How many grams of methane, ch4 are produced from the complete reaction of 5.15 moles of carbon monoxide, co

 The grams  of CH4  that is  produced  is  82.4 grams

  calculation

 Co + 3 H₂  → H₂O + CH₄

Step 1  :  Use  the  mole ratio  to  calculate the  moles of CH4

   The    mole  ratio  of  Co:   CH4  is  1:1  therefore the  moles of   CH4  

    =  5.15  moles

step 2 :  use  the mass  of CH4

 mass  =  moles  x  molar mass

  molar mass  of CH4  = 12 +(1 x 4) = 16 g/mol

mass is therefore  =  5.15  moles x  16  g/mol= 82.4  grams

82.4

Explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
