What is the ratio for O2 to CO2

O2• The rates of CO2 uptake and O2 evolution exhibit nearly identical responses to CO2 pressure within each species while the absolute rate of CO2 uptake appears to be slightly higher than the rate of O2 evolution at all CO2 pressures, giving a C02/02 exchange ratio of 1.04 to 1.14.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
