Do we need oxidants? Oxidation can damage vital molecules in our cells, including DNA and proteins, which are responsible for many body processes. Molecules such as DNA are needed for cells to function properly, so if too many are damaged, the cell can malfunction or die. This is why antioxidants are important. Why are oxidants […]

Is radioactive decay bad?
Is radioactive decay bad? Radiation can either kill cells or damage the DNA within them, which damages their ability to reproduce and can eventually lead to cancer. When radiation is present, high energy particles pass through your body. These can collide with atoms in your body and disrupt atomic structure. What is a decay constant […]
What energies are involved in solution formation?
What energies are involved in solution formation? Energy is required for a solute to break its bonds. When you are forming a solution you need to break down the solute into its particles. The solute is the solid substance that you are dissolving. Bond breaking requires energy as the solute is relatively stable in its […]
What are the magnitude and direction of the electric field?
What are the magnitude and direction of the electric field? at point P, between both charges. Wanted : The magnitude of the electric field is zero located at…. Charge A is positive so that the direction of the electric field points away from charge A (to the right). Charge B is positive so that the […]
What will be the amount of work done to carry 4c of charge from a point at 100 V to a point 120?
What is the effect of HCl on the pH of water?
What is the effect of HCl on the pH of water? A molecule of hydrochloric acid, for example, is composed of a hydrogen atom and a chlorine atom. When these molecules dissolve into water, they separate into a positively charged hydrogen ion and a negatively charged chlorine ion. This leads to an increased concentration of […]
What happens to kinetic energy when velocity decreases?
What happens to kinetic energy when velocity decreases? Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased. Does kinetic energy increase velocity? It turns out that […]
