<u>Answer:</u> Volts is the unit used to measure cell potential.

<u>Explanation:</u>

Units is defined as the standard which is used to make comparisons between the measurements.

<u>For Example:</u> Meter is the unit used to measure length, Liters is the unit used to measure volume etc...

E_{cell} is defined as the EMF of the cell. It is the energy provided by a cell per coulomb of charge that passes through it. It is measured with the unit of Volts (V).

Hence, volts is the unit used to measure cell potential.

In a percentage composition investigation a compound was decomposed into its elements: 20.0 g of calcium, 6.0 g of carbon, and 2
inysia [295]

The percentage composition of this compound : 40%Ca, 12%C and 48%O

<h3>Further explanation</h3>

Given

20.0 g of calcium,

6.0 g of carbon,

and 24.0 g of oxygen.

Required

The percentage composition

Solution

Total mass of compound :

=mass calcium + mass carbon + mass oxygen

=20 g + 6 g + 24 g

=50 g

Percentage composition :

  • Ca-calcium

\tt \dfrac{20}{50}\times 100\%=40\%

  • C-carbon

\tt \dfrac{6}{50}\times 100\%=12\%

  • O-oxygen

\tt \dfrac{24}{50}\times 100\%=48\%

PV=mRT
coldgirl [10]

Answer:

The answer to your question is: P = 419933.5 Pa

Explanation:

Data

R = 0.287 KJ/Kg°K = 287 J/Kg°K

mass = 2 kg

T = 35 °C = 308°K

Container = 0.750 meters each side

Volume = l x l x l

             = 0.750 x 0.750 x 0.750

            = 0.421 m³

P = mRT / V

P = (2)(287)(308) / 0.421

P = 176792 / 0.421

P = 419933.5 Pa

Excitation and relaxation of electrons in what element are responsible for most of the light reaching Earth from the Sun? A) Arg
vfiekz [6]
The answer here is B: Helium.

As many stars, the sun is largely composed of hydrogen and helium. The sun is able to give off radiant energy through the nuclear fusion process. This involves the process by which hydrogen isotopes fuses to create one helium atom and then creates radiant energy that travels to Earth.

The atomic number of Re is 75. The atomic mass of one of its isotopes is 186. How many neutrons are in an atom of this isotope?
USPshnik [31]

Answer:

B.111

Explanation:

Atomic mass = number of protons(or atomic number) + number of neutrons

186 = 75 + number of neutrons

number of neutrons = 186 -75 = 111
