Answer:

The average atomic mass is 86.565

Explanation:

An element's average atomic mass is the sum of the products of the masses of the isotopes of the element and their percentage abundance divided by 100

The average atomic mass of the Element X is given as follows;

Isotope type 1 (85.91) ×

Isotope ${}$ Abundance (%) Mass /100 Portion of average mass

Type 1 ${}$ 67.25 × 85.91 ÷ 100 57.774475

Type 2 ${}$ 32.75 × 87.91 ÷ 100 28.790525

${}$ Average atomic mass = 86.565

The average atomic mass = 86.565.

Use the periodic table and example bond table to answer the question.

lyudmila [28]

In keeping with the general trends, K-Br will have the smallest bond energy. The bond energy refers to the energy that keeps the atoms in a bond together.

<h3>What is bond energy?</h3>

Bond energy is the energy that is required to hold atoms together in a bond. This energy must also be supplied when the atoms are to be separated.

We have the bond energies of each of the bons in the question, we have to note that the the smallest value of bond energy is Na-Br hence in keeping with the general trends, K-Br will have the smallest bond energy.

A 100-watt light bulb radiates energy at a rate of 100 J/s. (The watt, a unit of power or energy over time, is defined as 1 J/s

Maslowich

Answer:

Approximately $2.64\times 10^{20}$ (assumption: wavelength $525\; \rm nm$ is measured in vacuum, where the speed of light is approximately $3.0\times 10^{8}\; \rm m \cdot s^{-1}$ .)

Explanation:

Convert the unit of wavelength to meters:

$\displaystyle \lambda = 525\; \rm nm = 525 \; \rm nm\times \frac{10^{-9}\; \rm m}{1\; \rm nm} = 5.25 \times 10^{-7}\; \rm m$ .

Assume that the wavelength $525\; \rm nm$ is measured in vacuum, where the speed of light is approximately $2.99792\times 10^{8}\; \rm m \cdot s^{-1}$ . Calculate the frequency of this light from its wavelength:

$\displaystyle f = \frac{c}{\lambda} \approx \frac{2.99792\times 10^{8}\; \rm m \cdot s^{-1}}{5.25 \times 10^{-7}\; \rm m} \approx 5.71429\times 10^{14}\; \rm s^{-1}$ .

The Planck's Constant can help find the energy of a photon given its frequency. Look up this constant to more than three significant figures:

$h \approx 6.62607\times 10^{-34}\; \rm J \cdot s^{-1}$ .

Calculate the energy of one such photon:

$\begin{aligned} E &= h \cdot f\\ &\approx 6.62607\times 10^{-34}\; \rm J \cdot s^{-1} \times 5.71023\times 10^{14}\; \rm s \\ &\approx 3.78370\times 10^{-19}\; \rm J \end{aligned}$ .

Calculate the number of these photons that $100\; \rm J$ of energy can produce under the assumption of $100\%$ conversion:

$\displaystyle \frac{100\; \rm J}{3.78370\times 10^{-19}\; \rm J} \approx 2.64\times 10^{20}$ .

(Rounded to three significant figures.)
