The electron domain geometry of all of the above except XeF4 (answer E) is a tetrahedral.
Explanation
Tetrahedral is a molecular shape that result when they are four bonds and no lone pair around the central atom in the molecule.
The bond bonded to the central atom lie at the corner of tetrahedron with 109.5 degrees between them.
CBr4,PH3 , CCl2Br2 has a tetrahedral geometry while XeF4 has a square planar.
The limiting reagent : NH₃
<h3>Further explanation</h3>
A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactants become a limiting reactant
Reaction
4NH₃(g)+5O₂(g)⇒4NO(g)+6H₂O(g)
mol NH₃ :
mol O₂ :
mol ratio
NH₃ :
O₂ :
Limiting reactants : NH₃ (smaller ratio)
In the equation given above, the oxidizing agent is FeO.
An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide.
1.08 atm is the pressure for a certain tire in atmosphere.
<u>Explanation:</u>
One kilo pascal (1 kPa) corresponds to 1000 pascal. Another common unit used for pressure is atmosphere (symbolised as ‘atm’). 1 atm refers the standard atmospheric pressures and corresponds to 760 mm Hg and 101.3 kPa. Atmospheric pressures are commonly referred as square inches (psi)/ pounds.
Given:
The air pressure for a certain tire = 109 kPa
We need to find pressure in atmospheres
So, we know,
1 atm = 101.3 kPa
Hence,
1.08 atm is the pressure for a certain tire in atmosphere.
The energy that is lost from the generator becomes “unusable”. This energy was emitted as heat or mechanical energy, rather than electrical energy. Energy can never be destroyed, and it wouldn’t be considered lost if it was converted into the intended product.
