Chemistry

Slav-nsk [51]3 years ago

Answer:

Explanation:

so u can work out the amount of moles in FeO3 by doing mr of fe3o3 is 55.8*3+16*3=215.4

moles= mass/mr so you do 15.5g/215.4=0.0719 moles

then using 1 to 1 ratio so O2 moles is 0.0719

then use the equation mass=mole*mr

so 0.0719*16=1.15g

hope this make sense :)

Gelneren [198K]

Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

  • Halogens have a seven electrons in their outermost shell.
  • To complete the number of electrons in this shell, they need to gain an additional electron.
  • One more electron makes the halogen similar to the corresponding noble gas which is very stable.
  • Halogens are very reactive groups of elements and are highly electronegative.
  • They have a high affinity for electrons.
  • These elements are fluorine, chlorine, bromine, iodine and Astatine.
