I think it is C. coefficients but I don't know what subscripts are
The trend of electronegativity in the periodic table is increasing from left to right and from bottom to top. In the period 4 which is horizontal, the element which has the highest electronegativity is the right most element except the noble gas. This element is bromine.
Answer:
C₂H₆(g) + O₂(g) ⇒ CO₂(g) + H₂O(l)
Explanation:
Which of the following are combustion reactions?
NaNO₃(aq) ⇒ Na⁺(aq) + NO₃⁻(aq)
NO. This is a dissociation reaction.
C₂H₆(g) + O₂(g) ⇒ CO₂(g) + H₂O(l)
YES. This is a combustion reaction because a compound reacts with oxygen to form carbon dioxide and water.
Mg(s) + HCl (aq) ⇒ H₂(g) + MgCl₂(aq)
NO. This is a single displacement reaction.
HCl(aq) + NaOH (aq) ⇒ HOH(l) + NaCl(s)
NO. This is a neutralization reaction.
