Answer: the weight of a object
Explanation:
Answer: Process B because it will reduce our dependency on fossil fuels.
Explanation:
Biofuels are the fuels which are produce by animals and plants matter. These fuels are generated by renewable sources like plants and animals which can be grown again for production of these fuels. These fuels limits our dependency on non-renewable fuels like coal, petrol and natural gas. Therefore, the non renewable fuels will remain available to fulfill the future generation needs. Hence, will help in conservation.
C. How long does it take a paper bag to break down?
Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
