different parts of the sum rotate at different rates
Answer:
In the arrangement of particles within any atom, the outermost sort of particle is always the electron.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol= e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
The stoichiometry of the reaction is 5 mols of O2 produces 4 mols of CO2.
1 mol at STP is equivalent to 22.4 liters.
So, 5*22.4 liters of O2 produces 4*22.44 liters of CO2
Then 60 liters of O2 produces 60*4/5 = 48 liters of CO2
Compound A : SnCl2
the mass ratio of Cl and Sn: 71 g Cl/ 119 g Sn = 0.579 g Cl/ 1 g Sn
Compound B: the ratio of mass of chlorine per 1 g Sn is twice the ratio of chlorine per 1 g Sn in compound A => 1,194 g Cl/ 1 g Sn = 142,086 g Cl/ 119 g Sn
=> the number of chlorine/ 1 atom Sn = 142.086/ 35.5 = 4.
=> the formula of B: SnCl4
<h2>Decomposition</h2>
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.
Since there is only one reactant and it is broken into smaller components,
it is not a synthesis reaction.
A decomposition reaction is a type of chemical reaction in which one reactant yields two or more products.
Since in our question,there is one reactant and it is broken to yield two products,it is a decomposition reaction.
