Answer:
Elements in same group have same chemical properties due to same number of valence electrons in valence shell.
Explanation:
Chemical properties are those properties which results in transforming the starting material to a entirely new substance with different chemical and physical properties. This transformation takes place after a chemical reaction. Hence, the chemical reactivity of some atoms is greater than the others and vice versa.
In periodic table it is found that the elements in the same group have almost same chemical behaviour. For example, elements of group 8 (or 18) are almost non reactive, while that of group 1 and group 7 are found very reactive and show same chemical behaviour like group 1 elements forms +1 ion while group 7 elements form -1 ions as the group 1 metals have single valence shell electron which upon losing allow the atom to attain stability and the halogen having 7 electrons in valence shell upon accepting one electron allow them to attain a octet of stability respectively.
Normal galixies support millions of stars that support billions of planets. quesars are more similar to black holes. quesars also have gravitational pull
The reaction would shift to the right (forward).
Balanced chemical reaction: Br2(g) + 2NO(g) ⇌ 2NOBr(g)
According to the Principle the position of equilibrium moves to counteract the change.
The equilibrium shift to the right, so more product (nitrosyl bromide) will be produced. If the product is removed, the reactants will react to produce that product and set equilibrium.
Concentration of the reactants (bromine gas and nitric oxide) is reducing, while concentration of product is increasing.
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.
Speed of direct and irreversible chemical reaction are equal

I believe the correct response would be A. The ions once dissolved in the solution are free to move
Answer:
the energy store in an object is called potential energy
the unit of measure is called a joule
Explanation:
potential is what they can do and a joule is they're potential in measurement.
