Answer:
Here, we are required to determine the total energy of the reaction and determine if the reaction is an endothermic or exothermic reaction.
The correct answer is option C.
First, we need to determine the energy of the reaction.
The energy of the reaction is the change in enthalpy between the product and reactants.
Change of Enthalpy,
Hreaction = Hproduct - Hreactant.
Therefore, for the reaction above, the change in enthalpy is:
Hreaction = 590kJ/mol - 581kJ/mol.
Hreaction = 9kJ/mol.
Hence, since the reaction has an enthalpy change of 9kJ/mol, the reaction is endothermic (i.e energy is absorbed).
Explanation:
The element found in the liver that helps prevent anemia is iron.
Iron is an essential element for blood production. Close to 70% of the body's iron is found in the red blood cells. In the red blood cells it is a vital ingredient of hemoglobin, the red pigment that gives blood its red color. In the muscle cells, iron is found as myoglobin.
Iron is stored mostly in the liver as ferritin or hemosiderin.
When iron stores are finished or exhausted, the condition is called iron depletion. When the shortage of iron is severe, it results in a condition known as iron deficiency anemia whereby the red blood cells do not have enough hemoglobin.
<h2>The required option d) "specific heat" is correct.</h2>
Explanation:
- To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
- Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
- It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
- Thus, the required "option d) specific heat" is correct.
