I believe its convention. Not a hundred percent sure though
The type of system that is associated with weather that is cold but sunny with almost no clouds in the sky is B. high pressure system.
Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. For a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature.
Answer:Ethanol can be made by a process called fermentation. During fermentation, sugar (glucose) from plant material is converted into ethanol and carbon dioxide. ... 90 per cent of the world's ethanol is made using fermentation.
Explanation:
Ethyl butyrate is also more commonly known as the ethyl butanoate with chemical formula of C₆H₁₂O₂. The equation of the butanoic acid (C₄H₈O₂) and ethanol (C₂H₆O) to form this substance can be written off as,
C₄H₈O₂ + C₂H₆O --> C₆H₁₂O₂ + H₂O
Note that the given equation is already balanced. Using dimensional analysis and conversion factors,
(8.5 g C₄H₈O₂)(1 mol/88.11 g)(1 mol C₆H₁₂O₂/1 mol C₄H₈O₂)(116.16 g / mol)
= 112.06 grams of ethyl butyrate
ANSWER: 112. 06 grams
