Which statement is most consistent with the plum pudding model of the atom?

Chemistry
2 answers:
djyliett [7]3 years ago
7 0

Answer: 4) Negative particles are embedded in atoms


Explanation:


The plum pudding model of the atom depicts the atom as a solid sphere, positvely charged (pudding), and the negative charge, electrons (plums) uniformly distributed in the solid sphere (embedded in the pudding).


This is the electrons were distributed uniformly inside in a whole positive charge, just like plums in a pudding.


The scientist J.J. Thompson firts proposed this model to explain the neutral nature of the matter after the discovery of the electron.


Later, by 1911, the scientist Ernest Rutherforf, came out with the nuclear model of the atom as result of the gold foil experiment, which leat to think that the atom was mostly empty space (electrons surrounding a tiny nucleus).

The answer to this question would be: <span>1) Electrons occupy regions of space
</span><span>
In plum pudding model, the atoms are drawn as pudding and the negative particle is spread around the pudding. In this model, the electron is spread but not moving in orbit. Rutherford model that comes afterward is the one that says most of the atoms is empty space.</span>

Which of the following describes a scenario in which the molecular geometry would have the smallest bond angle(s)? (A) four bond
maw [93]

Answer: The correct answer is "B" two bonding domains(or bonding pairs) or two non bonding domains(or lone pairs)

Explanation:

Molecular geometry/structure is a three dimensional shape of a molecule. It is basically an arrangement of atoms in a molecule.It is determined by the central atom, its surrounding atoms and electron pairs.According to VSEPR theory, there are 5 basic shapes of a molecule: linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral.

A)Four bonding domains and zero non bonding domains: shape is tetrahedral and bond angle is 109.5°

B)Two bonding domains and two non bonding domains(lone pairs): shape is bent and bond angle is 104.5°

C)Three bonding domains and one non bonding domain: shape is trigonal pyramidal and bond angle is 107°

D)Two bonding domain and zero non bonding domain: shape is linear and bond angle is 107°

E)Two bonding domain and one non bonding domain: bent shape and bond angle is 120°

F)Three bonding domains and zero nonbonding domain: shape is trigonal planar and bond angle is 120°

Hence Two bonding domains and two non bonding domains have the smallest bond angle.

PLEASE<br> What is the H30+ concentration of a solution with a pH of 3?
Alenkinab [10]
PH = -log[H3O+]
Solving for [H3O+] gives
[H3O+] = 10^-pH
             = 10^-3 
or 1x10^-3 M

Object a has a mass of 12 G and a volume of 8 cm3 object be has a mass of 20 G and a volume of 8 cm3 which object has a greater
solniwko [45]

Answer:

Option C = object B by 1 gram per cubic cm.

Explanation:

Given data:

Mass of object A = 12 g

Volume of object A = 8 cm³

Mass of object B = 20 g

Volume of object B = 8 cm³

Densities = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Density of object A:

d = m/v

d = 12 g/ 8 cm³

d = 1.5 g/cm³

Density of object B:

d = m/v

d = 20 g/ 8 cm³

d = 2.5 g/cm³

object b has high density.
