A chemical process used to produce ethanol as a fuel additive was expected to produce 5,000 kilograms of ethanol based on the amounts of starting materials used, but only 4,760 kilograms were produced. What was the percent yield for ethanol in this process?
A)1.09
B)4.80
C)95.2
D)105
Answer:
C)95.2
Explanation:
Given parameters:
Expected yield = 5000kg
Experimental yield = 4760kg
Unknown:
Percentage yield = ?
Solution:
The percentage yield of the substance is determined by find the ratio of the true experimental yield to the expect yield and multiply by 100;
Percentage yield = [tex]\frac{4760}{5000}[/tex] x 100 = 95.2%

Which organelle of a prokaryotic cell contains genetic information?
cell membrane
ribosomes
nucleus
nucleoid
Answer:
The right option is the 4 one. nucleoid
Prokaryotic cells are simple cells that lack a definite nucleus and some membrane-bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm, and ribosomes.
Explanation:
Answer:
nucleoid

A boy sets up a picnic on the beach next to a sand dune. how are sand dunes formed?
Answer:
Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.
Classify the two balanced equations representing two chemical reactions
1 Cl2 + 2 NaBr + NaCl + 1 Br2 and 2 NaCl +2 Na + 1 Cl,
O Synthesis & Decomposition
O Synthesis & Double Replacement
O Single Replacement & Double Replacement
O Single Replacement & Decomposition
Single Replacement & Decomposition
Further explanationGiven
Two chemical reactions
1. Cl2 + 2NaBr ⇒2NaCl + Br2
2. 2NaCl ⇒2Na + Cl2
Required
Type of reaction
Solution
Equation 1 : A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Equation 2 : the decomposition reaction of a compound into its constituent elements or compounds
General formula :
AB ⇒ A + B
mole-mass problem:
Water decomposes to produce hydrogen gas and oxygen gas. How many moles of oxygen would be produced from 10.0 moles
water? 2 H2O → 2 H2 + O2
Answer:
5.00 mol O₂
Explanation:
2H₂O → 2H₂ + O₂In order to solve this problem we will need to convert moles of water to moles of oxygen. We will do that using the stoichiometric coefficients, as follows:
10.0 mol H₂O * [tex]\frac{1molO_2}{2molH_2O}[/tex] = 5.00 mol O₂Thus 5.00 moles of oxygen would be produced from 10.0 moles of water.

Calculate the molecular formula of a compound with the empirical formula CH O and a molar mass of 150 g/mol.
A) C2H4O2
B) C3H6O3
C) C4H8O4
D) C5H10O5
E) C6H12O6
The molecular formula : D) C₅H₁₀O₅
Further explanationGiven
The empirical formula CH₂O
The molar mass of 150 g/mol
Required
The molecular formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
(CH₂O)n = 150 g/mol
(12+2.1+16)n = 150
(30)n = 150
n = 5
