Answers.......

Please bring in calculations......

Atesunate15: liver

You are correct. Reason is: its the phagocytes also know as scavenger cells in the liver that "eat" up dead red blood cells.

1: the pericardia is a very flat muscle which envelops the heart.
:2:don't know about 2
3:its d pancreas
4: reptiles and amphibians have a 3-chambered heart, mammals have 4 while fish have only 1 so the ansa is B.

Yes boss....

What volume of gas is involved at s.t.p if 2g of caco3 is added to a solution of HCl

a.224cm3
b.112cm3
c.240cm3
d.448cm3

If a solutn contains 4.9g of H2SO4, calculate d amount of cuo that will react with it

a.4.0g
b.8.0g
c.0.81g
d.40g

mayorall: What volume of gas is involved at s.t.p if 2g of caco3 is added to a solution of HCl

a.224cm3
b.112cm3
c.240cm3
d.448cm3

equation:CaCO3 + 2HCl -> CaCl2 + H2O + Co2
1 mole=22.4dm3
Caco3=1 mole
if 100g of caco3=22.4dm3
then 2g of caco3=x
x=22.4*2/100
x=44.8/100=0.448dm3
convert 0.448dm3 to cm3
;1 dm3 = 1000cm3
0.448dm3= xcm3
x=0.448*1000=448cm3
ans=D

mayorall: If a solutn contains 4.9g of H2SO4, calculate d amount of cuo that will react with it

a.4.0g
b.8.0g
c.0.81g
d.40g

equation:H2SO4 + CuO-> CuSO4 + H20
MOLAR MASS OF H2SO4=98g
MOLAR MASS OF CuO=79.5g
if 98g of H2SO4 will react with 79.5g of CuO
then 4.9g of H2SO4 will react with xg of CuO
THEN X=79.5*4.9/98
x=465.5/98=3.95
3.95 approx 4.
Ans=A
