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.

![\large \boxed{\text{0.25 kg}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Ctext%7B0.25%20kg%7D%7D)
Explanation:
We can use the formula for momentum to calculate the mass.
![\begin{array}{rcl}p & = & mv\\2 & = & m \times 8\\m & = & \dfrac{2}{8}\\\\& = & \textbf{0.25 kg}\\\end{array}\\\text{The mass of the ball is $\large \boxed{\textbf{0.25 kg}}$}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7Dp%20%26%20%3D%20%26%20mv%5C%5C2%20%26%20%3D%20%26%20m%20%5Ctimes%208%5C%5Cm%20%26%20%3D%20%26%20%5Cdfrac%7B2%7D%7B8%7D%5C%5C%5C%5C%26%20%3D%20%26%20%5Ctextbf%7B0.25%20kg%7D%5C%5C%5Cend%7Barray%7D%5C%5C%5Ctext%7BThe%20mass%20of%20the%20ball%20is%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B0.25%20kg%7D%7D%24%7D)
Total density of filled ball with hydrogen gas: ![\frac{0.12g+0.050344g}{0.560L} = 0.3041g/L](https://tex.z-dn.net/?f=%5Cfrac%7B0.12g%2B0.050344g%7D%7B0.560L%7D%20%3D%200.3041g%2FL)
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with hydrogen will float in the air because total density of filled ball is lessor than the density of an air.
Density of hydrogen gas = ![d_2 = 0.0899g/L](https://tex.z-dn.net/?f=d_2%20%3D%200.0899g%2FL)
Mass of the hydrogen gas : ![\frac{0.12g+0.050344}{0.560L} = 0.3041g/L](https://tex.z-dn.net/?f=%5Cfrac%7B0.12g%2B0.050344%7D%7B0.560L%7D%20%3D%200.3041g%2FL)

Explanation:if you’re not attending you don’t learn
Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.
The correct option is C.
Explanation:
Nitrogen gas has the chemical formula
, which means that two atoms of nitrogen element combined to form nitrogen gas.
The combination of two atoms of element nitrogen produce dinitrogen atom.
Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.
2 atoms of nitrogen element
N + N = ![N_{2}](https://tex.z-dn.net/?f=N_%7B2%7D)
the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
