Answer:
Evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as they help in formation of clouds and precipitation
Explanation:
Evaporation:
It is the process of formation and transfer of the water vapor from the surface of the liquid into the atmosphere.
Transpiration:
It is the process of transfer of the water vapors in the atmosphere from the pores present in the leaves of the plants.
The water is carried from the ground through the stems to the leaves.
The major difference between the evaporation and transpiration is that the evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as these process helps in transfer of the surface water into the atmosphere, which helps in formation of clouds and precipitation.
Ask your teacher for a formula sheet so the way you would know the formula for volume then you can try to solve it hope that helps
Ionic compounds contain both cations and anions in a ratio that results in no net electrical charge
Answer:
(a). 4
(b). 1 triple bond.
(c). 1
(d). 1 ring.
Explanation:
Without mincing words let's get started. So, we have that the chemical formula for the compound is C8H10. So, we are given from the question that lindlar's catalysts which is represented by H2 / Pd / CaCO3 and used in hydrogenation especially from alkyne to alkene.
(a). The degrees of unsaturation in the unknown can be calculated as;
[ (2 × Number of carbon atoms) + (2 ) - (number of Nitrogen atoms) - (number of hydrogen atoms) - number of halogens) ÷ 2
= [(2 × 8) + 2 - 0 - 10 - 0 ] ÷ 2.
=( 16 + 2 -10 ) ÷ 2.
= ( 18 - 10) ÷ 2 = 8/2 = 4.
(b). The number of triple bonds is 1 because we are given from the question that "On catalytic hydrogenation over the Lindlar catalyst, 1 equivalent of hydrogen is absorbed" and this is the work of the catalyst to prevent the alkyne from going to alkane straight.
(c). The number of double bonds is 1 because we are given from the question that "On hydrogenation over a palladium catalyst, 3 equivalents of H2 are absorbed".
(d)The number of rings is 1
