Answer:
2I- ---> I2 + 2e- = O
Au+3 + 3e- ---> Au = R
Explanation:
The first loses electrons, so it is Oxidized, and the second one gains electrons, so it is Reduced. (Also I just did this and saw the answers were O and R respectively)
Answer:
i think option d
Explanation:

Liquid A
Explanation:
the least dense will be at the top. like icecubes in water. the ice is less dense than the water so it floats
Answer:
4383.28 g
Explanation:
First we'll need to <u>convert molecules into moles</u>, we can do so using <em>Avogadro's number</em>:
- 6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 moles
Then we will <u>convert 99.62 moles of carbon dioxide (CO₂) into grams</u>, using its <em>molar mass</em>:
- 99.62 moles CO₂ * 44 g/mol = 4383.28 g
