Hydrogen sulfide gas is reacted with dioxygen gas to produce gaseous sulfur dioxide and water. True or false?.

wel

Hydrogen sulfide gas is reacted with dioxygen gas to produce gaseous sulfur dioxide and water. It is false.

When hydrogen sulfide gas reacts with dioxygen gas, it produces water and solid Sulphur and not gaseous sulfur. The chemical equation of the given substances is :

2H2S + O2 → 2S + 2H20

It is a redox reaction as both Oxidation and reduction happens in it. Oxidation of hydrogen sulphur to sulphur happens and reductions of oxygen to water takes place.

Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 58 mm Hg. Assume hemoglobin is 50% sat

svetlana [45]

Answer:

0.8988

Explanation:

To calculate the fractional saturation of hemoglobin , the formula used is

YO_2= $\frac{(pO_2)^n}{(p50)^n+(pO_2)^n}$

now putting the values

YO_2= $\frac{58^3}{28^3+58^3}$

= $\frac{195112}{21952+195112}$

=0.8988

Therefore, fractional saturation of hemoglobin= 0.8988

where

YO_2= fractional saturation of hemoglobin

pO_2= partial pressure of oxygen

p50= is the pO_2 at which hemoglobin is 50% saturated

In a single carbon bond, two carbon atoms share pair of electrons.

torisob [31]

Answer:

C-C

A carbon has 4 valence electrons meaning it can share 4 electrons and is in short of 4 electrons to fill it outer energy shell making it 8. Which results to 2 double covalent bonds ,meaning there was a sharing of 2(4) = 8 electrons . Hope this helps . Your statement above is true .
