Answer:
422455.41
Explanation:
Corrected from source,
Given that:-
The equilibrium constant for the reverse reaction will be the reciprocal of the initial reaction.
The value of equilibrium constant the reaction
is:
If the equation is multiplied by a factor of '3', the equilibrium constant of the reverse reaction will be the cube of the equilibrium constant of initial reaction.
The value of equilibrium constant the reaction
is:
Adding both the reactions we get the final reaction. So, the equilibrium constants must be multiplied.
The value of equilibrium constant the reaction
is:
= 422455.41
Answer:
Mg(OH)₂ + 2HCI → MgCI₂ + 2 H₂ O
Explanation:
Answer: The answers are:
The number of protons in an atom of an element is unique to each element.
A proton in an atom of one element is identical to a proton in an atom of another element.
Explanation: The number of protons in an atom of an element is unique to each element. The number of protons in an atom of an element is the atomic number of that element. Atomic number determines the chemical properties and reactivity of the atom.
All atoms are made up of three particles: protons, electrons and neutrons. These particles are identical in all the elements, what distinguishes one element from another is the number of each of these particles it contains. Therefore, a proton in an atom of one element is identical to a proton in an atom of another element likewise the electrons and neutrons.
Answer:
The physical and chemical properties of the product do not match the properties of the reactant.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg .
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
The reaction between sugar and oxygen form a product which is different from the reactant that's why it indicate the occurrence of chemical reaction.
While in case of physical changes just state of matter are changed. Properties remain same.
