Question

A metal reacts with a substance X to produce a gas Y that burns with a pop sound. X also reacts with a metal carbonate to produce a gas Z that turns lime water milky. When X reacts with the base Ca(OH)2 it forms the corresponding sulphate salt M. Identify X,Y, Z and M and write the corresponding chemical equations.

Answer 1

⇝ Question :-

Identify X,Y, Z and M and write the corresponding chemical equations.

when,

• A metal M reacts with a substance X to produce a gas Y that burns with a pop sound.

• X also reacts with a metal carbonate to produce a gas Z that turns lime water milky.

• When X reacts with the base Ca(OH)2 it forms the corresponding sulphate salt M.

⇝ Answers :-

• $\text X = \text H_2\text{SO}_4$

• $\text Y = \text H_2$

• $\text Z = \text{CO}_2$

• $\text M = \text{Ca}$

⇝ Chemical Equations :-

$\sf Ca\text{(M)} +H_2SO_4\text{(X)} \: \longrightarrow \: CaSO_4 + H_2\text{(Y)}$

$\sf H_2SO_4\text{(X)} + CaCO_3\: \longrightarrow \: CaSO_4 + H_2O+CO_2\text{(Z)}$

$\sf H_2SO_4\text{(X)} + Ca(OH)_2 \: \longrightarrow \: CaSO_4 + 2H_2O$

⇝ Explanation :-

• We know that Hydrogen gives pop up sound on burning therefore the gas Y should be Hydrogen (H₂.)

• We know that carbon dioxide turns Lime water milky therefore the gas Z should be Carbon dioxide (CO₂).

• We Know that when Metals react with acids produces Hydrogen therefore substance X should be an Acid.

• Given that when X reacts with Ca(OH)₂ it forms corresponding sulphate therefore the acid should be Sulfuric acid (H₂SO₄).

• As Given When H₂SO₄ reacts with Ca(OH)₂ it forms Metal Sulphate and in reactants the only metal is calcium (Ca) so in product the metal M will be calcium (Ca).

Answer 2

Answer:

$\huge \sf{\underbrace{\underline{Answer: -}}}$

Given :-

• A metal reacts with a substance X to produce a gas Y that burns with a pop sound .X also reacts with a metal carbonate to produce a gas Z that turns metal carbonate to produce water milky.When,
• X reacts with the base Ca(OH)2 it forms the corresponding the base of Ca (OH)2. It forms the corresponding sulphate salt M.

♧To find :-

• Identifying X, Y, Z and M and write the corresponding chemical equations.

♧Proof :-

• Lets first write the the answer for your question.

♧Answer :-

• $X= H2So4$
• $Y=H2$
• $Z= CO2$
• $M=Ca$.

♧Next we can write the chemical equations:-

1. Ca (M)+H2So4(X)=CaSo4+H2 (Y)
2. H2SO4 (X)+CaC03=CaSO4+H2O+CO2(Z).
3. H2SO4(X)+Ca (OH)2=CaSO4+2H2O.

♧Explanation :-

• Here one thing we should know that ,Hydrogen gives pop sound when it is burning.Hence , hence the gas Y should be here Hydrogen.
• And also carbon dioxide also turns lime water milky .Hence Z should be (CO 2)Carbon dioxide.
• And also we know metal reacts with acid to produces Hydrogen. So the X substance be acid .
• In the question given that the X reacts with Ca (OH)2 and going to form corresponding sulphate. Therefore, Acid will be H2SO4.
• And in question given that the H2SO4 reacts with Ca (OH)2 and going to form metal sulphate.and in the reactant side we can see the only metal is calcium. Therefore, in product side metal M will be Ca.

♧Hope it helps u mate .
