Identify the blocks and groups of elements in the periodic table​
djyliett [7]

Explanation:

The periodic table is a table that arranges elements based on their atomic numbers into groups and periods.

The groups are the vertical arrangement of elements. All elements in a group share similar chemical properties because they have the same number of elements in their valence shell. The periodic table groups are:

               Group                             Other names

              1A or 1                               Alkali metals

              IIA or 2                              Alkaline earth metals

             IIIA or 3                            Boron family

             VIA or 6                             Chalcogens

            VIIA or 17                            Halogens

             O-18                                  Inert elements

             IIIB-IIB                              Transition elements

There are 18 vertical columns divided into 8 tall groups or main groups which are 1A to O. The short groups or subgroups are from numerals 1B to VIII.

The periodic table can be divided into four blocks based on the type of sublevels their valence electrons occupy.

  • Group IA and IIA constitute the s-block
  • Group IIIA to O constitute the p-block
  • The transition elements makes up the d-block
  • The lanthanides and actinides makes up the f-block

What is the smallest particle representing water?
horrorfan [7]
Water is a compound that is made up of oxygen and hydrogen atoms, therefore the smallest particle of water is water molecule. The smallest particle representing water is written as H2O. H2O is the smallest unit to which water can be split while still retaining the properties of water.

A chemist added an excess of sodium sulfate to a solution of a soluble barium compound to precipitate all of the barium ions as
grigory [225]

Answer:

  259.497 mg,   58.84%

Explanation:

BaSO₄ → Ba²⁺ + SO₄²⁻

to calculate the mole of BaSO₄

mole BaSO₄ = mass given / molar mass = 403 mg / 233.38 g/mol = 1.7268 mol

comparing the mole ratio

1.7268 mol of BaSO₄ yields 1.7268 mol of Ba²⁺

403 mg BaSO₄  yields     ( 1.7268 × 137.327 ) where 137.327 is the molar mass of Barium mol of Ba²⁺

441 mg BaSO₄  will yield   ( 1.7268 × 137.327  × 441 mg ) / 403 mg = 259 .497 mg

mas percentage of the Barium compound = 259 .497 mg / 441 mg × 100 = 58.84%
