Reduce the amount of carbon, fossil fuels and methane in the atmosphere.
Answer:
- They are made of denser objects, which can condense at relatively high temperatures;
- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;
Answer:
Water is a covalent compound.
Explanation:
covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.
Example:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).
Properties:
1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.
2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
3. Covalent compounds have lower melting and boiling points.
Answer:
Photosynthesis is a physio-chemical process by which green plants use light energy to drive the synthesis of organic compounds. It is an enzyme regulated anabolic process.
