<h3>
Answer:</h3>
498 kj/mol
<h3>
Explanation:</h3>
- Chemical reactions occur as a result of bond breaking and bond formation.
- The bonds in reactants are broken and atoms are rearranged to form new bonds.
- During bond breaking energy is absorbed to break the bonds of reactants while bond formation involves the release of energy during the formation of new bonds.
In our case;
In 1 mole of the Oxygen molecule, there is one O=O bond
Energy absorbed to break O=O is 498 kJ/mol
Therefore, the ΔH required to break all the bonds in one mole of Oxygen(O₂) molecules is 498kJ/mol.
Note that, bond breaking is endothermic since energy is absorbed from the surroundings.
Use Socratic for the answer hope it hlo elf
Hey, for #1, it's 1, 1, 1 because it's already balanced!
For #2, it's 1, 2, 1, 1 since the product side has 2 Cl's but left side only had 1.
<u>Answer:</u> The mass of iron found in the solution is 0.56 mg
<u>Explanation:</u>
ppm is the amount of solute (in milligrams) present in kilogram of a solvent. It is also known as parts-per million.
To calculate the ppm of oxygen in sea water, we use the equation:
Both the masses are in grams.
We are given:
Concentration of iron = 2 ppm
Mass of solution = 280 g
Putting values in above equation, we get:
<u>Conversion factor used:</u> 1 g = 1000 mg
Hence, the mass of iron found in the solution is 0.56 mg
