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!

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
