Answer:
Preparation of Bases
By the direct union of a metal with oxygen Some metals when heated in air or oxygen form the oxides of the metals. ... By the action of water or steam on some active metals Some active metals like sodium and potassium react with cold water to form hydroxides with the evolution of hydrogen gas.

Explanation:
The number of atoms of each element found in one unit of
the compound:
Potassium iodide,
KI, one atom K, one atom I
Sodium sulfide, Na2S, two atoms Na, 1 atom S
Silicon Dioxide, SiO2, one atom Si, two atoms O
Carbonic acid, H2CO3, two atoms H, 3 atoms O
The number of atoms that are present in 24g Carbon sample is
<h3>What is atom?</h3>
An atom can be regarded as the basic building block of chemistry and it is the smallest unit.
The Relative Molecular Mass of Carbon is known to be (12 g)
The Mass of the item was given as 24 g
Then we can find the Moles as ( 24g Carbon sample/24 g) = 2
Then the Number of atoms can be calculated as the
( Avogadro Number*Moles)
Therefore, the number of atoms that are present in 24g Carbon sample is 12.044*10^23
