Answer : The technology that can make coal a cleaner fuel is to use lower quality of coal with high sulfur content.
Explanation : Using lower quality of coal with high amount of sulfur in it can make coal a cleaner fuel because of high amount of sulfur it will have better combustion.
You can identify a compound to be an alcohol when it has a hydrocarbon chain and a hydroxyl functional group or -OH group. Also, from the name, you can tell that it is an alcohol is the suffix -ol is present. Examples are ethanol and methanol. Alcohol is any organic substance that contains an hydroxyl group bonded to a carbon atom that is saturated. Alcohols can be classified as primary, secondary or tertiary depending on where the hydroxyl functional group is attached in the hydrocarbon chain. It is a primary alcohol when OH is attached to the first carbon atom. Secondary alcohol, and tertiary alcohols has a general formula CHROH and CR2OH, respectively where R represents a hydrocarbon chain.<span />
Answer: 4.48L of CH4 at STP is equal to 1.2×10^23 molecules
Explanation:
The labeled diagram is given in the image attached.
As it can be seen from the image that freezing is when energy is removed from the system at 0 ⁰ while melting is when energy is added at 0⁰.
Also when energy is added at 100⁰C, it causes boiling while when it is removed at 100⁰C, it causes condensation.
Melting point of water is 0⁰C while boiling point is 100⁰C
Answer:Mass of Potassium chloride =1.762g
Explanation:
Mass of empty beaker = 23.100 g
Mass of beaker with Potassium chloride = 24.862g
Mass of Potassium chloride = Final weight - initial weight = Mass of beaker with Potassium chloride - Mass of empty beaker = 24.862-23.100 = 1.762g
