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
Answers
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
Answers
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

Answers
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.

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
Answers
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%
