1. The forces make the train float because the poles are the same on each side causing them to repell (north and north repell)
2. B is more stable. If you pushed A it would fall and that would cause more disturbance
Answer: False
Explanation: just took on edge
Milli<span>- (symbol m) is a unit </span>prefix<span> in the metric system denoting a factor of one thousandth (10</span>−3<span>). Proposed in 1793 and adopted in 1795, </span>the prefix<span> comes from the Latin mille, </span>meaning<span> "one thousand" (the Latin plural is milia).</span>
Answer:
Reducing agents
Oxidized by the reaction
Sorry for late response on the answer.
Answer:
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
Explanation:
First, we will write the molecular equation, since it is easier to balance.
2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)
In the full ionic equation we include all ions and molecular species.
2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)
In the net ionic equation we include only the ions that participate in the reaction and the molecular species.
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
