What is the maximum number of electrons found in any energy level of the known elements? (Refer to the periodic table.)

Answers

Answer 1
Answer:

Answer:

2n^2 electrons

Explanation:

for example, the first level contain 2*(1^2) = 2 electrons, the second level contain 2*(2^2) = 8 electrons, etc
Answer 2

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5m/s. What is the mass of the bowling ball

Answers

Hello!

Data:

F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

F =m*a

22 = m*5.5

5.5 m = 22

m = (22)/(5.5)

\boxed{\boxed{m = 4\:Kg}}\end{array}}\qquad\checkmark

I hope this helps. =)

What is the difference between relative humidity and humidity?

Answers

Relative humidity tells you how much water vapor is in the area. Humidity is like a ratio of absolute humidity and the potential amount of water saturation that may be in an area.

How many atoms and ions does lithium sulfite have?

Answers

Answer:

Hence the ions per mole are:

Li^(+)= 2 ions

SO_(3)^(2-)(aq)= 1 ions

In one mole of Li2SO3 , the number of the atoms are

N_(a)=6.022* 10^(23)

Explanation:

The formula of  lithium sulfite is Li2SO3.

Li_(2)SO_(3)

It contain Li+ and SO3(2-) ions.This can be represented by :

Li_(2)SO_(3)(s)\rightarrow 2Li^(+)(aq) +SO_(3)^(2-)(aq)

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the ions per mole are:

Li^(+)= 2 ions

SO_(3)^(2-)(aq)= 1 ions

Number of atoms in  lithium sulfite depends upon the mass of the Li2SO3 present .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.

N_(a)=6.022* 10^(23)

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

Number\ of\ Atoms=Moles* (N_(a))

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

Moles=(mass)/(Molar\ mass)
