The answer for the following answer is mentioned below.
- Therefore the mass of calcium nitrate (
Explanation:
To find the mass of calcium nitrate ( ) is :
No of calcium are 1
No of nitrogen are 2
No of oxygen are 6
= 
So therefore;
No of nitrogen are 2
No of oxygen are 6
Mass of ( ) :
molecular mass of calcium =40
molecular mass of nitrogen = 14
molecular mass of oxygen = 16
= (14×2) + (16×6)
= 28 + 96
= 124
= 40 + 124
<u><em></em></u><u><em> = 164 grams</em></u>
Therefore the mass of calcium nitrate ( ) is 164 grams
Explanation:
From the image given;
Number of Protons = 1
Number of Electrons = 1
Number of Neutrons = 0
Positive Charge (From the protons) = + 1
Negative charge (From the electrons) = -1
Atomic mass = Mass of Proton + Mass of Neutron = 1.00727647 amu + 0.000549 amu = 1.00784 amu
Overall Charge = Positive charge + Neutral charge = 1 -1 = 0 (Neutral atom)
The number of moles of hydrogen atoms contained in 1 mole of c6h12 is 12.
<h3>What is hydrogen made of?</h3>
Hydrogen can be produced from various domestic resources such as fossil fuels, biomass, and the electrolysis of water by electricity. The environmental sustainability and energy efficiency of hydrogen depends on how hydrogen is produced.
Hydrogen is the simplest element. Each hydrogen atom has only one proton. Hydrogen is also the most abundant element in the universe. Stars like the Sun are mainly made of hydrogen. The sun is essentially a giant sphere of hydrogen and helium gas.
Some facts about hydrogen:
- Hydrogen is the most abundant element on earth.
- Hydrogen is an alternative fuel with a very high energy content by weight.
- The fuel cell can be used to power multiple applications.
- Fuel cells are a clean way to generate electricity.
Fuel cell vehicles are very similar to traditional gasoline vehicles

Explanation:
The chemical equation is as follows.
And, the given enthalpy is as follows.
; 
= 102.5 kJ
Cl-Cl = 243 kJ/mol, O=O = 498 kJ/mol
Since, the bond enthalpy of Cl-Cl is not given so at first, we will calculate the value of Cl-Cl as follows.
102.5 = ![[(\frac{1}{2})x + 498] - [(2)(243)]](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B1%7D%7B2%7D%29x%20%2B%20498%5D%20-%20%5B%282%29%28243%29%5D)
102.5 = 
102.5 - 12 = 
x = 181 kJ
Now, total bond enthalpy of per mole of ClO is calculated as follows.
x = ![[(\frac{1}{2})181 + (\frac{1}{2})498] - 243](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B1%7D%7B2%7D%29181%20%2B%20%28%5Cfrac%7B1%7D%7B2%7D%29498%5D%20-%20243)
= 339.5 - 243
= 96.5 kJ
Thus, we can conclude that the value for the enthalpy of formation per mole of ClO(g) is 96.5 kJ.
