What is true of both galvanic and electrolytic cells?
A. Reduction happens at the cathode.
B. They are spontaneous. .
C. They are nonspontaneous.
D. Oxidation happens at the cathode.
Answer:
reduction happens at the cathode
Explanation:
Just took the test.
Reduction happens at the cathode. Hence, option A is correct.
What is an electrolytic cell?An electrolytic cell converts electrical energy into chemical energy or vice versa.
Oxidation-reduction reactions are balanced by two half overall chemical equations into an oxidation equation and a reduction equation.
Hence, reduction happens at the cathode in both galvanic and electrolytic cells.

Similarities between sliding and fluid friction
Match the intermolecular force with the physical property that will result
Answer:
Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase. Hope this is what your looking for!

What is atomic mass made of?
Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

What is the purpose of a unit conversion?
O
A. To change an amount in one unit to its equivalent amount in
another unit
B. To express a scientific expression in a general form all scientists
can understand
C. To express the amount of something in terms of its number of
smallest units
D. To keep track of the units associated with a number throughout an
equation
Answer:
A
Explanation:
A conversion factor is used to change the units of a measured quantity without changing its value.
Unit conversion is very important because the rest of the world other than three contries uses the metric system. So, converting unitsis important in science because it uses the metric system. The metric system are measurements like cm, m, l, mL, etc.

Which choices are layers of the atmosphere?
Select the five correct answers.
Thermosphere
Meteorosphere
Croposphere
Stratosphere
Mesosphere
Danosphere
Exosphere
Troposphere
Answer:
Mesosphere
Stratosphere
Thermosphere
Troposphere
Exosphere
Explanation:
The exosphere refers to the farthest region of the atmosphere that gradually fades into space.
The troposphere is the lowest layer of atmosphere. It is the layer where weather changes occur.
The thermosphere is right above the mesosphere but just below the exosphere. It is the layer where photoionization/photodissociation of molecules occurs thereby creating ions. This largely owes to interaction of molecules in this layer with ultraviolet radiation.
The stratosphere is composed of gases. Prominent among them is ozone which serves as a blanket against the sun's ionizing radiation.
The mesosphere lies above the stratosphere but just below the thermosphere. Temperature decreases steadily with height in the mesosphere.
THIRTY POINTS I NEED HELP HURRY What is the volume of the cone?
Answer:
V=πr2h 3
Explanation: I would give more but need more i information
Answer:there u go
Explanation:The volume V of a cone with radius r is one-third the area of the base B times the height h . Note : The formula for the volume of an oblique cone is the same as that of a right one. ... If the heights of a cone and a cylinder are equal, then the volume of the cylinder is three times as much as the volume of a cone

Answer:
The answer to your question is A - electrons
Explanation:
To be honest it's pretty obvious, none of the other things could possibly come with valence behind it so electrons is the only logical answer.
Answer:
A. electrons
Explanation:
The valence electrons on the valence shell which is the last layer of electrons are the same for atoms in the same column.
