Answer:
O3 is stronger oxidizing agent than HO2-.
Cl2 is stronger oxidizing agent than I2.
Zn^2+ is stronger oxidizing agent than Co^2+.
Br2 is stronger oxidizing agent than BrO3-.
Explanation:
An oxidizing agent oxidizes other compound by undergoing reduction itself.
Gaining of electron or hydrogen is reduction.
1. O3 is stronger oxidizing agent than HO2-. Because O3 readily gets decomposed into O2 and nascent (O), which oxidizes other compound. whereas as HO2- sometimes gets reduced to H2O2 and sometimes gets oxidized to O2.
2. Cl2 is stronger oxidizing agent than I2, as Cl2 can easily gain electrons compared to I2 due to its small atomic size.
3. Zn^2+ is stronger oxidizing agent than Co^2+, because Zn^2+ readily gains electrons compared toCo^2+ to form stable Zn due to its small atomic size.
4. Br2 is stronger oxidizing agent than BrO3-, as Br2 can accept electrons due to readily available empty orbitals compared to BrO3-.
Answer:
A higher concentration will increase rate of reaction because in a conc substance the particles are more clustered together and this causes more effective collisions thus increasing the rate of reaction.
Answer:
84.2mL
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 128mL
Initial pressure (P1) = 500mmHg
Final pressure (P2) = stp = 760mmHg
Final volume (V2) =..?
Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
500 x 128 = 760 x V2
Divide both side by 760
V2 = (500 x 128)/760
V2 = 84.2mL
Therefore, the new volume of the gas is 84.2mL
