Answer: The correct option is d.
Explanation: Antoine Lavoisier is a french scientist who discovered the role of oxygen in the process of combustion and respiration.
He was famous for the law of conservation of mass.
This law states that the total mass the reactant will equal to the total mass of the products in a chemical reaction.
For example: Combustion of methane
Mass of the reactants = ![[12+4(1)]+[2(32)]=80g/mol](https://tex.z-dn.net/?f=%5B12%2B4%281%29%5D%2B%5B2%2832%29%5D%3D80g%2Fmol)
Mass of the products = ![[12+2(16)]+2[2(1)+16]=80g/mol](https://tex.z-dn.net/?f=%5B12%2B2%2816%29%5D%2B2%5B2%281%29%2B16%5D%3D80g%2Fmol)
Hence, every chemical reaction will follow law of conservation of mass.
ANSWER
Heterogeneous mixture
EXPLANATION:
Given information
From the above image, we can see that we have three elements named a, b, and c. The elements a and c are attached to each other while element b can move freely.
Recall that, the combination of two or more elements is called a compound.
The above image shows the combination of a compound and an element
Hence, we can say that it is a heterogeneous mixture
If the number of electron is more than the protons,the atom is negative
if the number of electrons is less than the protons, the atom will be positive
Answer:
Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.
