Two atoms of potassium react with one molecule of chlorine to produce two molecules of potassium chloride. Option B

<h3>What is a chemical reaction equation?</h3>

The term chemical reaction equation has to do with the interaction between reactants and products. It deals with the process in which reactants are changed into products in a chemical reaction.

A word equation is an equation that uses words rather than the symbol of the elements that are involved. We are asked to write the equation 2 K(s) + Cl2(g) --- > 2 KCl(s) in words. The sentence that aptly captures the reaction as it is written is; two atoms of potassium react with one molecule of chlorine to produce two molecules of potassium chloride.

g The first step in the process is to calibrate the grating, so we know the grating spacing (the distance between the openings i
Trava [24]

Answer:

The grating spacing is  d = 1055nm

Explanation:

From the question we are told that

    The wavelength is  \lambda = 590 nm = 590 *10^{-9}m

    The angle is \theta = 34^0

    The  order of the spectrum is  n = 1

Generally in grating grating the condition for maxima   to occur is  

             d sin \theta  = n \lambda

where d is the grating spacing

     making d the subject of the formula

                  d = \frac{\lambda }{sin \theta }

        Substituting values

                  d = \frac{590 * 10^{-9}}{sin (34)}

                     d = 1055nm

Worth 40 Points❤ 10th grade chemistry ‍
brilliants [131]

Answer:

  1. F
  2. E
  3. G
  4. A
  5. C
  6. B
  7. D

Explanation:

Those are the answers in order, BUT the Goldstein and Rutherford ones are confusing me because Rutherford discovered<em> protons</em> and the <em>nuclear atom</em>. Through my research I also noticed that Goldstein contributed to the discovery of the protons made Rutherford, so I listed him as the one who discovered the proton.

I hope this helps! Have a wonderful night! :D

Which element among these has the most negative electron affinity (i.e., has most exothermic electron affinity). A. H B. Li C. C
OleMash [197]

Answer:

D. F

Explanation:

Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.

The electron affinity values of the following elements is given;

Electron Affinity of Hydrogen is 72.8 kJ/mol.

Electron Affinity of Lithium is 59.6 kJ/mol

electron affinity of carbon is 153.9 kJ mol‑1

Electron Affinity of Fluorine is 328 kJ/mol

The electron affinity of neon is 0 kJ mol‑1.

When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.

Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.

That explains why florine seems to have the highest electron affinity value.
