The carbon atom is uniquely suited to building large molecules primarily because of its valence electron count of 4 - which means it can bound up to 4 atoms (single bonds) simultaneously. Also, it has a relatively low molecular weight and the best part is that it forms covalent
bonds (stable, high
energy bonds) with other, non-metallic atoms.
Answer:
Cows and other ruminant animals (like goats and sheep) emit methane, a potent greenhouse gas, as they digest grasses and plants. This process is called “enteric fermentation,” and it's the origin of cows' burps.
Explanation:
Answer:
The correct option of the first option
Explanation:
Dissolution of a solute in a solution is the process in which the solute interacts with the solvent leading to the disappearance of the solute to form a solution. Rate of dissolution is primarily affected by three factors namely
<u>Stirring of the solution</u>: Stirring the solution causes the solute to interact more with the solvent, <u>thus increasing the rate of dissolution</u>.
<u>Surface area of the solute</u>: The smaller the surface area of the solute, the more easier it is for it (the solute) to interact with the solvent. Hence, <u>the smaller the surface area, the faster the rate of dissolution</u>.
<u>Temperature of the solvent</u>: An increase in temperature of the solvent <u>causes the generally causes more things to dissolve in this solvent</u> due to increased energy of molecules in the solvent, which causes the molecules of the solute and solvent to interact more.
A decrease in the amount of solute<u> will reduce the amount of interaction the solute (since it is in lesser quantity) have with the solvent hence the rate of dissolution will also be low (even though a solution will still be formed)</u>.
