What are the special characteristics of chromium, iron , titanium and manganese

The two most useful properties of titanium include its resistance to corrosion and its high strength-to-weight ratio.

Chromium metal is highly valuable due to its high corrosion resistance and hardness.

Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
