Answer: A
Explanation: Beach deposits and wind blown deposits generally show good sorting because the energy of the transporting medium is usually constant.
Answer: 3 O2
Explanation: This is a combustion reaction. A hydrocarbon reacts with oxygen gas to produce CO2 and H2O.
C2H5OH + 3 O2 => 2 CO2 + 3 H2O
Due to high evaporation rate and low precipitation, the oceanographer to find the highest salinity at the tropics.
<h3>What is salinity?</h3>
Salinity refers to the salt content of a water body such as rivers and oceans.
Oceans and seas have high salinity due to the presence of many dissolved minerals.
Different area of the oceans have different salinities.
Salinity is highest at the tropics and equator due to high rate of evaporation and low precipitation.
Therefore, the oceanographer to find the highest salinityat the tropics.

Answer:
Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.
Explanation:
The number of formula units of NaCl are 7. In 1 mole of NaCl there are 
formula unit are present.
Thus, 1 formula unit will be there in 
moles.
and, 7 formula unit will be there in 
moles.
There is 1 mol of Cl present in 1 mol of NaCl. thus, of Cl will be there in mol of NaCl.
Converting number of moles into number of atoms as follows:
In 1 mole of a substance there are atoms of chlorine thus, in mol there will be 7 atoms of chlorine.
Therefore, number of atoms of chlorine will be 7.
