Classic light bulb running for a full year would use up 876 kWh of energy so yes it does collect energy
PH I think hope this helps
Answer:
d. End product is that product with a ketone and carboxylic acid.
Explanation:
Sodium borohydride is a reducing agent, it reduces the ketone to a primary alcohol.
Then acidified water is an oxidising mixture which reverses the reduction reaction.
Take a look at this and see if you can get an understanding and explain it in oxidation numbers
<h2>
Answer: x = 6</h2>
Explanation:
Molar mass of a compound is the sum of the molar mass of all the atoms of the compound.
⇒ Molar mass of the Nickel Compound (Hydrated Nickel (II) Nitrate)
= Molar mass (Ni+ 2N + 6O)+ x (2H+ O)
= [58.693 + 2(14.007) + 6(15.999)] + x [2(1.008) + 15.999] g/mol
= (182.701 + 18.015x) g/mol
Since the molar mass is known to be 290.7 g/mol
then 182.701 + 18.015x = 290.7
⇒ 18.015x = 290.7 - 182.701
x = (290.7 - 182.701) ÷ 18.015
∴ x = 6 [conventionally expressed as a whole number]
that makes the compound Nickel Nitrate Hexahydrate
