Answer: Glucose is an example of carbon-based macromolecule known as carbohydrates
Explanation:
carbon based macromolecule are important cellular components and they perform a variety of functions necessary for growth and development of living organisms. There are 4 major types of carbon based molecules and these includes;
Carbohydrate
Lipids
Proteins and
Nucleic acids.
Carbon is the primary components of these macromolecules. Carbohydrate macromolecules are made up of monosaccharide, disaccharide and polysaccharides. Glucose is an example of a monosaccharide and it has two important types of functional groups: a carbonyl group and a hydroxyl group. I hope this helps. Thanks

Answer:
The change in entropy is -1.66 kJ/K.
Explanation:
Heat of vaporization of acetic acid = 41.0 kJ/mol
Heat of condensation of acetic acid = -41.0 kJ/mol
Mass of acetic acid = 954 g
Condensing temperature of acetic acid =118.1 °C = 391.25 K
Moles of acetic acid =
Heat evolved during condensation of 15.8867 moles of acetic acid:
Entropy change = ΔS =
The change in entropy is -1.66 kJ/K.
Answer:
Explanation:
Given that:
The heat of combustion of methylhydrazine =
It means that:
1 mole of methylhydrazine on combustion, releases of energy
Molar mass of methylhydrazine = 46.072 g/mol
Means that, 1 mole of methylhydrazine contains 46.072 g of methylhydrazine
Thus,
46.072 g of methylhydrazine on combustion, releases of energy
Also,
1 g of methylhydrazine on combustion, releases of energy
206.2 g of methylhydrazine on combustion, releases of energy
Heat released =
Answer: option C) Na, Mg, K
Explanation:
Similar chemical properties are expressed by elements found in the same or close groups. There are Seven (7) groups in the Periodic table.
Of all the options, ONLY sodium Na, Magnesium Mg, and Potassium K, are located in closely together with SODIUM and MAGNESIUM being in the Same period, while SODIUM and POTASSIUM are placed in the same Group 1.
Therefore, Na, My, and K are most similar in chemical properties
