Explanation:
Answer:
The moon's surface has been struck with other objects.
Explanation:
Answer 1 - Craters are not a sign of alien life as there is nothing directly showing the crater's are not natural phenomena.
Answer 2 - Craters are (normally) produced by the impact force of a foreign object that is moving quickly and collides with an object of larger size.
Answer 3 - Volcanos form mountains and magma tubes, not craters.
Answer 4 - The formation of mountains does not relate to craters in any meaningful way.
Answer:
Because the entire body functions off of the air given to the body through the lungs.
This is due to the hydroxyl group in the alcohol which is able to form hydrogen bonds with water molecules.
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)
