The combustion of 0.374 kg of methane in the presence of excess oxygen produces 0.983 kg of carbon dioxide. What is the percent
anyanavicka [17]
Assuming that the combustion formula is
CH4 + 2O2 --> 2H2O + CO2<span>,

That means for every 1 molecule of methane(CH4) there will be one molecule of carbon dioxide(</span>CO2) produced. Methane molecular weight 16, carbon dioxide molecular weight is 44. Then the percent yield should be:
1 * (0.374/ 16) /(0.983/44)= 0.374*44/ 0.983 * 16= 104.6%

You sure the number is correct? Percent yield should not exceed 100%

Which are abiotic factors?
son4ous [18]

Answer:

<h2>D. sunlight, climate, soil, water, and air</h2>

Explanation:

Did you know? An ecosystem is defined as any community of living and non-living things that work together. Ecosystems do not have clear boundaries, and it may be difficult to see where one ecosystem ends and another begins. In order to understand what makes each ecosystem unique, we need to look at the biotic and abiotic factors within them. Biotic factors are all of the living organisms within an ecosystem. These may be plants, animals, fungi, and any other living things. Abiotic factors are all of the non-living things in an ecosystem.

AgNO3 and NaOH were combined in the first reaction. If you were to use a scale to find the mass of the AgNO3 and the NaOH before
aliina [53]

<em>TLDR: They should be the same by the conservation law of masses. </em>

Now it may appear as if they changed if one of the resulting products is in the form of a gas or another hard to examine and weigh. In those situations it may seem that the masses will change, but the ratio should remain constant. <em>Try looking up 3.7: Conservation of Mass - There is No New Matter on ChemLibre for more information on this topic that goes more into depth about it. </em>
