Answer: Cu3PO4

Explanation: Copper has an oxidation of Cu+1 and Phosphate a polyatomic ion is PO4 -3

Do the criss cross rule on their charges as the charge of Copper will be the subscript pf PO4 and vice versa.

koban [17]

Answer:

Yes

Explanation:

A supercritical fluid has good properties for both liquid and as for extraction properties, the advantages then include:

  • The fact that it has a lower viscosity than liquid CO2 allowing it to move through and around coffee beans more thoroughly with creating back pressure
  • Its density is comparable to that of liquid CO2 meaning there is much CO2 per litre as there is liquid form making it more efficient
  • It has a higher diffusivity than liquid CO2 which aids with penetration of the coffee beans on a molecular level

This experiment would not work with tea leaves because they also contain caffeine

A quantity of energy equal to 8.90 × 1012 joules was emitted from a nuclear reaction. What amount of mass was required to be con
Nataly [62]
E = mc^2
E = 8.90 * 10^12 Joules
c = 3 * 10^8 m/s
m = ????

8.90 * 10^12 = m * (3 * 10^8)^2
8.90 * 10^12 = m * 9 * 10^16
9.889 * 10^-4 kg = m <<<<< answer
