Answer:
The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth. All of these elements are nonmetals.
Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
Answer:
Can either be a solid, a liquid or a gas
Explanation:
A solvent can either be a solid, liquid or a gas. It is the carrier medium in a solution. It is the one in which the solute is dissolved.
Although quite unusual, a solvent might also be a solid. An important application of this can be seen in the production of alloys. Alloys are mixture of metals. To produce let’s say an alloy containing just two metals, the use of a solid solvent is needed. Here, one of the two metals is known as the base metal. It is this base metal that will serve as the carrier medium for the other metal
27g of Aluminium
Explanation:
For Zachary tasked with obtaining one mole of aluminium, weighing 27g of the compound gives 1 mole of the element.
A mole is a simple unit of quantifying particles of a substance.
It is the amount of substance that contains the avogadro's number of particles.
The molar mass of a substance is the mass in gram of one mole of a substance.
The molar mass of Aluminium is 27g/mol
This is implies 1 mole aluminium has a mass of 27g.
Mass = number of moles x molar mass = 1 mole x 27g/mole = 27g
