Question

which of the following statement(s) is/are true? (i) heating of limestone during cement production leads to the release of carbon dioxide. (ii) carbon dioxide is produced by burning carbon - containing compounds like wood, gas, oil, coal, and other carbon containing compounds. (iii) when water temperature rises in the ocean, the dissolved carbon dioxide in the ocean water is released into the atmosphere. statement i alone statements i and ii statement ii and iii statements i, ii, and iii

Explanation:

• Statement I: Limestone (CaCO₃) decomposes upon heating in cement - making, releasing CO₂.
• Statement II: Combustion of carbon - containing fuels like wood, gas, oil, and coal produces CO₂.
• Statement III: Solubility of CO₂ in water decreases with increasing temperature, so when ocean water warms, dissolved CO₂ is released to the atmosphere.

Answer:

Statements I, II, and III
