Answer:
The student
identifies various ways
in which substances
differ (e.g., mass, volume, shape, density,
texture, and reaction
to temperature and
light).
Explanation:
It is an open circuit because the metal does not complete the electric flow
Answer 1 : The balanced complete ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Answer 2 : The balanced net ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Answer 3 : The balanced net ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Balanced equations : Balanced equations are the equations in which the number of individual elements present on the reactant side must be equal to the number of individual elements present on the product side.
Spectator ions : It is defined as the ions which do not participate in the chemical reaction. These ions exists in the same form on both the sides of the reaction.
Sulfur is a group six element in period 3 with atomic number 16 and an electronic configuration of 2:8:6. Therefore, to attain a stable configuration it requires to gain two electrons forming an ion with a charge of -2. The negative charge is due to the gaining of electrons.
