You're just supposed to write down what colors you see
The reaction is shown below,
Step 1: Hydration of Alkene: In first step
Ethene is hydrated to Ethanol through
Hydroboration Reaction.
Step 2: Oxidation of Primary Alcohol: In this step partial oxidation of ethanol is carried out using mild Oxidizing agent <span>Pyridinium chlorochromate (
PCC) and Acetaldehyde is produced.
Step 3: Reduction of Acetaldehyde followed by Oxidation: In this step, first acetaldehyde is reduced to
secondary alcohol using
grignard reagent. After that the sec. alcohol is oxidized to
ketone by using oxidizing agent CrO</span>₃.
Convert amount of molecules into moles using Avogadro’s number
9.40 x 10^25 molecules H2 x 1 mole / 6.02 x 10^23 molecules
= 156 moles H2
Convert moles of H2 into grams using H2’s molar mass (1.01 x 2 = 2.02)
156 mol H2 x 2.02 g / 1 mol
= 315 g H2
(1,2 because c is already on the other side so you have to reverse it
Answer:
Hi Lovelys!!
Answer down below!!
Explanation:
Answer: Plants need water for photosynthesis in order to make food. Water is needed more for cooling, to maintain body temperature and transport nutrients.
Reason: Plants need water for photosynthesis. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Too much water can cause a plant's roots to rot. Plants are about 80-95% water and need water for multiple reasons as they grow including for photosynthesis, for cooling, and to transport minerals and nutrients from the soil and into the plant.
Hope this helps!! =3
Have a wonderful day, evening, or night!!
