2.a
Explanation:
Photosynthesis is a useful reaction because it provides plants with food.... Rusting has disadvantages
Rusting is a slow process... complete combustion requires a lot of oxygen... photosynthesis requires carbon(IV) oxide and not oxygen
Answer:
Concentration of solution B is
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution,
where and are initial and final concentration respectively. and are initial and final volume respectively.
Here = , = 1.00 mL, = 10.00 mL
So, =
So, concentration of solution A =
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, =
So, concentration of solution B =
