Answer:
The chemical composition of carbohydrates includes two oxygens and one hydrogen for every carbon present.
Explanation:
Generally, each carbon atom in the carbohydrates has one oxygen molecule and 1 – 3 hydrogen (depending on the position of the carbon in the chain and also the types of bonds around it). Usually, the ratio of hydrogen to oxygen in carbohydrates is approximately 2:1 Example of carbohydrates are starch and glycogen.
Answer:
Molecular formula = C₆H₁₂O₆
Explanation:
Given data:
Mass of hydrogen = 31.7 g
Mass of carbon = 283.4 g
Mass of oxygen = 377.4 g
Molar mass of compound = 176.124 g/mol
Molecular formula = ?
Solution:
Number of gram atoms of H = 31.7 / 1.01 = 31.4
Number of gram atoms of O = 377.4 / 16 = 23.6
Number of gram atoms of C = 283.4 / 12 = 23.6
Atomic ratio:
C : H : O
23.6/23.6 : 31.4/23.6 : 23.6/23.6
1 : 1.33 : 1
C : H : O =3 (1 : 1.33 : 1
)
Empirical formula is C₃H₄O₃.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 3×12+4+3×16 = 88
n = 176.124 / 88
n = 12
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₃H₄O₃)
Molecular formula = C₆H₁₂O₆
Answer:
Shampoo < corn syrup < honey
Explanation:
Shampoo flows fairly easily from the bottle, so would say it is the least viscous.
Both honey and corn syrup are quite viscous.
However, honey can range from liquid to solid at room temperature.
I have not seen solid corn syrup, so I would predict that it is less viscous than honey at a given temperature.
Answer:
b. erosion.
I believe that this is the best answer
