Answer:
the mirror is 12 cm away from the image
Explanation:
; the image will be virtual and it will form at 12 cm distance behind the mirror.
First, since l = n-1,
5,4,-5,1/2 and 2,1,0,1/2 are the only answer choices left.
Next, since ml = -l to l,
2,1,0,1/2
is the answer because in 5,4,-5,1/2, the ml value of -5 is not in the range of -4 to 4, as notes by the value 4 for l.
Na2S2O3(aq) + 4Cl2( g) + 5H2O = 2NaHSO4(aq) + 8HCl(aq)
1)How many moles of HCl can form from 0.21 mol of Cl2?
0.21 mol Cl2 ( 8 mol HCl / 4 mol Cl2 ) = 0.42 mol HCl
2)How many moles of H2O are required for the reaction of 0.18 mol of Cl2?
0.18 mol Cl2 ( 5 mol H2O / 4 mol Cl2 ) = 0.225 mol H2O
3)How many moles of H2O react if 0.50 mol HCl is formed?
0.50 mol HCl ( 5 mol H2O / 8 mol HCl ) = 0.3125 mol H2O
Answer:
Explanation:
functional groups are specific substituents or atoms within molecules that brings about chemical reactions of those molecules. There is the same or similar chemical reaction in compounds with the same functional groups.
1.)The functional group in Alkyl halides is halogen atom whille
The functional group in Alcohols have
is OH group. There is a double bond in HX or an HOH molecules.
2.)The functional group of carboxylic acid is an organic compound is carboxyl functional group.While The functional group in amine contains a basic nitrogen atom with a lone pair of electrons.
3.)The functional group in ester is a carboxylic acid derivative that is analogous to the Amides
4.) A carboxylic acid has carboxyl functional group. However the hydrogen of the hydroxyl group is can be ionized. In an ester, there is a replacement of hydrogen of acarboxylic acid group by an alkyl group
