I believe the answer is D. An ion always has a positive or a negative charge. An Ion is an atom with net electric charge due to the loss or gain of one or more electrons. An isotope is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their neutron, thus they differ in relative atomic mass but not in chemical properties.
To find the percentage yield you must take the actual yield and divide it by the theoretical yield and times it by 100. (Percent yield=Actual/Theoretical * 100)
For this example the calculated (Theoretical value) was 4.8 tones and the tones produced (Actual value) was 3.2 tones.
So 3.2/4.8 *100 = 66.6666666….

oh wait i wrote whole paragraphs let me fix this
okay so you mean this ?
a term for disaccharides would be double sugar or boise!
monosaccharides are simple sugars soluble in water. any class of sugars like glucose.
polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.
saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)

Answer:
New Gas volume (V2) = 5.86 L
Explanation:
Given:
Gas volume (V1) = 2.93 L
Temperature (T1) = 20°Celsius
After Increasing temperature:
New Temperature (T2) = 40°Celsius
Find:
New Gas volume (V2) = ?
Computation:
According to Charles' gas Law:
⇒ Gas volume (V1) / Temperature (T1) = New Gas volume (V2) / New Temperature (T2)
⇒ 2.93 L / 20°Celsius = New Gas volume (V2) / 40°Celsius
⇒ New Gas volume (V2) = 5.86 L
