Answer: option B. 0.020 mole
Explanation:Please see attachment for explanation
Answer:
53.4%
Explanation:
N₂ + 3H₂ → 2NH₃
Given that:
26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃
Then:
The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)
= 13.05 mol of H₂
The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)
= 8.697 mol of NH₃
The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃
The percent yield = actual yield/ theoretical yield * 100%
The percent yield = ( 79.0 g/ 148.1 g )* 100%
The percent yield ≅ 53.4 %
The heat transfer will only occur in setup 2 and heat will only flow from C to D.
<h3>
Heat energy</h3>
In a mixture between two substances of different temperatures, there is heat transfer, in which the one with a lower temperature receives this heat and the one with a higher temperature loses the heat.
In a system, the value of heat lost and received is <u>equal</u>.
So, heat will only flow in setup 2 since it is the only one that has two bodies with different temperatures, and it will flow from C to D because C has a higher temperature.
The representation of heat transfer can be done as follows:
C ⇒ D

Explanation:
Other important behaviors of gases explained by the Kinetic Molecular Theory are effusion and diffusion. Effusion is the rate at which a gas escapes through a small hole in a container. Diffusion is the rate at which a gas travels across a room. Both of these phenomena are illustrated by the following figure.
Answer:
C
Explanation:
The phosphate group PO4 is bonded covalently (bond between two non metals). While the sodium being bonded to the phosphorus atom is an ionic bond (bond between a metal and a non metal)
