Question

plss answer me this is physics​

Answer 1

Answer:7.

I) REACTANTS -

CaO : Calcium oxide

H2O : Water

CO2 : Carbon dioxide

AgNO3 : Silver Nitrate

NaCl : Sodium chloride

PRODUCTS-

C6H12O6 : Glucose

AgCl : Silver chloride

NaNO3 : Sodium Nitrate

O2 : Oxygen

Ca(OH)2 : Calcium hydroxide

ii) CaO + H2O = Ca(OH)2

AgNO3 + NaCl = AgCl + NaNO3

iii) C6H12O6 : 6×12+1×12+6×16 = 180u

iv) Ca(OH)2 is a precipitate in the reaction....

CaO + H2O = Ca(OH)2

Sorry friend but I don't know the answer of que. 8...

Please mark me as brainliest.....

BUT this is a question of "CHEMISTRY"....

Answer 2

7. a) Mix a colourless solution of silver nitrate with a colour less solution of sodium chloride. We will observe that colour less sodium nitrate with white precipitate silver chloride are formed.

AgNO3+NaCl➡NaNO3+AgCl (ppt.)

b) (i) calcium oxide,water, carbon dioxide,silver nitrate,sodium chloride.

(ii) AgNO3+NaCl➡NaNO3+AgCl (ppt.)

CaO+H2O➡Ca(OH)2

(iii) H2O

(iv) AgCl is a precipitate AgNO3+NaCl➡NaNO3+AgCl (ppt.)
