Answer:
10 molecules of NH₃.
Explanation:
N₂ + 3H₂ --> 2NH₃
As the N₂ supply is unlimited, what we need to do to solve this problem is <u>convert molecules of H₂ into molecules of NH₃</u>. To do so we use the <em>stoichiometric coefficients</em> of the balanced reaction:
- 15 molecules H₂ *
= 10 molecules NH₃
10 NH₃ molecules could be prepared from 15 molecules of H₂ and unlimited N₂.
Answer:
Explanation:
The hydrostatic pressure is defined as the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity, the formula is:
P = ρgh + P₀
Where:
ρ is density (1020kg/m³)
g is gravity (9,8m/s²)
h is depth (150m)
P₀ is the atmspheric pressure (101325 Pa)
Replacing, P = 1'600'725 Pa

Suspension. The particles are big enough for the eye to see, and will separate if left sitting.
Answer: The mass of 405 ml of cresol is 415 grams
Explanation:
Density is defined as the mass contained per unit volume.
Given : Density of cresol = 1024 g/L
Volume of cresol = 405 ml = 0.405 L ( 1L=1000ml)
Putting in the values we get:
Thus mass of 405 ml of cresol is 415 grams
