Answer:
co2 is a compound.
Explanation:
Oxygen(O) is an element having atomic number 8 and mass number 16.
Carbondioxide is a compound formed by burning of carbon and organic compound and it is a colorless and odorless gas.
O2 is the molecular form of Oxygen.
Cobalt(Co) is an element having atomic number 27 and mass number 59.
The potential energy the bucket started with transforms into kinetic energy as it moves.
Explanation:
Large hydrocarbon molecules can be cracked in an oil refinery through the process of cracking. Cracking of hydrocarbons involves the use of heat, pressure and catalyst to resolve heavy hydrocarbons into simpler and more useful products.
- Cracking of hydrocarbons is very essential in the oil refinery.
- Cracking helps to break giant hydrocarbon molecules into simple and more useful ones.
- Fractional distillation separates oil molecules into its different components based on their different boiling points.
- The fractions produced a times are usually long chained and are not in high demand.
- Catalytic cracking and thermal cracking helps to break the long chains of the heavy hydrocarbons fractions into simpler ones.

For such calculation, we apply Planck's equation:
E = nhc / λ; where n is the number of photons, h is the Planck's constant, c is the speed of light and λ is the wavelength of the light.
As is visible from the equation, energy and wavelength have an inverse relationship. Therefore, larger energy drops produce smaller wavelengths and smaller drops produce larger wavelengths.
-269.65 °C is the temperature in °C if 1.32 moles of a gas that occupies.35 L at a pressure of 1.06 atm.
Explanation:
Data given:
number of moles of the gas, n = 1.32
volume of the gas, V = 0.35 litres
pressure of the gas, P = 1.06 atm
temperature, T =?
R (gas constant) = 0.0821 L atm/mole K
Applying the equation for the ideal gas law:
PV = nRT
rearranging the equation:
T = 
putting the values in the equation:
T = 
T = 3.5 K
since the unit of temperature obtained is in degrees the temperature in Kelvin is -269.65 degrees. As 0 Kelvin = -273.15 celsius
formula is K -273.15
So,
3.5 - 273.15
= -269.65 celsius
