Concept explainers
Interpretation: The special property of the Noble gases which makes them unreactive needs to be explained and also the reason of increase of boiling points and melting points of the Noble gas from He to Xe needs to be explained.
Concept Introduction:
In the Long form of periodic table, the non-metals are mainly placed at the right side of the periodic table that is called as p-block elements.
Metals make the 75 % part of the periodic table. Metals are electropositive elements and mainly form ionic compound, whereas non-metals are electronegative elements and can form either covalent or ionic compounds.
Noble gases are the elements which are placed in the group-0 of the periodic table at the right most side of the main body of the periodic table.

- Write a balanced chemical equation based on the following description: the reaction of gaseous tricarbon octahydride with oxygen gas produces gaseous carbon dioxide and water vaporarrow_forwardThe naturally occurring precursor to other strontium compounds [strontium carbonate] is produced by a precipitation reaction. Write an equation in which strontium carbonate is produced from strontium nitrate and potassium carbonate.arrow_forwardWhat are Nitrogen Oxides?arrow_forward
- What are the structural and molecular formulas for carbon dioxide?arrow_forwardWhich type of compound is used to color glass? O Alloys O Polymers O Metal oxides O Bases O Acidsarrow_forwardIf you blow carbon dioxide gas into a solution of calcium hydroxide, a milky-white precipitate of calcium carbonate forms. Write a balanced equation for the formation of calcium carbonate in this reaction. Calcium oxide is prepared by heating limestone (cal- cium carbonate, CaCO3) to a high temperature, at which point it decomposes to calcium oxide and carbon dioxide. Write a balanced equation for this preparation of calcium oxide. . The brilliant white light in some firework displays is produced by burning magnesium in air. The magnesium reacts with oxygen in the air to form magnesium oxide. Write a balanced equation for this reaction. Answer true or false. (a) Formula weight is the mass of a compound expressed in grams. (b) 1 atomic mass unit (amu) is equal to 1 gram (g). (c) The formula weight of H2O is 18 amu. (d) The molecular weight of H2O is 18 amu. (e) The molecular weight of a covalent compound is the same as its formula weight.arrow_forward
