Question

F. By decomposition of 25 g of CaCO,,
the amount of Cao produced will be
a. 2.8 g
c. 14.0 g
b. 8.49
d. 28.0 g​
explain

Answer 1

Answer:

14g...

first right stricometric equation ....

caco3 = Cao + co2 ..

100 g 56 g 44 g

so now , 100 g = produce 56 g of Cao

then. 25 g = ? ..??..

then. .... 56 × 25 / 100 ..

= 14 ..

Hope this helps you.....

Pls mark me brainliest....

Answer 2

${\bold{\huge{\boxed {\mathcal {\red{SOLUTION:}}}}}}$

CaCO---->CaO+ CO2

68g 44g 56g

if 68g of CaCO will decompose to form 56g of CaO

then 25g of CaCO will decompose to form xg of CaO

so we get,

100g----> 56g

25g---->x g

$x = \frac{25 \times 56}{100} \\ x = 14.0g$
