Which of the following is NOT a correct ordering of subshells in the periodic table?

Igoryamba

3d < 4s is NOT a correct ordering of subshells in the periodic table because 4s is at a lower energy level than 3d.

According to the Aufbau principle, The electron configuration of an element tells how electrons of that element are arranged in thier subshells from their lowest energy state before the highest energy state.

For example, before a 2s subshell can be occupied, A 1s subshell must be filled.

The orbitals are filled in this order:

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s,

For example, Na (sodium) with 11 atomic number is written as 1s2 2s2 2p6 3s1

Therefore,

2p < 3s True

3d < 4p True

3d < 4s False

4s < 4p True

What is the (OH-) in a solution with a pOH of 6.48

inn [45]

Through manipulation of equations, we are able to obtain the equation:

$-pOH= log [ OH^{-}]$

Then we can transform the equation into:

$[ OH^{-}]= 10^{-pOH}$

Then we are able to plug in the pOH and directly get [OH-]:

$[ OH^{-}] = 10^{-6.48}$

$[ OH^{-}]=3.31* 10^{-7} M$

Given the unbalanced combustion equation: C3H8 + O2 → CO2 + H2O, how many moles of carbon dioxide are produced when 64.0 g of ox

gizmo_the_mogwai [7]

Moles of Carbon dioxide : 1.2

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction(balanced)

C₃H₈ + 5O₂=> 3CO₂ + 4H₂O

mol of O₂ :

$\tt \dfrac{64}{32}=2$

mol of CO₂ :

$\tt \dfrac{3}{5}\times 2=1.2$
