Answer:

Refer to the periodic table to do this.

Explanation:

1. Na, K, Cs Fr, Rb

Sodium, Potassium, Cesium, Francium, Rubidium

3, 4, 6, 7, 5

Ascending order: Na, K, Rb, Cs, Fr

2. Ca, Sr, Ba, Ra, Mg

Calcium, Strontium, Barium, Radium, Magnesium

4, 5, 6, 7, 3

Ascending Order: Mg, Ca, Sr, Ba, Ra

When doing the electronic configuration of the elements, count how many number of divides it has. For example, Na(Sodium) has 11 electrons and it is divided like this: 2,8,1. So it divides into 3 parts so there will 3 shells for sodium.

Hopefully this helps!!

A chemist sets up a chemical reaction but finds that none of the reactant molecules have a required activation energy. What is t

Anvisha [2.4K]

Activation energy is the minimum amount of energy that the colliding reactant molecules must possess for the formation of products. Lower the activation energy, higher will be chance of formation of products. So activation energy is the minimum energy requirement that has to overcome for the reaction to be completed. Therefore, when in a chemical reaction the reactant molecules do not collide with required activation energy, the collisions will not be fruitful even if they are properly oriented which means that the products will not form.

Hence the correct answer will be B.) no products will be formed

Cu + 2H2SO4 ⟶ CuSO4 + SO2 + 2H20

In left hand side of the equation.

Cu = 1 atom

H = 4 atoms

S = 2 atoms

O = 8 atoms

In right hand side of the equation.

Cu = 1 atom

S = 2 atoms

0 = 8 atoms

H = 4 atoms

• All the atoms are balanced in the left and right side of the equation and it satisfies the law of conservation of mass.

• Equation is balanced and correct.
