Answer:

9.77x10⁻³M HCl

Explanation:

<em>Assuming the solution of AgNO₃ is in excess:</em>

<em />

Based on the chemical equation:

AgNO₃ + HCl → AgCl + HNO₃

We must find the moles of AgCl that will be produced. With the moles and knowing 1 mole of AgCl is produced from 1 mole of HCl we can find the moles of HCl and its concentration as follows:

<em>Moles AgCl -Molar mass: 143.32g/mol-:</em>

0.7g AgCl * (1mol / 143.32g) = 4.88x10⁻³moles AgCl = Moles HCl

As the volume of the solution is 500cm³ = 0.500L, the concentration of HCl is:

4.88x10⁻³moles HCl / 0.500L =

<h3>9.77x10⁻³M HCl</h3>

What contribution did these scientists make to atomic models of the atom?
SashulF [63]

Answer:

Explanation:

Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.

In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.

The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons. Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.

777dan777 [17]

Answer:

1. K<10−3

Explanation:

Equilibrium Constant is an expression which involves the concentration of the product divided by the concentration of the reactant molecules.

However the concentration of the pure liquid and pure solid is regarded as 1.

Equilibrium expression for the equation 2H2(g)+O2(g)⇌2H2O(g)

Equilibrium Constant = [H2O]^2/[H2]^2 x [O2]

Since H2O is a pure liquid, its concentration = 1

There fore;

Equilibrium Constant = 1/[H2]^2 x [O2]

This shows that the Equilibrium Constant of the equation will be less than 1 and greater than 0.
