The <span>source of fuel that is most widely used today is Natural gas. The answer is letter C. The rest of the choices do not answer the question above,</span>
It is a mixture Beer is a homogeneous mixture (liquid solution) of H2O, C2H5OH, and a few other substances. (There is no beer molecule. The molecule that gives beer its inebriating property is ethanol.)
Answer:
0.2320V
Explanation:
Voltage can be defined as the amount of potential energy available (work to be done) per unit charge, to move charges through a conductor.
Voltage can be generated by means other than rubbing certain types of materials against each other.
Please look at attached file for solution to the problem.
Answer:
The correct answer is that both molecular motion, pressure and temperature increase as volume reduces.
Explanation:
A reduction in volume changes the molecular motion, temperature and pressure of the system. When the volume of the container decreases, this causes the pressure to increase, the temperature to increase and the molecular motion to increase. This is because a liquid and a solid are incompressible, so by reducing the volume of a gas, the molecules increase their movement as the temperature of the system increases, which is due to the increased pressure applied to reduce the volume of the system.
Have a nice day!
Answer:Overall equation:
a)CO(g) + NO2(g) → CO2(g) + NO(g)
b)Each step is bimolecular
c)Rate=k[NO2]^2
d)NO3 is an intermediate
Explanation:
To obtain the overall rate equation we cancel out reactants and products that are the same on both sides of the both steps. This leaves us with CO(g) + NO2(g) → CO2(g) + NO(g) as the overall stoichiometric reaction equation. Each step involves the reaction of two molecules hence each step in the mechanism is bimolecular. The slow step involves the reaction of NO2 hence the rate of reaction depends on the first step of the reaction hence the rate equation shown in the answer. Intermediates only take part in elementary steps but do not appear as products or reactants. They are produced and consumed transiently. NO3 is an intermediate in this reaction.
