Answer:
Radiocarbon dating can be used to determine the age of a sample less than 50,000 years old - C
20 g is the answer to make it a saturated solution
Answer:
D. The catalyst could absorb one of the particles, making a successful (reaction-producing) collision with the other particles more likely.
Explanation:
The way that a solid (heterogenous) catalysts functions is by the reactant getting adsorbed to the surface of the catalyst at active sites. An interaction between the surface of the catalyst and the reactant makes the reactants more reactive, causing the reaction to happen.
A.) Phosphate ion or Orthophosphate
d.) Hydroxide
D.) Ammonium
e.) Iron
C.) Nitrate
f.) Sulfur dioxide
No of moles of fe2o3 = 16.5/(55.8x2+16x3)=0.103mols
No. Of moles of iron= 0.103 x 2 = 0.206mols
Mass of iron = 0.206 x 55.8 = 11.5g
