Which statement best describes the weather shown by the purple combination of semicircles and triangles on a line on a weather m

ap?
A warm front brings drizzly weather.

An occluded front can cause light to heavy precipitation that may last several days.

A cold front can cause heavy rain, thunder, and lightning.

A stationary front may produce rainy or snowy weather for several days.

What is the value of the equilibrium constant for this redox reaction?
aivan3 [116]
Correct  answer: Option D, <span>K = 5.04 × 10^52
</span>
Reason:
We know that, 
Ecell = \frac{0.0592}{n}log(K),
where n = number of electrons = 2 (in present case)
K = equilibrium constant.

Also, Ecell = <span>+1.56 v

Therefore, 1.56 = </span>\frac{0.0592}{2}log(K)
Therefore, log (K) = 52.703
Therefore,  K = 5.04 X 10^52

BRAINLIEST AND 30 POINTS! concept map for four types of intermolecular forces and a certain type of bond is shown.
Sphinxa [80]

D represents ion-dipole forces that are stronger than the force C.

Explanation:

D represents the ion-dipole force.

C represents the H-bonding forces.

ion-dipole force is a force that is due to electrostatic attraction and has a dipole between an ion and a neutral molecule.

It is electrostatic in nature.

A hydrogen bond is the force between the hydrogen with the electro negative atom of one molecule, to electro negative atom of some other molecule. such as: O, F, N

Ion dipole force is stronger than the H-bonding.

Why did we have you determine the reaction rate using reactant consumed per unit of time instead of product formed per unit of t
Vsevolod [243]

Answer:Rate of reaction can be determined in terms of concentration of reactants consumed or concentration of product formed per unit time

Explanation: For the reaction below

A ===>B

The reactant is A while the product given is B.

Reaction rate = Δ[B]/Δt = -Δ[A]/Δt

The concentration of A will decrease with time while the concentration of B will increases with time.

The negative sign in -Δ[A]/Δt is to convert the expression to positive since the change will always be negative (decreases)

Espresso Coffee House is designing a coffee mug that keeps liquids hot. The research department tested several different materia
raketka [301]

Answer:

This question is incomplete

Explanation:

This question is incomplete because the result of the described experiment would have better determined the type of scientific explanation to profer. However, the type of material that will preserve the relative hotness or temperature of the hot coffee for the longest time will be a material than can resist heat transfer. These materials tend to keep hot substances hot by not allowing the heat of the coffee to be conducted or pass through it. These materials are mostly insulators or made by placing an insulator between two heat conductors.

Generally, heat is usually transferred from a region of higher concentration to a region of lower concentration, hence when the heat is denied of this transfer, the heat will remain trapped in the "heat-donor" substance (in this case the hot coffee). Thus, the material chosen (A, B or C) will be the material that resists heat transfer the most based on the explanation above.
