Answer:
A. Up
B. Out
C. Out
D. To equilibrum
Explanation:
a. The reaction in an exothermic reaction so this means heat is given off. If the cylinder is thin enough heat will transfer to the water bath
b. Since the products will create heat which will increase pressure, the piston in an attempt to maintaining a constant pressure will move up to accommodate building pressure.
c. Heat will flow out of the gaseous mixture as this reaction creates heat as a product as well
d. Heat will flow out in the capacity to create an equilibrium with the water bath that it is in.
Answer:
Mass of sodium hydroxide needed = 28.2 g
Explanation:
Given data:
Mass of sodium hydroxide = 80 g
Mass of sodium sulfate produced = 142 g
Mass of sodium hydroxide needed = ?
Mass of sodium sulfate produced = 50 g
Solution:
Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x
142 g/ 80 g = 50 g / x
x = 50 g × 80 g / 142 g
x =4000 g/ 142
x = 28.2 g
Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays
This is further explained below.
<h3>What is
electromagnetic radiation?</h3>
Parameters
Frequency =107 100 000 hertz
Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m
Energy = 3.97 * 10 -19 J/ photon.
Generally, the equation for Wavelength is mathematically given as
λ = h c / E
Therefore
λ =6.626 * 10-34 * 3 * 108 / (3.97* 10 -19 J)
λ =5 * 10-7 m
In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays

Answer:
0.6 moles NH₃
Explanation:
The reaction that takes place is:
First we <u>determine the limiting reactant</u>:
- 0.35 mol N₂ would react completely with (3*0.35) 1.05 moles of H₂. There are not as many H₂ moles, so H₂ is the limiting reactant.
Then we <u>convert H₂ moles (the limiting reactant) to NH₃ moles</u>, keeping in mind the <em>stoichiometry of the reaction</em>:
- 0.90 mol H₂ *
= 0.6 moles NH₃
Explanation:
The given data is as follows.
Solvent 1 = benzene, Solvent 2 = water
= 2.7, 
= 100 mL
= 10 mL, weight of compound = 1 g
Extract = 3
Therefore, calculate the fraction remaining as follows.
![f_{n} = [1 + K_{p}(\frac{V_{S_{2}}}{V_{S_{1}}})]^{-n}](https://tex.z-dn.net/?f=f_%7Bn%7D%20%3D%20%5B1%20%2B%20K_%7Bp%7D%28%5Cfrac%7BV_%7BS_%7B2%7D%7D%7D%7BV_%7BS_%7B1%7D%7D%7D%29%5D%5E%7B-n%7D)
= ![[1 + 2.7(\frac{100}{10})]^{-3}](https://tex.z-dn.net/?f=%5B1%20%2B%202.7%28%5Cfrac%7B100%7D%7B10%7D%29%5D%5E%7B-3%7D)
= 
= 
Hence, weight of compound to be extracted = weight of compound - fraction remaining
= 1 -
= 0.00001
or, = 
Thus, we can conclude that weight of compound that could be extracted is .
