Is iron (Fe) an ion? Name examples of ions. ​

Chemistry
1 answer:
Rudik [331]3 years ago
5 0

Answer:

yes Iron consists of iron atoms. Like all other atoms these are made up of a nucleus and electrons. If an iron atom gains or loses electrons it will become an ion. ... Neither does it make sense to say "iron is an ion", iron atoms can be ions, or part of ions

Explanation:

Aluminum - Al 3+

Barium - Ba 2+

Bismuth - Bi 3+

Cadmium - Cd 2+

Calcium - Ca 2+

Cesium - Cs +

Chromium (III) - Cr 3+

Cobalt - Co 2+

Copper (I) - Cu +

Copper (II) - Cu 2+

Hydrogen - H +

Iron (II) - Fe 2+

Iron (III) - Fe 3+

Lead (II) - Pb 2+

Lithium - Li +

Magnesium - Mg 2+

Mercury (I) - Hg2 2+

Mercury (II) - Hg 2+

Nickel - Ni 2+

Potassium - K +

Rubidium - Rb +

Silver - Ag +

Sodium - Na +

Strontium - Sr 2+

Tin (II) - Sn 2+

Zinc - Zn 2+

2 SO2(g) + O2(g) 2 SO3(g) Assume that Kc = 0.0680 for the gas phase reaction above. Calculate the corresponding value of Kp for
son4ous [18]

Answer: The corresponding value of K_p for this reaction at 84.5°C is 0.00232

Explanation:

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)

Relation of with is given by the formula:

K_p=K_c(RT)^{\Delta ng}

where,

= equilibrium constant in terms of partial pressure = ?

K_c = equilibrium constant in terms of concentration = 0.0680

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature  =84.5^0C=(273+84.5)K=357.5K

\Delta n_g = change in number of moles of gas particles = n_{products}-n_{reactants}=2-3=-1

Putting values in above equation, we get:

K_p=0.0680\times (0.0821\times 357.5)^{-1}\\\\K_p=0.00232

Thus the corresponding value of K_p for this reaction at 84.5°C is 0.00232

Identify what the electron dot diagram tells you about bonding
Alex_Xolod [135]

The electron dot diagram tells us about how many electrons are being shared between atoms. Also, the number of valence electron to be shared corresponds to the group number the element belongs. Say for example H2O, hydrogen has one valence electron and oxygen has two valence electrons.
