Answer:

15.0L

Explanation:

p/v = constan

(9*21)/253 =(15v)/ 302

v = (9*21*302)/(15*253)

v=15.0

Why does metal need to be extracted from an ore before it can be used?
Hunter-Best [27]
Metal ore has other elements in it as well. Also sediment and stone might cover the ore. We don't want to have a phone with sediment on it do we? thus these few reasons are why.

Silver is a precious metal. The price of silver fluctuates daily as it is traded on the open market. Look up the current market
Vlad [161]

Answer:

- Current market value of silver produced in the experiment = $0.2763

- Check Explanation for the appearance of leftover copper wire used in the experiment.

Explanation:

Price of Silver on today's market = $15.34 per troy ounce

Amount of Silver produced in the experiment = 0.56 g

31.1 g = 1 troy ounce

0.56 g = (0.56/31.1) = 0.01801 troy ounce

1 troy ounce = $15.34

0.01801 troy ounce = 0.01801 × $15.34 = $0.2763

The original reaction to extract the silver is one between Copper metal and the Silver Nitrate.

The Copper metal dissolves in the Silver Nitrate to give Copper Nitrate thereby displacing the Silver ion to become silver metal which we just valued above. But copper nitrate is a blue solution, So, it is a good estimate to say that the entire solution changed to that blue colour and the appearance of the leftover copper metal is colour blue. The silver metal forms as fractal-like crystals on this leftover copper.

Hope this Helps!!!

W7L5 Stoichiometry Practice 2
Rzqust [24]

Answer:

.079 moles of Nirogen gas (N2)

Explanation:

You can see from the equaton that each ONE mole of N2 produces TWO moles of NH3.

 Find the number of moles of NH3 produced.

    Using Periodic Table : Mole wt of NH3 = 17 gm/mole

          2.7 gm / 17 gm/mole = .1588 moles

      One half as many moles of N2 are needed  = .079 moles
