The anode compartment contains [SO2-4] with a concentration of 1.30 m, this is in equilibrium with PbSO4 (s). The dissociation of PbSO4 is:
PbSO4 + H2O ---> Pb 2+ + SO4 2-
The Ksp of PbSO4:
Ksp = [Pb2+] [SO4-2]

A map is a symbolic representation of selected characteristics of a place or a given location. It present information about the world in a simple, visual way.
Several key features must be included on a map to aid the viewer in understanding the communication of a given map. They include;
- Legend; it serves as the decoder for the symbology in the data frame.
- Scale; explains the relationship of the date frame compared to the real world.
- Tittle; It instantly gives the viewer a succinct description of the subject matter of the map.
- Compass rose or North arrow
- Data frame, and
- Citation among others.
Answer:
Multiplication Associative property. because the parenthesis move and the equation is multiplication.
Explanation:
Avogadros Law if pressure is the result of collision, molecules colliding with the wall of the container and every time they collide they exert a force. pressure is the result of the force and area. if we add more gas particles you are going to see more collisions with the wall of container the gas particles will exert a greater over the same exact area. they have a directly proportional relationship. Pressure and volume, pressure=force/area, if we have a container with the same number of particles but of different particles, the smaller volume containers will have smaller area and more collision increasing pressure so they have an inversely proportional relationship. Pressure and temperature, pressure=Force/area force is going to change not the area, when we heat up the molecules up they end up moving faster colliding with the walls of the container more often exerting a greater force. now Volume and temperature, if we heat the gas particles, they move more rapidly gas expands!.
Answer:
0.205M
Explanation:
Molarity is an unit of concentration used in chemistry defined as the ratio between moles of solute (In this case, LiF) and liters of solution.
To solve this question, we must find the moles of LiF and the liters of the solution:
<em>Moles LiF -Molar mass: 25.939g/mol-:</em>
2.39g * (1mol / 25.939g) = 0.0921moles
<em>Liters solution:</em>
450mL * (1L / 1000mL) = 0.450L
Molarity is:
0.0921 moles / 0.450L =
<h3>0.205M</h3>
