When designers require rugged, tough materials for their projects, steel and titanium are the first options that come to mind. These metals come in a wide assortment of alloys - base metals imbued with other metallic elements that produce a sum greater than its parts. There are dozens of titanium alloys and hundreds more steel alloys, so it can oftentimes be challenging to decide where to begin when considering these two metals. This article, through an examination of the physical, mechanical, and working properties of steel and titanium, can help designers choose which material is right for their job. Each metal will be briefly explored, and then a comparison of their differences will follow to show when to specify one over the other.

<u>Answer:</u> The mass of potassium superoxide required is 142.2 grams
<u>Explanation:</u>
The chemical equation for the reaction of potassium superoxide with water follows:

Number of moles of potassium superoxide reacted = 2 moles for given amount of heat released
To calculate the mass for given number of moles, we use the equation:

Molar mass of potassium superoxide = 71.1 g/mol
Moles of potassium superoxide = 2 moles
Putting values in above equation, we get:

Hence, the mass of potassium superoxide required is 142.2 grams
Answer:
the other number is different
