Answer:
Exothermic
Explanation:
The energy is the ability to perform a job or to produce heat, and chemical reactions involve a rearrangement of atoms between substances with rupture or formation of chemical bonds.
Endothermic reactions are those that absorb energy in the form of heat.
On the other hand, an exothermic reaction is a way in which energy is released from the system into the environment.
Enthalpy (ΔH) represents the exchange of energy between a thermodynamic system and its surroundings. An endothermic reaction will always have a enthalpy variation (ΔH) greater than zero (ΔH> 0). An exothermic reaction will always have a enthalpy variation (ΔH) less than zero (ΔH< 0).
So in this case, the reaction is exothermic.
Answer:
Products are stearate anion and water.
Explanation:
Stearic acid is a 18-carbon chain molecule containing -COOH group. IUPAC name of stearic acid is octadecanoic acid.
Molecular formula of stearic acid is
.
When
is added into stearic acid,
removes a proton (
) from acidic -COOH group and forms stearate anion and water as products.
The balanced acid-base reaction is given as:

Structure of products are given below.
Answer:

Answer:
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
