Bingel [31]2 years ago

Correct option:

Entropy is used to calculate information gain.

What is entropy?

  • Entropy is the measure of data's uncertainty or randomness; the greater the randomness, the higher the entropy. Entropy is used by information gain to make choices. Information will increase if the entropy decreases.
  • Decision trees and random forests leverage information gained to determine the appropriate split. Therefore, the split will be better and the entropy will lower the more information gained.
  • Information gain is calculated by comparing the entropy of a dataset before and after a split.
  • Entropy is a way to quantify data uncertainty. The goal is to maximize information gain while minimizing entropy. The method prioritizes the feature with the most information, which is utilized to train the model.
  • Entropy is actually used when you use information gain.

In the arrangement of particles within any atom, the outermost sort of particle is always the:________
photoshop1234 [79]

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

In the following combustion reaction of acetylene (C2H2), how many liters of CO2 will be produced if 60 liters of O2 is used, gi
Zielflug [23.3K]
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

Two compounds contain only tin and chlorine. the ratio of the masses of chlorine combined with 1.00g of tin in the two compounds
Nesterboy [21]
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

If MnSO4 → Mno+ SO3 is not a synthesis reaction, then what type of reaction is it?
9966 [12]
<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.
