In a reversible reaction, chemical equilibrium is attained when the (A) rate of the forward reaction is greater than the rate of

zepelin [54]

Answer: (D) concentration of the products remains constant.

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

Thus at chemical equilibrium, the amount of product and reactant remains constant because the rates of the forward and reverse reactions are equal.

A chemical equilibrium is dynamic in nature forward and backward reactions continue for indefinite time and never stops.

Chlorine (Cl) is in group 17. This element_____.

aleksklad [387]

Answer:

has 17 electrons

Explanation:

Chlorine is a halogen that belongs to the 17th group on the periodic table. Chlorine has an atomic number of 17. The atomic number of elements is used in placing and locating elements on the periodic table. In fact, the periodic arrangements of elements is as a result of their atomic numbers.

The atomic number is the number of protons in an atom. This number is the same as the number of electrons in a neutral atom that has not gained or lost any electron.

It is correct to say chlorine has 17 electrons and they occupy 3 electronic shells.

Calculate the mass of iron(III) oxide that contains a million iron atoms. Be sure your answer has a unit symbol if necessary, an

KiRa [710]

Answer: The mass of iron (II) oxide that contains a million iron atoms is $2.6\times 10^{-17}g$

Explanation:

We are given:

Number of iron atoms = A million = $1.0\times 10^6$

The chemical formula of the given compound is $Fe_2O_3$

It is formed by the combination of 2 iron atoms and 3 oxygen atoms.

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of particles

1 mole of iron (II) oxide will contain = $(2\times 6.022\times 10^{23})=1.2044\times 10^{24}$ number of iron atoms

We know that:

Molar mass of iron (II) oxide = 159.7 g/mol

Applying unitary method:

For $1.2044\times 10^{24}$ number of iron atoms, the mass of iron (II) oxide is 159.7 g

So, for $1.0\times 10^6$ number of iron atoms, the mass of iron (II) oxide will be $\frac{159.7}{1.2044\times 10^{24}}\times 1.0\times 10^6=2.6\times 10^{-17}g$

Hence, the mass of iron (II) oxide that contains a million iron atoms is $2.6\times 10^{-17}g$
