Answer:
[OH-] = 0,071 mol/L
Explanation:
pOH = -log[OH-]
[OH-] = 10^-pOH = 10^-1.15 = 0,071 mol/L
Glucose is C6H12O6.
so u simply need to add the individual masses of 6 carbons, 12 hydrogens and 6 oxygens.
the molecular mass of carbon is 12 but if u take it as 40..
them it would be..
6x40+12x1+6x16= whatever u get in your calc. ;)
Answer:
Selective Breeding
Weeds are bad,
But why is this so?
Just like grass,
They too grow.
Weeds are disliked,
Like the drink that's spiked.
But why is this so?
Who's to say they shouldn't grow?
The weed is unwanted,
Like a murderer hunted.
But what crime did it commit?
Why should it not, be free to sit?
Thickly they may grow,
But grass even more so.
Who's to say they should not grow?
Why should their seed not be sow?
Weeds are bad,
But why is this so?
Just like grass,
They too grow.
If all things living, were for cared,
The land we own, for all shared.
The weed let live,
And life not carefully selected by- siv.
Selective breeding is unfair,
No better than plain warfare...
Explanation:
Answer:
1. 2,2-dimethyl-propanoic acid
2. 1,3-pentanediol
3. 4-chloro-3-ethylbutanal
Explanation:
1. The carbon in the carboxyl group is assigned number 1 by convention then counted chronologically as you move outwardly in the longest chain of the acid. The two methyl groups therefore occur on the second carbon.
2. There are two hydroxyl group on two different carbons. Two hydroxyl groups mean it is not an alcohol but a diol.
3. The carbon in the carbonyl group is assigned number 1 by convention then the carbons are numbered in chronological order as you mvoe outwardly on the longest chain.
