Answer:
A) ψ² describes the probability of finding an electron in space.
Explanation:
The Austrian physicist Erwin Schrödinger formulated an equation that describes the behavior and energies of submicroscopic particles in general.
The Schrödinger equation i<u>ncorporates both particle behavior</u>, in terms of <u>mass m</u>, and wave behavior, in terms of a <u><em>wave function ψ</em></u>, which depends on the location in space of the system (such as an electron in an atom).
The probability of finding the electron in a certain region in space is proportional to the square of the wave function, ψ². According to wave theory, the intensity of light is proportional to the square of the amplitude of the wave, or ψ². <u>The most likely place to find a photon is</u> where the intensity is greatest, that is, <u>where the value of ψ² is greatest</u>. A similar argument associates ψ² with the likelihood of finding an electron in regions surrounding the nucleus.
The answer is A. Mom carefully bandaged my finger.
A change which would remove the source of this error is to: Test a fourth group, in which participants do not receive the mineral supplements.
<h3>What is a scientific method?</h3>
A scientific method can be defined as the various techniques that are adopted to observe, investigate, examine and study a particular thing while giving explanations on the basis of the evidence, theory, proof, hypothesis, or factual information they derived from the research work.
In this scenario, a claim was made by the company its mineral supplements can effectively prevent common cold. However, this claim was disputed by a scientist because there exist an error in the group setup.
<h3>How to remove an error in science</h3>
For this investigation, an effective and efficient way to remove this source of error would be by testing a fourth group, in which the mineral supplements is not administered to any of the participants.

Answer:
32. Opcion E
Explanation:
ZO₂ podemos entenderlo como dióxido de Z
1 mol de ZO₂ contiene 1 mol de Z y 2 moles de O₂ por lo que si la masa molar es de 64 g/mol, podemos plantear lo siguiente
Masa de Z + 2 masa de O = 64 g/mol
Sabemos que la masa del oxígeno es 16 g/mol
x + 2. 16 g/mol = 64 g/mol
x = 64 - 32 → 32 g/mol
La masa atómica coincide con la masa molar, por lo tanto la masa atomica de Z es 32.
Answer:
Exothermic
Explanation:
Exothermic reactions release heat, endothermic absorb heat, and precipitate is a solid formed from a solution
