Given the properties of atmospheric carbon dioxide, how might the presence of co2 in the air affect the accurate measurement of acid concentration using an indicator in a natural sample?

Answer and Explanation:

Carbon dioxide (CO₂) dissolves in water and gives carbonic acid (H₂CO₃) which then dissociates first in HCO₃⁻ and then in CO₃⁻. So, its ionization increases the concentration of H⁺ and the solution becomes more acidic. If you measure the pH of a sample by using a colorimetric indicator and then you exhale your CO₂ in the sample, you will see that the indicator changes its color to the correspondent to a acid solution.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
