Give the stoichiometric coefficient for oxygen when the following equation is balanced using the lowest, whole-number coefficients. CH4O(l) + O2(g) → CO2(g) + H2O(l)

The stoichiometric coefficient for oxygen when the equation is balanced using the lowest whole number coefficients is 3

From the question,

We are to determine the stoichiometric coefficient for oxygen when the given equation is balanced.

The given equation is

CH₄O(l) + O₂(g) → CO₂(g) + H₂O(l)

The balanced equation using the lowest whole number coefficients is

2CH₄O(l) + 3O₂(g) → 2CO₂(g) + 4H₂O(l)

Hence, the stoichiometric coefficient for oxygen when the equation is balanced using the lowest whole number coefficients is 3

The coefficient for oxygen when the equation is balanced using the lowest, whole-number coefficients is 3.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced equation for the given reaction is;

The coefficient for oxygen when the equation is balanced using the lowest, whole-number coefficients is 3.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
