Answer: Small groups of atoms that are attached to larger molecules, giving the specific chemical properties, are called functional groups.
explanation: Functional groups are groups of atoms in a molecule that possess the same chemical feature every time it appears in several compounds. There are various types of functional groups and they have the tendency to react in definite ways. Examples include; the ether functional group (consists of an oxygen atom that forms single bonds with two carbon atoms),the alcohol functional group (consists of an oxygen atom that is bonded to one hydrogen atom and one carbon atom), and the amine functional group (consists of a nitrogen atom bonded to some combination of carbons and hydrogens).
It’s the measure of spaces between objects. It affects groundwater infiltration by having more water fill the spaces between it. For example, is you have bigger rocks the spaces between it are bigger therefore the groundwater infiltration rate is faster. If the rocks are smaller, they are tightly packed and it’s not easy for groundwater infiltration.
Answer:
wave length=speed/frequency

Answer:
<h2>Acetylene to ethene</h2>
First, acetylene is converted into ethene ( CH2 = CH2 ) using hydrogen gas and Lindlar catalyst. Ethene is an an alkene compound.
<h2>Lindlar catalyst</h2>
Alkynes are converted to alkenes by in the presence of hydrogen gas and lindlar catalyst.
lindlar reagent contains CaCO3, Pd and various forms of sulfur and lead
<h2>Ethene to ethanol</h2>
Then ethanol is prepared from the reaction of ethene with dilute sulfuric acid.
Since it is an element. It is 1.01g/mol as per the periodic table
The gas however H2 is diatomic which has a mass of 2.92
