Question

What is proportion of element in carbon dioxide

Answer 1

Answer:

In every sample of carbon dioxide, there is 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of 2.66 to 1.

Therefore, the proportion of element in carbon dioxide is 2.66 : 1

Answer 2

Answer - carbon dioxide is colourless. At low concentrations the gas is odorless; however, at sufficiently-high concentrations, is has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98kg/m3, about1.67that of the air
