Answer. Methane molecule is made up of five atoms; four of hydrogen and one of carbon. Carbon atom is sharing its 4 valence electrons with 4 hydrogen atoms each having 1 electron.
Explanation:
Dalton model of atom said that the matter is made up of smallest indivisible particle that is an atom. From which he predicted that methane molecule will be made up one carbon atom and 4 hydrogen atoms.
Quantum model of atom described the structure of atom with the help of four quantum numbers. These number explained the position, magnetic character and spin of electrons inside the atom. and further explained the sharing of electron between one one carbon and 4 hydrogen atoms.
Hence from these two models we can predict that methane molecule is made up atoms with sharing of electrons.
Answer:
60000J
Explanation:
Given parameters:
Mass of car = 1200kg
Speed = 10m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy is given as:
Kinetic energy = 
m v²
Now insert the parameters and solve;
m is the mass
v is the velocity
Kinetic energy = x 1200 x 10² = 60000J
My answer to the question above is not the best example but I hope it will help you. <span>The Arrhenius model says that acids always contain H+ and that bases always contain OH-. </span>
<span>The Bronsted-Lowry model thinks of acids as being proton donors and proton acceptors, so bases no longer need to contain OH-, and acids donate a proton to water forming H3O+. </span>
<span>Lewis acids are electron pair acceptors, and Lewis bases are electron pair donors. For instance, H+ + OH- => H20. H+ has no electrons, so when it bonds to the Oxygen, it gains an electron pair. OH- "loses" an electron pair.</span>
Answer:
On the periodic table, there are two numbers for every element: the atomic number and the atomic weight.
The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number.
For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine.
