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:
Hydrogen reacts with oxygen to form water based on the following equation:
2H2 + O2 ..............> 2H2O
This means that 4 grams of hydrogen are required to react with 32 grams of oxygen to release 36 grams of water.
We need to calculate how munch oxygen is needed to react with 4.8 grams of hydrogen. We can do this using cross multiplication as follows:
amount of oxygen = (4.8x32) / 4 = 38.4 grams
This means that we have no limiting reagent here and both reactants will completely react.
We know that 4 grams of hydrogen are required to produce 36 grams of water. Therefore:
amount of water produced from 4.8 grams of hydrogen = (4.8 x 36) /4 = 43.2 grams
