<span>Answer:
If all atoms are to adhere to the octet rule, then only one structure is available. This would have S with a formal charge of +1 and all oxygens with formal charge of -1. A better structure would be for S to have a formal charge of 0, but it would then violate the octet rule. In that case however, there would be 3 resonance structures.</span>
To be honest, I can’t really see the question. So please next time just type it out lol
Answer:
1) Redox reaction
2) none of the above
3) none of the above
4) precipitation
5) acid-base neutralization
Explanation:
(1) Ba(ClO3)2(s)--->BaCl2(s) + 3O2(g)
In this reaction a single reactant produces (two or more)products which is a decomposition reaction.
But This is also a redox reaction, because Cl is reduced from
and Oxygen is oxidized . The answer is <u>redox.</u>
(2) 2NaCl(aq) + K2S(aq)--->Na2S(aq) + 2KCl(aq)
This reaction gives no insoluble precipitatwhich means, no reaction, despite the fact that it looks like a double replacement reaction. So the answer is <u>none of the above.</u>
(3) CaO(s) + CO2(g)--->CaCO3(s)
This is a synthesis (or combination) reaction where two or more reactants are formed out of 1 single product. <u>So none of the above.</u>
(4) KOH(aq) + AgCl(aq)---->KCl(aq) + AgOH(s)
This is a double decomposition reaction, also called a <u>precipitation</u> reaction, where two soluble salts react to form an insoluble salt and a soluble salt.
(5) Ba(OH)2(aq) + 2HNO2(aq)--->Ba(NO2)2(aq) + 2H2O(l)
An acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
This is a double replacement or <u>acid/base reaction.</u>
Answer:
Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. Water at its boiling point.
