Answer:
The number of moles of salt in one tablespoon is = <u>0.11 mole</u>
<u>Grams </u>cancel each other.
Explanation:
<u>Moles</u> : It is the unit of quantity . It is the mass of the substance present in exactly 12g of C-12.

<u>Moles Calculation:</u>
Given mass = 6.37 gram
Molar mass = 58.5 g/mol

= 0.1088
= 0.11 mole
<u>Units calculation</u>



<u>g ang g cancels each other </u>
moles = moles
<u>Hence unit = gram (g ) cancel each other.</u>
Answer is: both reactions are exothermic.
<span>In exothermic reactions, heat is released and enthalpy of reaction is less than zero (as it show second chemical reaction).
According to Le Chatelier's principle when the reaction
is <span>exothermic heat is included as a
product (as it show first chemical reaction).</span></span>
For Iron:

For Oxygen:

These are the two chemical symbols for the two elements found in Iron Oxide.
