Answer:
the radius is half the diameter
The correct answer is :
the purpose of heating the mixture is to accelerate the reaction and mix the reagent.
The explanation:
Many organic reactions are slow and can take an extended period of time to achieve any noticeable effect so heating is often used to increase the rate of reaction. However, many organic compounds have low boiling points and will vaporise upon exposure to such high heat, preventing the reaction from proceeding in full.
so, heating is used. This refers to heating a solution with an attached condenser to prevent reagents from escaping
Answer is 128.892 g.
moles (mol) = mass (g) / molar mass (g/mol)
According to the given data,
moles = 4.60 mol
mass = ?
molar mass = 28.02 g/mol
By substitution,
4.60 mol = mass / (28.02 g/mol)
mass = 4.60 mol x 28.02 g/mol
mass = 128.892 g
Hence, mass of 4.60 mol of N₂ is 128.892 g.
Answer:
The correct answer is b types of glycosidic bond between the monomers.
Explanation:
HomoPolysaccharides differ from each other by the presence of different glycosidic linkage within their chemical structure.
For example
1 Starch contain glucose residues which are linked by alpha-1,4-glycosidic linkage.
2 In glycogen molecule the glucose residues are linked together by both alpha-1,4-glycosidic linkage and alpha-1,6- glycosidic linkage.
3 In cellulose the glucose monomers are linked together by beta-1,4-glycosidic linkage.
Answer:
Yellow
Explanation:
Thymol blue has a brownish-green or reddish-brown color and is a good pH indicator. It changes from red to yellow at a pH 1.2–2.8 ( acidic) and then from yellow to blue at a pH of 8.0–9.6( alkaline).
Nitric acid is a strong acid which means the pH indicator will change to yellow.
