Answer: The molarity of silver nitrate in the diluted solution is 0.015 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the dilution law,
where,
= molarity of concentrated solution = 0.150 M
= volume of concentrated solution = 10.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 100.0 ml
Thus the molarity of silver nitrate in the diluted solution is 0.015 M
Answer:
Old and inefficient mining smokestacks contaminate the soils around abandoned mine sites.
Explanation:
A smokestack, is a very tall channel commonly used in many instances to release gases produced by combustion processes directly into the air. These high towers are aimed at dispersing the gaseous pollutants over a wider area thereby minimizing their impact.
Old and inefficient smokestack do not contaminate the soil since they are very high towers that discharge gases directly into the atmosphere. Hence they are not part of the sources of soil contamination in abandoned mines.
Answer:
The partial pressure of SO₃ is 82.0 atm
Explanation:
The equilibrium constant Kp is equal to <em>the equilibrium pressure of the gaseous products raised to the power of their stoichiometric coefficients divided by the equilibrium pressure of the gaseous reactants raised to the power of their stoichiometric coefficients</em>.
For the reaction,
2 SO₂(g) + O₂(g) → 2 SO₃(g)
Answer:
183.6kg
Explanation:
Given parameters:
Specific heat of the substance = 0.246J/g°C
Change in temperature = 15.5°C
Amount of energy released = 700J
Unknown:
Mass of the sample = ?
Solution:
To solve this problem we used the energy equation:
H = m c Δt
H is the energy released
m is the unknown mass
c is the specific heat
Δt is the change in temperature
Now insert the parameters and find m;
700 = m x 0.246 x 15.5
700 = 3.8m
m = 183.6kg
