Given the balanced equation representing a reaction:4NH3 + 5O2 ==>4NO + 6H2O
What is the minimum number of moles of O2 that are needed to completely react with 16 moles of NH3?
(1) 16 mol (3) 64 mol
(2) 20. mol (4) 80. mol

Answers

Answer 1

Answer: 4 NH₃ + 5 O₂ = 4 NO + 6 H₂O

4 moles NH₃ --------- 5 moles O₂
16 moles NH₃ -------- ? moles O₂

moles O₂ = 16 * 5 / 4

moles O₂ = 80 / 4

= 20 moles of O₂

Answer (2)

hope this helps!

What is the difference between the orbital periods of Mercury and Earth?Select one:
a. 0.61 years
b. 0.76 years
c. 1.24 years
d. 1.39 years

Answers

The correct answer is B. The difference between the orbital period of planets Mercury and Earth is 0.76 years. The orbit of mercury is the most eccentric among the planets in the Solar system and the smallest planet. It has an orbital period of 88 Earth days.

Answer:

b. 0.76 years

Explanation:

Mercury is the closest planet to the Sun and the Earth is the third planet from the Sun.

The orbital period of the Earth is 1 year.

Orbital period of the Mercury is 88 days = 0.24 years (Earth years)

Thus, the difference between the orbital periods of Mercury and Earth is

1 year - 0.24 years = 0.76 years

Thus, the correct option is b.
