Answer:
yes
Explanation:
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance
Answer: there must be 64 g + 24 g = 88 g of carbon dioxide present after the reaction.
Explanation: Since the total mass of substances used up in the reaction must be equal to the amount of product formed, according to the conservation of mass law,
4HCl + O₂ → 2Cl₂ + 2H₂O
mole ratio of HCl : O₂ is 4 : 1
∴ if moles of HCl = 2.3 mol
then mol of O₂ = 2.3 mol ÷ 4
= 0.575 mol
mass of O₂ = moles of O₂ × molar mass of O₂
= 0.575 mol × (16 × 2) g/mol
= 18.4 g
Answer:
When carbon dioxide is passed through lime water for a short time,it turns lime water milky due to formation of a white precipitate of calcium carbonate.
Explanation:
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
