Question

How many millilitres of ozone gas at 25°c and 1 atm pressure are needed to react with 45 ml of a 0.100 M aqueous solution of KI according to the following chemical reaction O3+2I-+h2o gives O2+I2+2OH-

Answer 1

Answer:lil

Explanation:

Answer 2

Answer:

hello dear

Explanation:

Step 1) get the moles of any substance with information provided (KI)

0.045L*0.100mols/L = 0.0045mol of KI which is equal to mols of I- as KI ->( K+) +( I-)

Step 2) get the moles of substance needed (03) use the formula

0.0045mols I- * (1mol of O3)/(2 mols I-) = 0.00225 mols O3
