In the following reaction, 451.4g of lead reacts with excess oxygen forming 356.7g of lead (ii) oxide. calculate the percent yield of the reaction. 2pb(s)+o2(g)= 2pbo(s)

The stoichoimetric ratio of lead to lead oxide is 2:2. Given 451.4 grams of lead, we get the moles multiply by 2/2 or 1 and the molar mass of lead oxide, we get a product of 486.26 g lead oxide. The percent yield is the actual amount, 356.7 grams over 486.26 grams which is equal to 73.36% yield.

What’s the question

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
