The empirical formula CH₂ has a mass [(12 × 1) + (1 × 2)] = 14 g/mol
If the empirical formula is 14 g/mol,
and the molecular formula is ~140 g/mol
Then the multiple is = 140 g/mol ÷ 14 g/mol
= 10
Therefor the molecular formula is 10(CH₂) = <span>C</span>₁₀<span>H</span>₂₀<span> </span>
The hydrogen bond is a comparatively weak interaction between a proton hop and an electronegative atom present in a molecule. The hydrogen bond plays a very important role for the determination of state of a compound like gaseous, liquid or solid. The strength of the hydrogen bond depends on the close distance between the participants i.e. the electronegative atom and proton hop. There remains strong hydrogen bond between the two water molecules which is expressed as O....H. The distance of the hydrogen bond is 1.8A° formed between each proton hops of two neighboring water molecules. The hydrogen bond interaction is shown in the figure.
1. Answer is d. all of the above.
Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.
2. Answer is c. ozone.
Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.
