What is sodium + oxygen when doing ionic bonds

1 answer:

5 0

When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).

4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.

Under normal conditions, approximately 20% of the mixture is Na2O2.

6 Na + 2 O2 → 2 Na2O + Na2O2

If 5 L of butane is reacted what volume of carbon dioxide is produced ILL GIVE BRAINLIEST

Len [333]

Answer: First, here is the balanced reaction: 2C4H10 + 13O2 ===> 8CO2 + 10H2O.

This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.

Next, let's determine how many moles of butane are burned. This is obtained by

5.50 g / 58.1 g/mole = 0.0947 moles butane. As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947 = 0.1894 moles CO2.

Now we need to figure out the volume. This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions: 273 K and 1 atmosphere.

We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).

V = 0.1894 x 0.082 x 273.0 / 1 = 4.24 Liters.

Answer:

The deviations are :

The activation energy which changes with temperature
The arrhenius constant which depends on the temperature

Explanation:

There are deviations from the Arrhenius law during the glass transition in all classes of glass-forming matter.

The Arrhenius law predicts that the motion of the structural units (atoms, molecules, ions, etc.) should slow down at a slower rate through the glass transition than is experimentally observed.
In other words, the structural units slow down at a faster rate than is predicted by the Arrhenius law.
This observation is made reasonable assuming that the units must overcome an energy barrier by means of a thermal activation energy.
The thermal energy must be high enough to allow for translational motion of the units which leads to viscous flow of the material.

Both the Arrhenius activation energy and the rate constant k are experimentally determined, and represent macroscopic reaction-specific parameters that are not simply related to threshold energies and the success of individual collisions at the molecular level.
Consider a particular collision (an elementary reaction) between molecules A and B. The collision angle, the relative translational energy, the internal (particularly vibrational) energy will all determine the chance that the collision will produce a product molecule AB.
Macroscopic measurements of E(activation energy) and k(rate constant ) are the result of many individual collisions with differing collision parameters. They are averaged out to a macroscopic quantity.

If we increase pressure on the gas what happens to the temperature?

irinina [24]

Answer: Temperature will Increase

PV=nRT. Ideal Gas Law

We see by inspection of the ideal gas law, there is a liner relationship between Pressure and Temperature of an ideal gas. So if the pressure is increased on the gas, then the Temperature will increase also.

Any questions please feel free to ask. Thanks and have a great day!
