Answer:
B) I2(s) is a stronger oxidizing agent than Al3 (aq), and Al(s) is a stronger reducing agent than I-(aq).
Explanation:
An oxidizing agent accepts electrons in a redox reaction and become reduced while a reducing agent looses electrons and become oxidized.
Hence in a redox reaction, oxidizing agents are reduced while reducing agents are oxidized.
Looking at I2 and Al3+, I2 is a better oxidizing agent since it has a reduction potential of +0.54V compared to -1.66V for Al3+.
Given the statements above, the converse must be true, that is; All is a better reducing agent compared to I-
Mass divided by Volume

The appropriate answer is c. It reduces pollution from runoff. Drip irrigation supplies water directly to the roots of the plants. This reduces loss of water from infiltration and evaporation. Water with nutrients is supplied directly to the roots of plants and so this reduces the chance of excess water infiltrating the soil and contaminating the ground water with pollutants.
Answer:
36.8 g/mol of O
Explanation:
To find the number of grams, multiply the number of moles by the atomic mass of the element.
Oxygen has an atomic mass of 16.00.
2.3 moles O × (16.00 g O ÷ 1 mole) = 36.8 g/mol O
