1: methane burns in oxygen to yield carbon dioxide and water. the chemical formula for this reaction is ch4 + 2o2--> co2 + 2h2o. what is the product, or what are the products, of this reaction? .
a. oxygen and methane.
b. water and methane.
c. carbon dioxide and water.
d. carbon dioxide and methane

When   methane  burns in  oxygen  to yield carbon dioxide  and  water the products  of this reaction is  carbon  dioxide  and water (  answer C)

 Explanation

Product  is  substance  that is formed  as result of a chemical reaction.

 when   chemical reaction  is  written down   products are  written  on  right hand  side.

     Carbon  dioxide  and  water  are the product  since  are  yield of  the reaction when methane  burns in oxygen.  

In addition Carbon dioxide (CO2)  and water(H2O) are  written on  the right  side   when  writing down  the reaction of combustion of methane.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
