Why is drip irrigation more efficient? Drip irrigation is a very efficient way to irrigation crops and has the advantage of lower evaporation than other irrigation methods, it is the most common type of “microirrigation.” Drip irrigation is one of the more advanced techniques being used today because, for certain crops, it is much more […]

What happens when you add an inhibitor to a chemical reaction? A reaction inhibitor is a substance that decreases the rate of, or prevents, a chemical reaction. A catalyst, in contrast, is a substance that increases the rate of a chemical reaction. Does an inhibitor decreases the rate of a reaction? A (inhibitor) decreases the […]

How do you succeed in chemistry? How to Succeed in Chemistry Attend every lecture and don’t be late! College is a full-time job! Read, read, read… did I mention read? You cannot do enough practice problems! Chemistry studying should be active, not passive. Don’t be afraid to ask for help! When you do not understand […]

When solute dissolves into a solvent it is called? Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution. What is […]

Why are amino acids important to proteins? Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They’re needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters. What is an ionisable group? Functional groups that act as proton-donor […]

How is zinc carbonate prepared? The basic zinc carbonate is washed, dried, and milled. The method includes heating a solution made from urea with added zinc ash in a vessel from 90° C. to 150° C. to produce zinc-ammonia-carbonate complex and impurities dissolved in the solution and a residual. The solution is cemented with zinc […]

How does chemistry help cancer? The final tragedy of this neglect is that chemistry also provides the pathway to cancer prevention. By using natural compounds such as resveratrol and N-acetylcysteine to prevent the formation of estrogen-DNA adducts, the transformation of cells to malignancy is also prevented. How do chemists play a role in cancer research? […]

How does particle size affect viscosity? Decreasing particle size increases viscosity. The impact of increasing the number of particles present is magnified by these layers. This, in turn, increases the suspension viscosity by increasing the effective volume fraction for a specific particle loading. How does particle size affect flow rate? With the rise of particle […]

What is meant by dispersion in chemistry? Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. What is dispersed phase […]

Why does the word antibiotic suggest that these medications would be ineffective against viruses? Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria. Antibiotics work by targeting the growth machinery in bacteria (not viruses) to kill or inhibit those particular bacteria. What are antibiotics used to treat? […]
