Answer:
1.The reaction that opposes the change
Explanation:
Consider the reaction;
A + B ⇄ C + D
If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.
This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.
Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.
Answer:
The number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula
A compound is a substance that is a mixture of more than one elements.
Compounds are made of two or more elements. These elements are represented by their symbols. These symbols can be identified and the number of elements represented by these symbols are counted.
For example, in the compound H_2OH
2
O :
H represents Hydrogen
O represents Oxygen
The elements in Water ( H_2OH
2
O ) are Hydrogen and Oxygen
Therefore, the number of elements in H_2OH
2
O is 2
Also in, NaClNaCl
The elements are Sodium(Na) and Chlorine(Cl)
There are two elements in NaCl
Hence, the number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

In order to write the Aluminium electron configuration we first need to know the number of electrons for the Al atom (there are 13 electrons). When we write the configuration we'll put all 13 electrons in orbitals around the nucleus of the Aluminium atom.
