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...

Answer is: mass of calcium hydroxide is 46.98 grams.
Balanced chemical reaction: CaO + H₂O → Ca(OH)₂.
m(CaO) = 35.55 g.
n(CaO) = m(CaO) ÷ M(CaO).
n(CaO) = 35.55 g ÷ 56 g/mol.
n(CaO) = 0.634 mol; limiting reactant.
m(H₂O) = 125 mL · 1.000 g/mL.
m(H₂O) = 125 g.
n(H₂O) = 125 g ÷ 18 g/mol.
n(H₂O) = 6.94 mol.
From chemical reaction: n(CaO) : n(Ca(OH)₂) = 1 : 1.
n(Ca(OH)₂) = 0.634 mol.
m(Ca(OH)₂) = 0.634 mol · 74.1 g/mol = 46.98 g.

Answer:
[NaOH} = 0.4 M
Explanation:
In a reaction of neutralization, we determine the equivalence point of the titration. In this case, we have a strong base and a strong acid.
(H₂SO₄, is considered strong, but the first deprotonation is weak)
2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
As we have 2 protons in the acid, we need 2 OH⁻ from the base to form 2 molecules of water.
In the equivalence point we know mmoles of base = mmoles of acid
Let's finish the excersise with the formula
25 mL . M NaOH = 28.2 mL . 0.355M
M NaOH = (28.2 mL . 0.355M) / 25 mL → 0.400
