Assertion :The characteristic of algal chloroplast are pyrenoids. Reason: Hornworts have pyrenoids.
Assertion: Be and Al have similar properties.
Reason: Be2+ and Al3+ have nearly the same charge/volume ratios and similar polarising power.
Assertion – The non-fusible impurities present in iron ore are removed by CaCO3 .
Reason: CaCO3 which decomposes into CaO and CO2. The CaO formed reacts with SiO2 to remove silica
