Bohr's itself included that electrons take on energy equal to the energy required to the transition from one level to the other excited level.so if a very large amount of energy is given to the electron it will go in the exccited state <span>& if in case the amount of energy is too high..it will fly away from the atom.So A is the correct option</span>

Answer:

The correct answer is option D, that is, move up to another shell that would form.

Explanation:

An atom comprises neutrons, protons, and electrons. The neutrons and protons are located in the nucleus and the electrons orbit the nucleus in their fixed shells. The jumping of the electron takes place to its higher shell when it acquires some form of energy, and can move to the lower shell when it loses some energy. Therefore, as mentioned in the given question, when a single electron gains a small amount of energy, then it should jump to another higher shell.

What is the molarity of a solution containing 8.0 moles of solute in 120mL of solution?
Nataliya [291]
Answer:
200/3 M which is approximately equal to 66.6667 M

Explanation:
Molarity is defined as the number of moles of solute per liter of solution.

It can be calculated as follows:
molarity =  \frac{number of moles of solute}{liters of solution}

We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = \frac{8}{0.12} =  \frac{200}{3} = 66.6667 M

Hope this helps :)

Which of the following is a balanced equation?<br><br>Select one:<br>a. A<br>b. B<br>c. C<br>d. D​
Phantasy [73]

Answer:

B

Explanation:

Balanced equations have the same number of elements on both sides. If the number of elements are equal to each other for every element in the equation on both sides, then the equation is balanced.

Important concept : The big number before an element or compound represents how many molecules of that compound or element there are in a reaction. To find the number of atoms of each element you multiply the coefficient by the subscript ( small number ) which represents the number of atoms of that element in each molecule. Ex. 3H2O. There is a coefficient of 3 meaning that there are 3 molecules of H2O. There is a subscript after H meaning there are 2 atoms of hydrogen in each molecule. To find the total number of atoms we multiply the subscript of hydrogen by the coefficient of the whole molecule. 3 * 2 = 6 , so there are a total of 6 atoms of hydrogen in 3H2O

A) Cu + 2AgNO3 ==> CuNO3 + 2Ag

                    1   Cu  1

                    2   Ag  2

                     2   N  1

                     3  O   3

The amount of nitrogen atoms is different on both sides of the equation therefore this is not a balanced equation

B) CCl4 + O2 ==> CO2 + 2Cl2

                     1  C  1

                     4  Cl  4

                     2  O  2

The number of atoms of each element is the same on both sides of the equation therefore this is the balanced equation, however lets check the other answer choices just in case.

C)  2K + H2SO4 ==> K2SO4 + 2H2

                        2  K   2

                        1   H   4

                        1   S    1

                        4  O   4

The number of Hydrogen atoms are different on each side of the equation therefore this is not a balanced equation.

D) 2Al2O3 ==> 2Al + 3O2

              4  Al  2

              6  O  6
There are a different amount of aluminum atoms on both sides of the equation therefore this is not a balanced equation.

How do trends in the periodic table help predict the properties of an element
irina1246 [14]
As you move around there is a change in: electronegativies, ionisation energies, atomic radius etc. different amounts of these properties are going to effect how the element acts
