Answer: Young engineers will learn how to problem solve, they will learn how to use creativity, and Critical thinking. STEM classes and robotics clubs help students become career engineers because it teach's things you will have to know to become a engineer in the future.
Idk look it up on another website
The term that is used to label the energy levels of electrons are principle quantum numbers and a valance band refers to the “energy levels in an atom where the electrons that participate in bonding occupy. These energy levels correspond to those of the s and p orbitals of the outermost shell of the atom being considered.” Hope this helps! :)
Answer:
Empirical formula is PNCl₂
Explanation:
Percent composition means that 100 g of compound has x g of each element.
In 100 g of compound x, we have 26.73 g of P, 12.09 g of N, 61.18 g of Cl.
So, let's make some rules of three:
In 100 g of compound we have 26.73 g of P, 12.09 g of N, 61.18 g of Cl
In 579.43 g of compound we have:
(579.43 . 26.73) / 100 = 155 g of P
(579.43 . 12.09) / 100 = 70 g of N
(579.43 . 61.18) / 100 = 354 g of Cl
Let's convert the mass of the elements in moles.
155 g of P / 30.97 g/mol = 5 P
70 g / 14 g/mol = 5 N
354 g / 35.45 g/mol = 10 Cl
