If a compound has a number of individual dipoles, then:

(i) it is polar overall.
(ii) there is an electronegativity difference between the bonded atoms.
(iii) it is ionic.
(iv) it doesn't have resonance.

(a) ii only
(b) ii, iv
(c) i, ii, iv
(d) i, iii
(e) all of the above statements are correct.

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

i dont know

explanation:

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
