Calculate weight of CaO formed when 25 g of limestone isheated strongl

1.	Calculate weight of CaO formed when 25 g of limestone isheated strongly. Ca=40, C=12, O=16.(A) 1.4 g(B) 24 g(C) 14 g(D) None of theseAnswer with explanation will be marked as brainlist
Answer» ANSWER: Chemical REACTION involved is: CaCO 3 →CaO+CO 2 Molar mass of CaCO 3 =40+12+16×3=100 G According to the balanced reaction 100 g of CaCO 3 produces 1 MOL of CO 2 i.e. 22.4 L at STP. ∴50 g CaCO 3 will produce 100 22.4 ×50=11.2 L CO 2 at STP. Explanation: Mark it as brilliant

Answer»

Chemical REACTION involved is:

CaCO

→CaO+CO

Molar mass of CaCO

=40+12+16×3=100 G

According to the balanced reaction 100 g of CaCO

produces 1 MOL of CO

i.e. 22.4 L at STP.

∴50 g CaCO

will produce

100

22.4

×50=11.2 L CO

at STP.
