Answer:
The difference between normal salt and acid salt is that acid salt is basically made up of strong acid and also including a weak base. However normal salt is practically made up of strong base or even a weak acid and also a weak base. Acid salt or in a more logical term known as acidic salt ionises into a type of form of H + ions which is more than OH- ions, which is in a water solution. But even than normal salt ionises into a form of eqaul number of H+ ions and OH- ions in this so called water solution.
Answer: All of the above!
Explanation:
Water- moves across soil and breaks down pieces of rocks
Wind- can blow materials around, such as rocks or sand. Also it can dry out soil.
Ice- carries broken rocks or soil to different places and can cause glacier erosion.
Gravity- thinking about it, earth is the one place with gravity so if gravity changed it can cause objects to move. Also it determines the shape of the earth because the center has more gravitational pull. This gives it a very round shape.
Organisms- more animals means increase of destruction of plants, which can lead to faster erosion.
Sun- the sun is very important. If the earth didn’t get any sunlight there wouldn’t be any life on the planet itself. Which makes it lack rocks, plants, weather, and the atmosphere.
And by that point it’s just not none of the above.
The answer for this math problem must be c
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
