Answer:
i guess it a right answer for you <em>✌</em>
Nonelectrolytes fail to ionize or dissociate in water becausethey are very strongly bonded to each other. Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. Hope this answers the question. Have a nice day.
4th one is the answer sorry if i am wrong i tried my best!
Answer:
Explanation:
The question states that the chemical equations should be balanced and the phases should also be indicated. The abbreviations of the phases have been indicated in the question with
i) (s) meaning the compound is in solid
ii) (aq) meaning the compound is in aqueous form
iii) (l) meaning the compound is in liquid
iv) (g) meaning the compound is in gaseous form
Balanced chemical equation is that in which the number of individual atoms on the reactant side is equivalent to the number of the same individual atoms on the product side.
Only the answer (the balanced chemical equations) will be written below.
A) This reaction is balanced
Mg(s) + Br₂(l) ⇒ MgBr₂(s)
B) P₄(s) + 5O₂(g) ⇒ P₄O₁₀ (s)
C) Ba(OH)₂(aq) + 2HNO₃(aq) ⇒ Ba(NO₃)₂(aq) + 2H₂O
D) Cr₂O₃(s) + 3C(s) ⇒ 2Cr(s) + 3CO(g)
The metals are found on the bottom left of the table, while the nonmetals are found at the top right. These elements are separated by a 'band' of semimetals
