4 0

Answer: Option (a) is the correct answer.

Explanation:

J.J. Thomson is a renowned scientist who discovered the model of atom which is known as the plum pudding model.

Through this model Thomson stated that an atom consists of small particles. These small particles are positive and negative charges present inside an atom.

Whereas Democritus stated that an atom is indivisible and thus he proposed the indivisible atom model.

Ernest Rutherford discovered that an atom has lot of empty space and this space is nucleus. As he stated that positively charged particles are known as protons which are present inside a nucleus.

Rutherford's gold foil experiment discovered that an atom has nucleus in which most of the mass of an atom is concentrated.

Thus, we can conclude that the plum pudding model was proposed as a result of J. J. Thomson’s work.

What is the molarity of a HCl solution that
ipn [44]

Answer:

M = 1.04 M

Explanation:

Given data:

Molarity of solution = ?

Mass of HCl = 6.27 g

Volume of solution = 163 mL (163 mL× 1L /1000 mL = 0.163 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Number of moles of HCl:

Number of moles = mass/molar mass

Number of moles = 6.27 g / 36.5 g/mol

Number of moles = 0.17 mol

Molarity:

M = 0.17 mol/ 0.163 L

M = 1.04 M
