Answer:
Low melting point.
Explanation:
We cannot link the pH of a substance from it bonds directly.
Ionic compounds have strong ionic bonds but we cannot say that they will have high or low pH.
High conductivity is a feature of ionic compounds generally (also metals)
low melting point means the bonds are weak so they can be weak covalent bonds.
Low flammability is not related to bonding.
Labeled carbon and oxygen, coming from carbon dioxide as source
Plants are autotrophs, which means that they capable of producing their own "food" from inorganic substances using energy from light or chemical reactions. Plants produce their food mainly by photosynthesis, which utilizes energy in the form of sunlight to convert carbon dioxide in the atmosphere to complex organic molecules as source of food.
