Answer:
% yield = 73.48 %
Explanation:
The fermentation reaction is:
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
The percent yield of C₂H₅OH is given by:
<em>where 
: is the obtained mass of C₂H₅OH = 67.7g and 
: is the theoretical mass of C₂H₅OH. </em>
The theoretical mass of C₂H₅OH is calculated knowing that 1 mol of C₆H₁₂O₆ produces 2 moles of C₂H₅OH:
<em>where M: is the molar mass of C₂H₅OH = 46.068 g/mol</em>
Hence, the percent yield of C₂H₅OH is:

Answer:
The mass of copper = 208.26 grams.
Explanation:
Density = mass / volume
8.9 = mass / 23.4
mass = 8.9 * 23.4
= 208.26 grams.
Answer:
cobalt (Co) is the correct answer.
Explanation:
The is most likely to bend without breaking element is cobalt because of the following properties.
- Cobalt is a ferromagnetic metal.
- Cobalt is a brittle and hard element.
- cobalt is not a nonmetal, it is a metal and metals are malleable and ductile means they can bend without breaking.
Hence Cobalt in their solid form they can be easily bent and changed into thin films without breaking
Answer:
Clouds form when air reaches its dew point, the temperature when the air is saturated. This can happen in two ways. First, the air temperature can stay the same while the humidity increases. This is common in locations that are warm and humid.

Explanation:
Answer: Genetics.
Explanation:
Genetics is a science that deals with the study of the inheritance of living beings and similarities. Genetics is responsible for the molecular function and structure of the gene. Genetics is responsible for inheriting the parental genes and passing them on to posterity. Genetics is an element that is also present in other living organisms. At its most basic level, inheritance in plants occurs via genes. The trait was first observed by Gregor Mendel, who explored the segregation of hereditary traits
