Answer : The electronic geometry and the molecular geometry of the molecule will be octahedral.
Explanation :
Formula used :
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is,
The number of electron pair are 6 that means the hybridization will be and the electronic geometry and the molecular geometry of the molecule will be octahedral.
Answer:
The chemical equation that is provided is :
4Fe(s) + 302(g) → 2Fe2O3(aq) + 1644.3 kJ
1. reactants :
In this equation, the reactants are iron or Fe and oxygen or O that react with one another to produce a new compound or product.
2. Products:
The single product is produced by the given equation after the reaction between Fe and O is Fe2O3 ferric or iron oxide.
3. states of matter (all)
Elements state
Fe solid
O gas
Fe2O3 aqueous
4. Coieficents (all)
Elements state
Fe 4
O 3
Fe2O3 2
5. subscripts:
Elements state
Fe single
O 2
Fe2O3 Fe = 2 and O = 3
6. yield :
The representation of yield is by the arrow between reactants and products that is: →
7. Exothermic or Endothermic:
The reaction generates the energy and gives it to the surrounding which confirms that the reaction is an exothermic reaction.
<u>Answer:</u> The mass percent of water in the hydrated sample is 21.5 %
<u>Explanation:</u>
To calculate the mass percentage of water in the hydrated sample, we use the equation:
We are given:
Mass of hydrated sample = 2.00 g
Mass of water = [2.000 - 1.570]g = 0.430 g
Putting values in above equation, we get:
Hence, the mass percent of water in the hydrated sample is 21.5 %
1.079*10^5 kilometers per hour
The energy released when a chemical compound reacts to produce new compounds is called Bonding Energy.
