Sodium is a metal that belongs to group 1 of the periodic table.
<h3>What is my favorite element?</h3>
My favorite element is sodium. Sodium is found in group one of the periodic table. The element is univalent and also forms univalent positive ions. Like every other metal, sodium is able to react with dilute acids to liberate hydrogen gas.
Sodium is a light metal and is known to react with mercury to form the sodium mercury amalgam which is obtained during the electrolysis of sodium chloride. All of the compounds that are formed by sodium are ionic in nature. However the hydrides of sodium are unstable.
Sodium is highly reactive thus it must not be exposed to air since it could ignite spontaneously in air. As such, sodium must be stored under paraffin oil. All the compounds of sodium are ionic in nature.

The balanced equation for the reaction between NaOH and HCl is
NaOH + HCl ---> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
during neutralisation, number of H⁺ ions = OH⁻ ions. Together they form water molecules and neutralise the solution as water is neutral.
Number of NaOH moles in 1000 ml - 0.2 mol
therefore in 12.5 ml -0.2/1000 x 12.5
= 0.0025 mol
at neutralisation point , number of OH⁻ mol = number of H⁺ ions
since stoichiometry of base to acid is 1:1
number of HCl moles reacted = 0.0025 mol
concentration is the number of moles in 1000 ml
in 25 ml number of HCl moles - 0.0025 mol
Therefore in 1000 ml - 0.0025 mol /25 x 1000
concentration of HCl - 0.1 M
Answer:
1.) KI
-------> potassium iodide
Potassium (K⁺) is a metal and iodine (I⁻) is a nonmetal. Therefore, when naming, there are no prefixes denoting how many of each element is in the compound. Because potassium is listed first in the compound, it must be the cation. Because iodine is listed second, it must be the anion. Anions in naming have their endings dropped and have the suffix -ide added.
2.) Fe₂O₃
-------> iron(III) oxide
Iron (Fe³⁺) is a metal and oxygen (O²⁻) is a nonmetal. Therefore, when naming, there are no prefixes denoting how many of each element is in the compound. Because iron is listed first, it is the cation and oxygen is the anion. Both of the elements have charges that do not balance each other (denoted by the subscripts). Because iron can have multiple different charges, the charge of iron (+3) should be listed when naming.
3.) (NH₄)₃PO₄
-------> ammonium phosphate
Ammonium (NH₄⁺) and phosphate (PO₄³⁻) are both polyatomic ions. When these ions bond, they also don't have quantity prefixes. Ammonium is the cation and phosphate is the anion. No roman numerals are necessary because the polyatomic ions always have a particular charge.
Answer:
Yes
Explanation:
Natural gas is colorless and odorless, and explosive, so a sulfur-smell (similar to rotten eggs) is usually added for early detection of leaks. ... Natural gas is a fossil fuel. Natural gas is a non-renewable hydrocarbon used as a source of energy for heating, cooking, and electricity generation.
