With strong heating, calcium carbonate undergoes thermal decomposition :CaCO³ (s) +CO²(G) (ci). What mass of calcium oxide is obtained from thermal decomposition of 50 g of calcium carbonate, assuming a 40% yield?
Answers
Answer:
a)CaCO 3→CaO+CO 2CaCO3→CaO+CO2
b) Moles of CaCO3=4.37moles
c) I) Mass of calcium oxide =28g
ii)Mass of carbon dioxide=16.7g
iii)Volume=203cm3
Explanation:
With strong heating, calcium carbonate undergoes
thermal decomposition:
CaCO3 (s) CaO (s) 1 CO2 ( g)
a Write a word equation for the change.
b How many moles of CaCO3 are in 50 g of calcium
carbonate? (Ar : Ca 5 40, C 5 12, O 5 16.)
c i What mass of calcium oxide is obtained from
the thermal decomposition of 50 g of calcium
carbonate, assuming a 40% yield ?
ii What mass of carbon dioxide will be given
off at the same time?
iii What volume will this gas occupy at rtp?

Explanation:
Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Wikipedia
