Answer:
D. It is a chemical reaction because the total mass remains the same when new substances are formed.
Explanation:
A chemical reaction is represented by a chemical equation which show the reactant and products. Reactants are written on left side of arrow while products are written on right side. The number of atoms are remain same however arrangement of atoms is different on both side.
For example:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen. The number of atoms are same on both side however arrangement of atoms is different.
While in case of nuclear reaction small change in mass take place.
Answer:
the answer is O²- hopefully
a balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
The correct answer to this is:
<span>Chondroitin sulfate is abundant in the matrix of <u>“Cartilage”.</u></span>
<span>A 1 unit of Chondroitin sulfate has a chemical formula of
C</span>13H21NO15<span>S. It is
usually found attached to proteins as part of a proteoglycan and is a vital
structure of cartilage by providing much resistance to compression. Due to
this, this chemical has found wide use as a dietary supplement for treatment of
osteoarthritis.</span>
