Answer:
8.00L of ammonia can be produced
Explanation:
The reaction is:
N₂(g) + 3H₂(g) → 2NH₃(g)
<em>Where 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.</em>
Avogadro's law states that, under constant pressure and temperature, equal volumes of gases contains equal number of moles.
As in the reaction conditions are mantained at STP (Pressure and temperature are constant) you can say of the reaction that:
<em>1 liter of nitrogen reacts with 3 liters of hydrogen to produce 2 liters of ammonia</em>
<em />
Thus, if 12.0L of hydrogen reacts and 3L of hydrogen produce 2L of ammonia, liters of ammonia produced are:
12L H₂(g) ₓ (2L NH₃(g) / 3L H₂(g)) =
<h3>8.00L of ammonia can be produced</h3>
Explanation:
“The isomers butane and methyl propane have the same molecular formula and different properties”, this is because structural isomers usually have different properties to their parent.
1. alizarin yellow R, color change at pH 10-12
2. thymol blue, color change at pH 2-4
3. methyl red, color change at pH 3-5
4. phenolphthalein, color change at pH 8-10
<span>5. bromothymol blue, color change at pH 6-8
These are the list of indicators that we have to choose from them and the correct answer will be 5) Bromothymol blue, due to color change at pH 6-8
Due to both HI is strong acid and Ba(OH)</span>₂ is strong base so the formed salt BaI₂ will has pH = 7 and the equivalence point will be 7 so it will be in the effective range of Bromothymol blue
He made a new approach when he discovered magnetism and electricity.
7. a. I
8. c. 75 g/ml
9. b. .25g/cm3
10. b. the density decreases
