Consider the reaction 2 CO + O2 → 2 CO2 .What is the percent yield of carbon dioxide
(MW = 44 g/mol) if the reaction of 10 g of carbon monoxide (MW = 28 g/mol) with
excess O2 produces 8 g of carbon dioxide? Answer in units of %.

Thank u

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. the values of phosphorous acid are 1.30 6.70 calculate the ph for each of the given points in the titration of 50.0 ml of 1.5 m h3po3(aq) with 1.5 m koh(aq) .

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.
