Answer:
The overall change in the oxidation number of sulfur is 8.
Explanation:
Oxidation number is defined number assigned to an element in reaction which represent the loss or gain of electrons by an atom of an element in a compound.
In
let the oxidation number of S in hydrogen sulfide be x.
x = -2
In
let the oxidation number of S in sulfate ion be x.
x = -2 + 8 = +6
The overall change in the oxidation number of sulfur :
= [+6] - [-2] = 8
Answer:
A: Both models represent atoms with the same atomic number.
Explanation:
The atomic number equals the number of protons.
Answer:
Collagen is a "fibrous proteins" present in the extracellular matrix.
Explanation:
Protein are made up of hundreds or thousands of smaller units called amino acids and is made of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and is found in many foods. Proteins are organic molecules found in living organisms.
There are three types of proteins; fibrous, globular, and membrane.
Collagen which is a fibrous proteins, form muscle fiber, tendons, connective tissue and bone.
Collagen are naturally occurring proteins that consist of single molecules made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. It is mostly found in fibrous tissues such as tendons, ligaments, and skin.
The synthesis of collagen occurs in two stages: intracellular and extracellular.
Collagen is an abundant connective tissues such as cartilage, tendons, bones, and ligaments. Collagen is a contributing factor to variation in meat tenderness and texture.
Answer:
=0.1293 J
Explanation:
The heat increase is the change in energy for the water ΔH.
ΔH=MC∅ where M is mass, C is the specific heat capacity for water and ∅ is the change in temperature.
M=0.7892g
C(for water) =4.2 J/g°C
∅=0.039 °C
ΔH=0.7892g×4.2 J/g°C×0.039°C
=0.1293 J
The amount of heat energy added to cause the 0.039°C temperature increase is 0.1293 Joules.
