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 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 is difference between FID and tcD detector?
What is difference between FID and tcD detector? the basic principle of FiD is the ionization of organic compound by burning the compounds in the hydrogen air flame. Meanwhile, the detection of compound by tcD is based on the difference of thermal conductivity properties between the carrier gas and the target being detected. What does […]
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 […]
