Answer:

3. both of the above

Explanation:

Living things interact with each other. Suppose you have a pond. It is an ecosystem. The fish in the pond interact with each other, and may even interact with other species like frogs or insect by eating them or living peacefully with them. Living things also interact with their environment such as fishes or some organisms might interact with the plants, logs, the available sunlight, all sorts of these factors which make up the environment.

Thus organisms within an ecosystem interact with each other and their environment.

A certain element has only two naturally occurring isotopes: one with 18 neutrons and the other with 20 neutrons. The element fo
melamori03 [73]

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.

Write two balanced equations
yanalaym [24]

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.
