Antarctic soils exist, in general, they comprise a surface pavement (i.e., a layer of gravel, stones or boulders formed largely by weathering and the removal of fine materials mainly by wind action) and a seasonally thawed active layer over permafrost.
Answer:
the answer is 11.111 and when you round it to the nearest one it’s 11, but to the nearest tenth it’s 10
Explanation:
There are three possible Isomers for Molecular Formula C₃H₄. Isomers are;
1) Propyne 2) Propa-1,2-diene 3) CyclopropeneStructures of all three isomers are given below.
There are no geometrical isomers for given molecular formula because geometrical isomers are formed in compounds containing double bond with at least two bulky groups at both sp² hybridized carbons. In given isomers, propyne does not contain any double bond, Propa-1,2-diene is symmetrical in nature while cyclopropene is a 3-membered ring. And for cycloalkenes there must be other groups attached to ring other than Hydrogen atom, hence cyclopropene does not contain any other group, so it can not show geometrical isomerism.
Answer:
calcium hydroxide.............
Answer: The correct answer is absorbed.
Explanation:
Bond formation is a type of exothermic process. In these reactions when two atoms come close to each other, energy is released in this process.
On the other hand, in the breaking of bond, energy is required because the atoms are to be separated from each other. This is a type of endothermic process. So, the energy must be absorbed.
Hence, the correct answer is absorbed.
