Answer:
CH4<HClO2<HClO<H2O<HCl
Explanation:
In ranking the compounds on the basis of increasing positive charge of hydrogen, we must consider the relative oxidation numbers of the various elements in the compounds.
Methane contains a nonpolar covalent bond, HClO2 contains a chlorine atom in +3 oxidation state, HClO contains a chlorine atom in +1 oxidation state. The more the positive charge on the halogen atom the lesser the magnitude of positive charge on the hydrogen atom. Between water and HCl, chlorine is more electro negative hence HCl will contain a more positively charged hydrogen atom than water.
Answer:
Scientific Explanation of weather change and cause storms is described below in detail.
Explanation:
The weather is just the nature of the environment at any time, including items such as warmth, rainfall, air pressure, and cloud shelter. Daily variations in the weather are due to storms and winds. Seasonal variations are due to the Earth spinning nearby the sun. Warm beginnings often produce stormy weather as the heated air mass at the exterior rises above the cool air mass, creating clouds and storms.
Answer:
Because of statements (a), (c) and (d).
Explanation:
Let's evaluate each statement to know why they focus on higher alcohols instead of ethanol:
(a) It is easier to produce higher alcohols in microbes than it is to produce ethanol<u>.</u> This is true<u> since ethanol is the major biofuel in the world because it can be easily produced by fermentation technology developed a long time ago. Recently, higher alcohols are produced from microorganisms that are used as microbial cell factories.</u>
(b) Higher alcohols have a higher hygroscopicity than ethanol. This is false since ethanol is more hygroscopic than higher alcohols.
(c) Higher alcohols have a lower vapor pressure than ethanol. This is true, ethanol has a higher vapor pressure than higher alcohols. The vapor pressure is important since it can affect the proper cold starting of the engine.
(d) Higher alcohols have a higher energy density than ethanol. This is true since the production of higher alcohols as biofuels is more desirable than the ethanol because higher alcohols have a high energy density and other more advantages than the use of ethanol.
Therefore the answer of why did they focus on higher alcohols to add to or substitute gasoline instead of ethanol is because of the statements (a), (c) and (d).
I hope it helps you!
The temperature will be lower and the water could either become really cold or freeze. I can't exactly tell you because you're not saying if it's Celsius or Fahrenheit. <span />
