The red diamond represents the potential hazards that are associated with the product.
Answer:The correct answer is option C.
Explanation:
At STP, 1 mol of gas occupies 22.4 L of volume
So, 100.0 L volume of 
will be occupied by :
According to reaction 2 moles are obtained from 1 mole of 
.
Then,4.4642 moles of will be obtained from :
that is 2.2321 moles of
Mass of gas:
Moles of gas Molar mass of gas:
Hence, the correct answer is option C.
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:
An ion has a positive or negative charge. While a covalent bond always has no charge, meaning it is neutral.
