Answer:
Love Waves
Explanation:
I am pretty sure of this, have a great day
The type of earthquake waves that moves sideways on Earth's surface like a snake is the Love waves.
What is earth quake?An earth quake is said to occur when the earth is vibrating as a result of the transmission of siesmic waves.
The type of earthquake waves that moves sideways on Earth's surface like a snake is the Love waves. This is because, all the other types of earthquakes move in other patterns but only the Love waves move in sideways patterns.

Ocean water density varies more at the the poles throughout the year than at the equator.
Lesson 2.08
True
False
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.

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?
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.

How many moles each element are in a mole of methane?
[tex] \large \mathcal{ANSWER}[/tex]
This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams. A mole can be thought of as two bags of different sized balls. One bag contains 3 tennis balls and the other 3 footballs.
Samples of helium (He), nitrogen (N 2 ), and methane (CH 4 ) are at STP. Each contains 1 mole or 6.02 × 10 23 particles. However, the mass of each gas is different and corresponds to the molar mass of that gas: 4.00 g/mol for He, 28.0 g/mol for N 2 , and 16.0 g/mol for CH 4 .

how do we know that all the continents were all together at one point in time. writing prompt and it has to be at least 7 sentences
Answer:
We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.

information from a broadcasting station in new york to a receiving station in
london.
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.

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).
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
