Which conversion factor do you use first to calculate the number of grams of CO 2 produced by the reaction of 50.6 g of CH 4 with O 2 ? The equation for the complete combustion of methane is: CH 4 ( g ) + 2O 2 ( g ) → CO 2 ( g ) + 2H 2 O( l )

The answer is c. 320 g

So3 that’s what i think

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
