Why does barium have a lower ionization energy than magnesium

Chemistry
1 answer:
Furkat [3]3 years ago
5 0

Answer:

Barium has a larger atomic radius because it has more energy levels and a larger shielding effect. Silicon has a smaller atomic radius because it has a stronger nuclear charge. ... Aluminum has a higher ionization energy than indium because there are fewer energy levels so it is more challenging to remove an electron.

when 6.25 grams of pure iron are allowed to react with oxygen , a black oxide forms. if the product weighs 8.15 g, what is the e
erik [133]
We are given with the mass of  pure iron that reacts with oxygen to form an oxide which has a given mass as well. the mass of oxygen reacted is 8.15-6.25 g or 1.9 grams. THen we convert the mass of the reactants to moles. Iron is equal to 0.1119 moles and oxygen is equal to 0.1188. We divide each number to the less amount. Hence iron is 1 and oxygen is approx 1. The empirical formula hence is FeO or ferrous oxide or Iron (II) oxide.

Answer:

A. 6.25moles

B. 0.78moles

C. 0.32moles

D. 0.15moles

E. 0.43moles

Explanation:

use

  • n = mass/molar mass

A. He

  • 25/4 = 6.25moles

B. O2

  • 25/32 = 0.78moles

C. Al(OH)3

  • 27+ 3(17) = 78
  • 25/78 = 0.32 moles

D. GaS3

  • 70+3(32) = 166
  • 25/166 = 0.15moles

E. C4H10

  • 4(12)+10(1) =58
  • 25/58 = 0.43moles
