Answer:
c. glycogen - is a polyssaccharide composed from sub-units of glucose
Explanation:
a. lactase - this is an enzyme compouse of many aminoacids and it has a complex structure
lactose - is a disaccharide composed from sub-units of galactose and glucose
b. glucose - is a monosaccharide
c. glycogen - is a polyssaccharide composed from sub-units of glucose
d. sucrose - a disaccharide composed from sub-units of glucose and fructose
e. triacylglycerol - is formed by condensation of glycerol with three molecules of fatty acids
Answer:
The concentration of chloride ion is 2.887 M.
Explanation:
Here we have a combination BaCl₂ and AlCl₃
1 mole BaCl₂ can produce 2 moles chloride ions as follows;
BaCl₂ → Ba²⁺ + 2Cl⁻
Therefore;
0.554 mole BaCl₂ can produce 2×0.554 moles chloride ions;
1 mole AlCl₃ can produce 3 moles chloride ions as follows;
AlCl₃ → Al³⁺ + 3Cl⁻
Therefore;
0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions
Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution
The concentration of Cl⁻ is 2.887 M
the correct answer would be mixture because compound uses the same element
Answer:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Explanation:
Answer:
NH3 Ammonia
Explanation:
Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
