Answer : The correct option is, 
Explanation :
The given element bromine belongs to the group 17 and period 4. The symbol of bromine is, Br.
The atomic number of bromine = 35
The total number of electrons present in bromine element = 35
Electronic configuration : It is defined as the arrangement of electrons around the nucleus of an atom.
Hence, the correct electronic configuration of bromine is,
Answer:
A balanced chemical equation explicitly provides you with the
a. conditions under which the reaction occurs.
b. molar masses of the reactants and products.
c. conversion factors needed to solve a stoichiometry problem.
d. mole ratios needed to solve a stoichiometry problem.
The correct answer to the question is
d. mole ratios needed to solve a stoichiometry problem.
Explanation:
A chemical reaction is sad to be balanced if it contains the complete list of reactants and products present in their relative proportions. The amounts of reactants and products can be calculated from a balanced chemical reaction equation by applying a process known as stoichiometry
An example of stoichiometry is the formation of two moles of water from one mole of oxygen and two moles of hydrogen
They all face the characteristics of life, they are all living, and they all have cells.
