Answer:

c) 4f1

Explanation:

Based on Aufbau principle electrons in an atom or ion fill up such that the orbital of the lowest energy gets occupied first followed by those with higher energy. The energy ordering of atomic orbitals is therefore:

1s>2s>2p>3s>3p>4s>3d>4p>5s>4d>5p>6s>4f.....

The integers 1,2,3 .. represent the principal quantum number 'n'

s,p,d,f are the atomic orbitals each of which can accommodate a maximum of 2, 6, 10 and 14 electrons respectively.

As per the energy ordering, the 4f orbital is highest in energy and hence the single electron present in the 4f orbital represented by the configuration 4f1 will have the highest energy.

In an exothermic reaction, the bonding energy of the product is:

ahrayia [7]

I think the correct answer from the choices listed above is option A. In an exothermic reaction, the bonding energy of the product is less than the reactant because it is only at this condition that the energy is released by the reaction.

1) A mixture of anhydrous sodium carbonate and sodium hydrogencarbonate of mass 10.000 g was heated until it reached a constant

vodomira [7]

The masses of the components are obtained as;

Sodium hydrogen carbonate = 3.51 g
Sodium carbonate = 8.708 g

<h3>What is decomposition?</h3>

The term decomposition has to do with the breakdown of the given substance into its components. The components of sodium hydrogen carbonate could be identified as water vapor, carbon dioxide gas and sodium carbonate. Among these products that have been listed here, we can see that it is only the sodium carbonate that remains as a solid. The others are gases that move away from the system that is under study.

Now putting down the equation of the reaction, we have;

$2NaHCO_{3} (s) ----- > Na_{2} CO_{3} (s) + CO_{2} (g) + H_{2} O(g)$

Now, the loss in mass must be due to the carbon dioxide and the water. Hence we obtain the loss in mass to be 10.000 g - 8.708 g = 1.292 g

Mass of sodium hydrogen carbonate = 2 * 88 g/mol * 1.292 g/62 g/mol

= 3.51 g
