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

Keith_Richards [23]

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.

Explain why gases such as the oxygen found in tanks used as hospitals are compressed. why must care be taken to prevent compress

allochka39001 [22]

They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode. Before compressed oxygen can be breathed, it must be decompressed.

(b) The given number in 4 significant figures will be, $3.583\times 10^1$

(c) The given number in 3 significant figures will be, $2.24\times 10^1$

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

(a) The given number 00003554 converted into 2 significant figures.

In 00003554, there are 4 significant figures. Now we have to convert it into 2 significant figures.

The given number in 2 significant figures will be, $3.6\times 10^3$

(b) The given number 35.8348 converted into 4 significant figures.

In 35.8348, there are 6 significant figures. Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, $3.583\times 10^1$

(c) The given number 22.4555 converted into 3 significant figures.

In 22.4555, there are 6 significant figures. Now we have to convert it into 3 significant figures.

The given number in 3 significant figures will be, $2.24\times 10^1$
