Aluminum bronze contains 92.0% copper and 8.0% aluminum. What maximum mass of aluminum bronze can be prepared from 73.5g of copp

er and 42.2g of aluminum? Initially I tried dividing 73.5g by 0.92, and I thought I have found the max mass of aluminum bronze. But then I tried using 70.0g of copper which gave me a result of about 82.17g of total mass of aluminum bronze. How should I calculate it accurately so that I can maximize the use of both metals?

The ratio of aluminum bronze components is:

92.0 Cu / 8.0 Al

The ratio of Cu and Al avilable is: 73.5 Cu / 42.2 Al

Then, it is evident that Al is in excess and Cu is the limitant material.

So, you need two work with the open proportion 92.0/ 8.0 = 73.5Cu / x

=> x = 73.5 * 8 / 92 = 6.39

Then, you can use 6.4 grams of Al and 73.5 grams of Cu to prepare 6.39g + 73.5g =  79.89.grams of Bronze.

I hope this helps.

What is the wavelength in nm of a light whose first order bright band forms a
miskamm [114]

Answer:

714 nm

Explanation:

Using the equation: nλ=d<em>sin</em>θ

where

n= order of maximum

λ= wavelength

d= distance between lines on diffraction grating

θ= angle

n is 1 because the problem states the light forms 1st order bright band

λ is unknown

d=  \frac{1}{700,000} or 0.0000014 (meters)

sin(30)= 0.5

so

(1)λ=(0.0000014)(0.5)

=0.000000714m or 714 nm
