How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns

Explanation:

The question that cannot be answered scientifically from the given choices is "how does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns".

This problem is off the jurisdiction of natural science.

  • Scientific questions are usually empirical in nature and draws relationship between two variables.
  • Usually, one variable changes and the other is affected.
  • This problem stated is subjective and not scientific.
  • Humans have a wide range of personality traits.
  • This problem can be solved using a psychological analysis.

A sample of ammonia (NH3) gas is completely decomposed to nitrogen and hydrogen gases over heated iron wool. If the total pressu
DochEvi [55]

Answer:

539.3mmHg of H₂

179.7mmHg of N₂

Explanation:

Ammonia, NH₃, reacts completely producing N₂ and H₂ thus:

2 NH₃ → N₂ + 3H₂

<em>That means there are produced 4 moles of gases and 3 are of H₂ and 1 of N₂</em>

Total pressure (Sum of pressures of N₂ and H₂) is 719mmHg. 3 parts are of H₂ and 1 of H₂

Thus, partial pressures of the products after reaction are:

719mmHg ₓ (3 H₂ / 4) = 539.3mmHg of H₂

719mmHg ₓ (1 N₂ / 4) = 179.7mmHg of N₂
