Ag2O + H2 --> 2Ag + H2O

Silver oxide is a very expensive reactant compared to hydrogen gas. If you were to carry out this reaction in the lab in the most cost effective way to produce a high yield, which of the reactants should be used in excess?

which is the charge that results when oxygen becomes an ion ?

1. The reaction Fecl3 + H20 (cold water)
i. Observation: what is the color of product formed and is it a solution, precipitate or a gelatinous precipitate.
ii. Inference: e.g is any ion present like fe3+, fe2+ etc
2. divide the result of the solution formed above into 2 portions (in 2 test tubes)
3. Take portion ONE and react it with dilute hcl
i. Observation : is there any color change or precipitate formed
ii. inference: What is the inference for the reaction i.e is any ion like fe3+ present or confirmed

1. Is the product formed from the reaction between iron iii chloride and water a solution or a precipitate.

the present of hydrogen bond in most molecules is responsible for
