It's a 50\50% but I am going to say true because of hydroelectric power

This is true because the water would have gravitational potential energy that is caused by the water being held back by the dam and the water wanting to flow down.

This can be converted into kinetic energy when given the chance to, such as having a turbine on the dam.

Hope this helps! :)

. Metallic iron has a body-centered cubic lattice with all atoms at lattice points and a unit cell whose edge length is 286.6 pm
adell [148]

Answer:

\large \boxed{\text{55.8 u}}

Explanation:

1. Calculate the volume of the unit cell

V = l³ = (2.866 × 10⁻⁸ cm)³ = 2.354 × 10⁻²³ cm³

2. Calculate the mass of a unit cell

\text{Mass} = 2.866 \times 10^{-23}\text{ cm}^{3} \times \dfrac{\text{7.87 g}}{\text{1 cm}^{3}} = 1.853 \times 10^{-22} \text{ g}

3. Calculate the mass of one atom

A body-centred unit cell contains two atoms.

\text{Mass of 1 atom} = \dfrac{1.853 \times 10^{-22} \text{ g}}{\text{2 atoms}} \times \dfrac{\text{1 u}}{1.661 \times 10^{-24}\text{ g}} = \textbf{55.8 u}\\\\\text{The molar mass of Fe from the Periodic Table is $\large \boxed{\textbf{55.845 g/mol}}$}
