Cations have more protons than electrons, Anions result when atoms gain an electron.

<h3>What are electrons ?</h3>

The electron, a subatomic particle, has a negative one elementary charge electric charge. The electron, a member of the first generation of the lepton particle family, is usually regarded as an elementary particle because it has no known components or substructure.

<h3>How electrons are in an atom ?</h3>

A few straightforward rules can be used to calculate the quantity of protons, neutrons, and electrons present in an atom. The atomic number and the number of protons in the atom's nucleus are equal (Z). A neutral atom has the same number of protons and electrons as protons.

Around the nucleus, electrons are positioned in several shells. Only a fixed amount of electrons can fit in each subsequent shell. Filling begins with the innermost shell.

Suppose that a sample of gas occupies 187 mL
drek231 [11]

Answer:

V2 = 90.7 mL

Explanation:

pressure and volume are inversely proportional, if the pressure is increased, the volume will decrease. In an isothermal process:

p1V1 = p2V2

V2 = p1V1/p2 = (277 torr×187 mL)/571 torr

V2 = 90.7 mL

1. A mixture contains 8.00 g each of O2, CO2, and SO2 at STP. Calculate the volume of this mixture. Which of the gases would exe
Gekata [30.6K]

Answer:

Explanation:

mole of O₂ = \frac{8}{32}

= .25 moles

mole of CO₂

= \frac{8}{44}

= .1818 moles

moles of SO₂

\frac{8}{64}

= .125 moles

Total moles of gas

= .5568 moles.

total volume of gas mixture

= 22.4 x .5568 liter ( volume of one mole of any gas = 22.4 liter)

= 12.47 liter.

gas will exert partial pressure according to their mole fraction

gas having greatest no of moles in the total mole will have greatest mole fraction so

O₂ will have greatest partial pressure.

Define the following solar features in detail: Solar flare: Sunspot Prominence:
Over [174]
Solar flare: a brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth, as with radio frequency communications and power line transmissions.

Sunspot Prominence: It is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. It is similar to a Solar Flare
