Benzene (C6H6) is in gasoline. How many grams of carbon dioxide are produced by burning 400 grams of benzene? The unbalanced equation is: C6H6 + O2 → CO2 + H2O

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

50.23 i believe is correct but don't quote me on that.
