Does oxygen form a positive or negative ion? Negative ions are called anions . Oxygen is in group 6. An oxygen atom has six electrons in its outer shell. The atom is more stable if it has a full outer shell….Forming negative ions. Atom name Ion name Sulfur Sulfide Which form of oxygen is the […]
Why does losing gaining an electron cause the other element to gain lose atoms?
Why does losing gaining an electron cause the other element to gain lose atoms? Answer: A positive ion is formed where an atom has more protons than electrons. Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to […]
What is Zn plus S?
What is Zn plus S? Names: Zinc sulfide , Zincblende , Wurtzite show more. Appearance: White-to-yellow crystals or powder. Is Zn a reactant? A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products. In the equation above, the zinc […]
What are the similarities and differences between kinetic and potential energy?
What are the similarities and differences between kinetic and potential energy? KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, […]
How do you treat multidrug resistant bacteria?
How do you treat multidrug resistant bacteria? Current Treatment Options for MDR-GNB in Critically-ill Patients Polymyxins. Polymyxins acts as detergents of the outer membrane of GNB, exerting bactericidal activity. Aminoglycosides. Tigecycline. Carbapenems. Fosfomycin. Ceftazidime/Avibactam. Meropenem/Vaborbactam. Ceftolozane/Tazobactam. How serious is Mdro? Infection. When a person gets sick because of the bacteria, they are infected with the […]
What is the difference between momentum and velocity?
What is the difference between momentum and velocity? As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component while momentum is (physics) (of a body in motion) the product of […]
What are the 3 levers involved in deep squat?
What are the 3 levers involved in deep squat? The levers that exist in this analysis are the back, the femur, and the shank or lower leg. The levers, as they hinge around the hip and knee joints, form the diagnostic angles used to analyze and discuss the movement. What are examples of second class […]
What should I wear in 20 C weather?
Which liquid would evaporate most quickly at room temperature?
Which liquid would evaporate most quickly at room temperature? Acetone has the weakest intermolecular forces, so it evaporated most quickly. Water had the strongest intermolecular forces and evaporated most slowly. Which type of liquid dries the fastest? The rubbing alcohol evaporated the fastest followed by water and finally vinegar. Olive oil didn#t seem to evaporate […]
Why does O 3 not exist?
Why does O 3 not exist? An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges. The ion would thus be highly unstable and potentially readily lose that outermost electron and return to O3− as the ten inner shell electrons seek to get rid of the additional electron. Why […]
