Answer:
[Cl-18]⁻ & [Cl-20]⁻
Explanation:
By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure. Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.
Answer:
its a
Explanation:
because a mutation is a change and a change can be a mutation
Answer:
1. NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat
2. NaOH + HCl → NaCl + H₂O
Explanation:
1. The dissolving of NaOH in water is an exothermic reaction resulting a heat. It also causes the dissociation of NaOH to its ions (Na⁺ and OH⁻).
So, the balanced equation will be NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat.
2. The reaction between acid and base resulting salt and water. It is considered as a neutralization reaction.
The reaction between HCl and NaOH will give sodium chloride and water and the balanced equation will be NaOH + HCl → NaCl + H₂O.
<span>I'd chose D. In all five years of the study, the control resulted in the least soil erosion as well as substantially less water loss compared to the two treatment situations. </span>
