Which two subatomic particles have the greatest mass?

Chemistry
1 answer:
denpristay [2]3 years ago
6 0

Answer:

PROTON AND NEUTRON

Explanation:

  • The mass of proton is : 1.67*10^{-27}kg

A proton is one of the main particles that make up the atom . The other two particles are neutron and electron. Protons are found in the nucleus of the atom.This is a tiny , dense region at the centre of the atom. Protons have a positive charge of one (+1) and a mass of 1 atomic mass unit ( amu ) , which is about 1.67*10^{-27}kg. Together with neutrons , they make up virtually all of the mass of an atom.

  • The  mass of neutron is also approximately: 1.67*10^{-27}kg but a little more than that .

Atoms of all elements - except Hydrogen , have neutrons in their nucleus . Unlike protons and electrons , these have no charge - they are electrically neutral . The mass of a neutron is slightly greater than the mass of a proton but not very significant

Gas hydrates are compact chemical structures made of natural gas and
Oksana_A [137]

Answer:


                  Option-B (water) is the correct answer.


Explanation:

                 Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.


Generally Gas hydrates have two main applications. 

                             a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor. 

                             b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.

How many moles of argon gas would be present in a 37.0 liter vessel at 45.00 °C at a pressure of 2.50 atm?
Pani-rosa [81]

Answer:

3.54 mol

Explanation:

Step 1: Given data

  • Volume (V): 37.0 L
  • Temperature (T): 45.00 °C
  • Pressure (P): 2.50 atm

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 45.00°C + 273.15 = 318.15 K

Step 3: Calculate the number of moles (n) of argon gas

We will use the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 2.50 atm × 37.0 L/(0.0821 atm.L/mol.K) × 318.15 K = 3.54 mol
