = mass/molar mass

Mole = 0.360/0.058= 6.2moles

From the stoichiometric equation

1mole of C4H10 will gives 4moles of CO2

Therefore

6.2moles of C4H10 will gives 4 moles of 24.8 moles of CO2

Using the ideal gas equation

PV=nRT

P= 1.0atm

V=?

n= 24.8mol.

R=0.08206atmL/molK

T=20+273=293

V= 24.8 × 0.08206 × 293

V= 596L

Therefore the volume of CO2 produced is 596L

jarptica [38.1K]

Answer: Provided in the explanation section

Explanation:

Our questions says that:

It is usually assumed that an action potential begins immediately at the cathode. If this were true, both methods for calculating conduction velocity would provide the same answer. However, when a strong stimulus intensity is used, the action potential may begin some distance away from the cathode. Under these conditions, the difference method would be more accurate.Did you observe any important difference between the conduction velocity values?

Answer to this :

By using the difference method, you subtract out any "uncertainties" involved in the measurement of latencies. Say for example, saw we are uncertain as to where the AP's are actually originating within the vicinity of the stimulating electrodes, this "error" will be introduced into both latency measurements, and therefore subtracted out when performing a difference method calculation.

However, the difference method is only experimentally sound when one is dealing with the same population of nerve fibres over the recording electrodes used, which is not the case with the sciatic nerve, as it is a short nerve, and thin at one end.

The non-uniformity of the nerve, and the difficulty in making accurate measurements of very small distances and latencies are principal points to consider when making conduction velocity measurements. Naturally if the nerve studied were longer and more uniform, we would improve the accuracy of our calculations.

cheers i hope this helped !!!!
