C cause if u think about it if u go to space and u through something it will keep going in that speed and never stop going in that direction!
Answer:
it's SN1 reaction,
it's takin double step to complete,first formation of carbocation and then attack of reagents,so it's SN1!
The general process for coal mining and refining is option C.
Coal mining is carried out by two main processes based on the depth, quality, thickness, and structure of coal seam. Based on the depth, coal seam of less than 180ft to the surface is surface mined while coal seems between 180ft.-300ft. are deep mined. The coal mined is transported to a nearby processing plant using a conveyor, train, ship, etc. where it is washed to remove other component like dirt, sulphur, rocks, etc. and afterwards dried.
Answer:
The required volume is 1.12 L.
Explanation:
Given,
Mass of O2 gas= 1.60 grams
We know,
Number of moles = Mass/Molecular mass
= 1.60/32 [Molecular mass of O2 gas is 32 gram]
= 0.05
Again,
We know that at STP,
Number of moles = Volume in L / 22.4 L
or, Volume = Number of moles X 22.4
or, Volume = 0.05 X 22.4
or, Volume = 1.12
∴The required volume is 1.12 L.
(35/18.02)(6.02kJ)=11.6926 kiloJoules
