Which coefficient correctly balance the equation CaO + H2O -> Ca(OH)2
1 answer:
For the equation that we are given:
→
We see that on the reactants side we have:
Ca: 1 mol
O: 2 mol
H: 2 mol
And then we see that on the products side we have:
Ca: 1 mol
O: 2 mol
H: 2 mol
Therefore since we have equal moles of each of the elements on both sides of the equation, this equation is balanced how it is.
So the correct coefficients for this equation are: B) 1, 1, 1.

Answer:
Compound 1. Sulfur Dioxide
Compound 3. Dichloromethane
Compound 4. Phosphorus Trichloride
<em>(figure attached)</em>
Explanation:
Compound 1. Sulfur Dioxide
Polar compound
Through the Lewis structure it is confirmed that SO₂ is a polar compound, because it is an asymmetric compound having two regions of different polarity. The lower region having oxygen groups is more electronegative then the upper region.
Compound 2. Carbon Dioxide
Non polar Compound
Through the Lewis structure it is confirmed that CO₂ is a non polar compound, because it is a symmetric compound having two regions of same polarity. The left region and the right region both contains oxygen groups having same electronegativity.
Compound 3. Dichloromethane
Polar compound
Through the Lewis structure it is confirmed that CH₂Cl₂ is a polar compound, because it is an asymmetric compound having two regions of different polarity. Two chlorine atoms are attached to it and as we know that chlorine is a more electronegative element than hydrogen so it attracts the bonding pair of electrons towards itself which creates polarity.
Compound 4. Phosphorus Trichloride
Through the Lewis structure it is confirmed that PCl₃ is a polar compound, because three chlorine atoms attached to it and as we know that chlorine is a more electronegative element so it attracts the bonding pair of electrons towards itself which creates polarity.
