london.
Answers
Answer:
Explanation:
Satellite acts as a relay station for earth sources. A transmission station sends the information to the satellite, which in turn retransmits to the receiving stations. The original signal being transmitted from the earth station to the satellite is called uplink of 6 GHz The retransmitted signal from the satellite to the receiving station is called downlink of 4 GH frequency. The transponder is the transmitter-receiver combination in a transponder.

Shown above is information about the dissolution of AgCl(s) in water at 298K. In a chemistry lab a student wants to determine the value of s, the molar solubility of AgCl, by measuring [Ag+] in a saturated solution prepared by mixing excess AgCl and distilled water. How would the results of the experiment be altered if the student mixed excess AgCl with tap water (in which [Cl−]=0.010M) instead of distilled water and the student did not account for the Cl− in the tap water?
Answers
Answer:
Value for K would be too small. Less AgCl would dissolve due to the common ion effect due to the presence of Cl- in the water.
Explanation:
Think of this through the lenses of a shifting problem. Cl- ions are a product in this situation and increasing its concentration would shift the reaction back to the solid AgCl. In this specific case, due to Cl- ions, AgCl would dissolve less to maintain equilibrium and as a result, the concentrations of Ag+ and Cl- ions would be lower than normal making a smaller K value.
In the solution of AgCl in tap water, the dissociation constant K has been decreased.
The dissolution of silver chloride in water results in the formation of silver ions and chloride ions.
The dissociation constant has been the amount of compound that has been dissociated into the constituent ions at equilibrium.
Dissociation constant for AgClThe dissociation constant has been dependent on the number of ions in the solution that has been present.
The common ion effect has been defined as the change in the dissociation constant for the compound with the presence of common ions in the solution.
The dissociation of AgCl in tap water has been resulted with presence of Cl ions in the solution. There has been early reach to the equilibrium in tap water.
Thus, with the solution of AgCl in tap water, the dissociation constant K has been decreased.

Answers
Answer:
true
Explanation:
i go to k12
Ocean water density varies more at the the poles throughout the year than at the equator. Therefore, the given statement is true.
What is density?Density is the mass of a specific material per unit volume. d = M/V, in which d is density, M is weight, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density. For instance, whereas Earth has a density of 5.51 grams, water has a density of 1 milligrams.
Particle density, which is typically represented as n, describes the number of particles per volume instead of the density of either a single particle. Ocean water density varies more at the the poles throughout the year than at the equator.
Therefore, the given statement is true.

Which is the correct formula for the ionic compound that results from these two atoms? PLS HELP!!!
Answers
Answer:
If I am not wrong is C x2y5
Explanation:
The concept of valency is used here to determine the formula of the ionic compounds. The number of valence electrons in 'X' is 2 and that of 'Y' is 5. The formula is X₃Y₂. The correct option is D.
What is an ionic compound?The crystalline solids which are formed by neatly packed ions of opposite charges are defined as the ionic compounds. These compounds are formed by the combination of metals with non-metals.
The combining capacity of an element is given by valency. The elements belonging to the same group have the same valency. It is related to how many electrons are in the outer shell.
Here the number of valence electrons in 'X' = 2
The number of valence electrons in 'Y' = 5
The element 'X' need 6 electrons to attain the octet and 'Y' needs 3 electrons to attain the octet.
X - 6
Y - 3
The formula of the ionic compound is X₃Y₂.

What differentiates solid, liquid and gas phases from each other? As part of your response discuss how the energy of attraction between particles compares with their energy of motion (i.e. their kinetic energy, Ek), the distances between particles, their compressibility and their relative viscosities (i.e. resistance to flow).
Answers
Answer:
I hope this helps
Explanation:
Solid = low kinetic energy, close distance between particles, not compresssible, higher flow resistance
Liquid = lower kinetic energy than gases, closer distance between particles than gases, relatively compresssible, high flow resistance than gases
Gas = high kinetic energy, far distance between particles, compresssible, low flow resistance
