Answer:
Factories because they have helped with producing goods faster but in the meanwhile, our future will slowly get warmer.
Explanation:
Explanation:
Hybridization of 
is 
Bond pair in = 2
lone pair in = 2
Because of presence of two lone pairs of electron shape is bent.
F is more electronegative than O, therefore two O-F bons are polar and hence, two dipole exists. The resultant diople moment in a molecule is the vector sum of individual existing dipoles (shown in the attachment).
because of the bent shape of two dipole moments add to each other. this result in the existence of permanent dipole moment in the molecule and thus is a polar molecule.
Answer:
1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
Explanation:
This is the dissociation:
Ca(NO₃)₂ → Ca²⁺ + 2NO₃⁻
1.5 moles of salt will have the same moles of ion Ca²⁺ and the double of moles, of nitrate according to the equation.
Therefore will be 1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
If its a acid it will be 3 or if its a alkali then 14 or neutral then 7
