HVL is that amount of material that will reduce the original intensity to half of its value. One HVL will reduce the 100 R/minute to 50 R/minute, a second HVL will reduce the 50 R/minute to 25 R/minute

I have a buddy who recycles electronics, and isolates metals from the connector pins electrical boards. He isolates gold, for ex

Kisachek [45]

Answer:

Theoretical yield = 3.75g

Explanation:

Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:

Percent yield = Actual Yield / Theoretical Yield * 100

In the problem, your actual yield was 3-00g.

Percent yield is 80.0%.

Solving for theoretical yield:

80% = 3.00g / Theoretical yield * 100

Theoretical yield = 3.00g / 80.0% * 100

<h3>Theoretical yield = 3.75g</h3>

Experiments have shown that the equilibrium constant Kp for the reaction NO(g) + NO2(g) ⇌ N2O3(g) is 0.03. A chamber with a cons

zepelin [54]

Answer:

The reaction will shift to the right

Explanation:

In the reaction:

NO(g) + NO₂(g) ⇌ N₂O₃(g)

Kp of reaction is:

$kP = \frac{P_{N_2O_3} }{P_{NO}P_{NO_{2}}}$ = 0.03

Where P represents the pressures in equilibrium

Replacing in the kP formula the initial pressures:

$\frac{50MPa}{200MPa*250MPa}$ = 0.001

As the Reaction quotient (Q) is less than kP, the reaction will shift to the right producing more N₂O₃ until Q = kP.
