Mm h2o2 = 34.02 g/mol mm h2o = 18.02 g/mol mm o2 = 32 g/mol 2h2o2 —> 2h2o + o2 if 14.3 moles of h2o2 is decomposed, how many grams of oxygen has are produced? show all your work to get full credit. ( ! )

  The grams   of oxygen that  are   produced  is  228.8 grams

  calculation

2H₂O₂ → 2H₂O +O₂

Step 1:  use  the  mole ratio to determine the moles of O₂

from equation above H₂O₂:O₂  is   2:1

therefore the  moles of O₂  = 14.3 moles ×1/2 = 7.15   moles

Step 2:  find  mass   of O₂

mass = moles ×  molar mass

= 7.15 moles × 32 g/mol =228.8 g

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
