For the following chemical reaction, if 40.0 grams of o2 are completely reacted, how many grams of co2 will be produced? c2h4 + 3 o2 --> 2 co2 + 2 h2o

Hey there!:

Molar mass:

O2 = 31.99 g/mol   ;   CO2 = 44.01 g/mol

Given the reaction:

C2H4 + 3 O2 --> 2 CO2 + 2 H2O

3 * 31.99 g O2 2 * 44.01 g  CO2

40.0 g O2 mass of CO2 ??

mass of CO2 = 40.0 * 2 * 44.01 / 3 * 31.99

mass of CO2 = 3520.8 / 95.97

mass of CO2 = 36.68 g

Hope that helps!

here's the link to your question!

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.
