Which elements have high densities, strength, and resistance to corrosion?
Advocard [28]

Answer:

transition elements

Explanation:

Metalloids are elements that have properties intermediate between those of metals and nonmetals. They are sometimes referred to as semi-metals. These materials have recently found great application in materials science and information technology.

Transition elements are however renowned for high densities and tensile strength. The transition elements have the highest density of all the element groups in the periodic table and also have resistance to corrosion. Transition metals such as gold silver and lead are coinage metals because they are resistant to corrosion.

Alkali and alkaline earth metals tarnish easily due to their high reactivity. They are usually very soft metals.

How many moles of O2 are required<br> if 12 moles of CuFeS are consumed?
MaRussiya [10]

Answer:

24 moles of oxygen are required.

Explanation:

Given data:

Number of moles of CuFeS = 12 mol

Number of moles of O₂ react = ?

Solution:

Chemical equation:

2CuFeS + 4O₂       →       Cu₂S + 3SO₂ + 2FeO

now we will compare the moles of O₂ and CuFeS.

                         CuFeS       :        O₂

                              2            :         4

                             12            :         4/2×12 = 24 mol
