The difference is the no. of charges  present in Carbon, meaning Carbon has different charges therefore Roman numerals are used to clarify the exact number.This makes balancing equations easier.

Also their names are different.
CO4 - Carbon tetroxide
CO2 - Carbon dioxide

Petroleum and coal can be mined from the continental shelf. t/f
bazaltina [42]
<span>True

Petroleum and coal can be mined from the continental shelf. Hot magma from inside the Earth seeps out from the crevices in the mid-ocean ridge. There is speculation regarding whether this is a cost-effective technique. Fossil fuels and mineral deposits can be located all throughout the continental shelf and also in some of the deepest depths of the ocean.</span>

If a climate scientist says, "The CO2 concentration in 2018 was 407.4 ppm." What<br> do they mean? *
Alinara [238K]

Answer:

Ppm <u>means the concentration of vapors or gases</u> expressed in parts per million of polluted air.

Explanation:

In Chemistry and Physics, part per million or PPM is a measure that expresses the number of units of a certain existing substance for every million units of the mixture. (Concentration)

In climate the equation is used so:

  • ppm = parts of polluted air / million parts of air .
  • ppm = Liters of polluted air / 10∧6 Liters  of air.

This is used to find the concentration of gases expressed as parts of gas per million parts of the

 polluted air.

In this case, it would be<u> 407.4L of CO2 per 10∧6L of air.</u>

The gas in an aerosol can is at a pressure of 3.16 atm at 32.2°C. What would the gas pressure in the can be at 22.9°C?
olasank [31]

Answer:

The pressure of the gas would be 3.06 atm

Explanation:

Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:

P1 / T1 = P2 / T2

<em>Where P1 is the initial pressure = 3.16atm</em>

<em>T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K</em>

<em>P2 is our incognite</em>

<em>And T2 is = 273.15 + 22.9°C = 296.05K</em>

<em />

Replacing:

3.16atm / 305.35K = P2 / 296.05K

3.06 atm = P2

<h3>The pressure of the gas would be 3.06 atm</h3>
