If 9.87g of As2O3 reacts with carbon, then 7.71g of As should be produced. If only 6.33g of As is actually produced, what is the percent yield of As?
a 82.1%
b 0.821%
c 64.1%
d 0.641 %
Answers
Answer:
A
Explanation:
Percent yield= Actual yield/Theoretical yield x 100
The problem tells you that 6.33g of As is produced (actual yield), but 7.71g should be produced (theoretical yield). So 6.33/7.71= 0.821 x 100= 82.1%

Explain the function of the nucleus, nucleolus, nuclear membrane, chromosomes, ribosomes, cytoplasm, cell membrane, mitochondria, Golgi complex, vacuole, endoplasmic reticulum, cell wall, chloroplast
Answers
nucleolus - producing and assembling the cells ribosome
nuclear membrane - separate the chromosomes from the rest of the cell
chromosomes - carries genetic information from one generation to another
ribosome - making proteins
cytoplasm - responsible for holding the components of the cell and protects them from damage, stores the molecules required for cellular processes and is also responsible for giving the cell its shape
cell membrane - provides protection for a cell, transport nutrients into the cell and also to transport toxic substances out of the cell
mitochondria - membrane-bound cell organelles that generate most of the chemical energy needed to power the cells biochemical reactions
Golgi complex - responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations
vacuole - (animal cells - help sequester waste products ) ( plant cells - help maintain water balance)
endoplasmic reticulum- produce proteins for the rest of the cell to function
cell wall - surrounds the plasma membrane of the plant cells and provides tensile strength and protection against mechanical and osmotic stress
chloroplast - allow plants to capture the energy of the sun in energy-rich molecules

48g of methane was burned in an excess of air. What mass of carbon dioxide would be produced in the reaction assuming complete combustion? Use the information below to answer the question.
Answers
Answer:
132g
Explanation:
CH4= 12+4=16
moles= m/Mr moles=48/16=3 mol
CO2= Mr=44
there are the same number of moles as methane:
Mass= Mrxmoles
44x3=132g
The mass of the carbon dioxide produced by the combustion of the 48 g of methane is equal to 132 g.
What is the combustion reaction?Combustion reaction involves the complete oxidation of the hydrocarbon such reactions generally release only carbon dioxide and water as products.
A hydrocarbon undergoes combustion to produce carbon dioxide and water as the product. No other side products are formed in the combustion reaction.
The given combustion reaction of the methane can be written as follows:
CH₄ + 2 O₂ → CO₂ + 2H₂O
Given the amount of methane for combustion = 48 g
The molar mass of methane = 16g/mol
The molar mass of the carbon dioxide, CO₂ = 44g/mol
16 grams of methane produce carbon dioxide = 44g
The 48 grams of methane will produce CO₂ = (44/16) ×48 = 132 g
Therefore, the mass of 132 g of carbon dioxide is produced by the combustion of 48g of methane.
