Explain how elements are arranged on the periodic table. What does the table tell you when you read it like sentences in a book
DochEvi [55]

Explanation:

In periodic table:

  • Elements are arranged according to their atomic number in increasing order.
  • When we move left to right we move along a period.The period in the periodic table tell us about the principal quantum number,(n).
  • When move from top to bottom we are moving in group. The group in the periodic table tell us about the number of the valence electrons present in the valence shell of the elements of the particular group.

How many moles of sulfur trioxide are formed from 3 moles of oxygen using the given
fiasKO [112]

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.

How to calculate moles
blondinia [14]

Explanation:

First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.

For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
