Answer:
181 picometers is the radius of a gallium atom.
Explanation:
Primitive cubic cell is an arrangement in which constituent particles are present only at the corners of the cube.Also known as simple unit cell. In this arrangement number of total particles is equal to 1.
![\frac{1}{8}\times 8 =1](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%5Ctimes%208%20%3D1)
Gallium crystallizes in a primitive cubic unit cell.
Edge length of cubic unit cell = a = 362 pm
Let the radius be gallium atom be r
Two atoms of gallium touching each other = a =2r
362 pm = 2r
r = 181 pm
181 picometers is the radius of a gallium atom.
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Converting from moles of one compound into moles of another compound in a chemical equation will require the " <u>stoichiometric factor</u>".
The balanced equation's coefficients serve as the foundation for stoichiometric factors, often known as mole ratios, that are employed to compare the moles of one product as well as a reactant to those of another.
A balanced chemical equation's stoichiometry determines the most product that could be produced. A reaction's stoichiometry specifies the proportions of reactants as well as products in a stable chemical equation.
Therefore, converting from moles of one compound into moles of another compound in a chemical equation will require the " <u>stoichiometric factor</u>".
