I’m assuming in this scenario that 2.5 mols of Fe2O3 is reacting with excess reactant. Based on the balanced equation, you can see that there’s a 1:2 ratio between Fe2O3 and Fe. This means that to find the mols of Fe formed, you need to multiply the mols of Fe2O3 by 2.
2.50mol Fe2O3 * 2mol Fe/1 mol of Fe2O3 = 5.00mols Fe.
Answer:
isolated system (plural isolated systems) (physics) A system that does not interact with its surroundings. Depending on context this may mean that its total energy and/or momentum stay constant.
Explanation:
An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. ... The system may be enclosed such that neither energy nor mass may enter or exit.
is there both?
Answer:
The answer should be, 0.01
Explanation:
0.01 = moles of NaOH
According to valence bond theory, atomic orbitals of slightly different mix and recast to form new orbitals of identical energies and properties. This process as called hybridization and, new generated orbitals are referred as hybridized orbitals.
Also, according to assumption of VBT, only central atom undergoes hybridization.
In case of HNO3, N is a central atom and it undergoes sp2 hybridization in HNO3. The structure of HNO3 is planner.
Further, HNO3 comprises of H+ and NO3- ion. Here, role of H+ is to act as counter ion and balance the charge on NO3-
Now, when HNO3 is mixed in water, it undergoes dissociation to generate H+ and NO3- ion. Here, parent ion i.e. NO3- is not disturbed. Hence, it's hybridization will not change. Only there will be minor variation in bond length and bond angle because of interaction of NO3- with H2O molecules.
