How does oxygen turn into ion? Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-. Can oxygen ion be positive? Thus, an energetic electron passing near or through an oxygen molecule, […]
Which of the following is a case of steady state heat transfer?
Which of the following is a case of steady state heat transfer? Solution(By Examveda Team) Heating of building in winter-Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows. Which of the following is a case of heat transfer by radiation? Solution(By […]
What is the principle of mass spectrograph?
What is the principle of mass spectrograph? “The basic principle of mass spectrometry (MS) is to generate ions from either inorganic or organic compounds by any suitable method, to separate these ions by their mass-to-charge ratio (m/z) and to detect them qualitatively and quantitatively by their respective m/z and abundance. What is the use of […]
How can you tell if MAP sensor is bad?
How can you tell if MAP sensor is bad? What to look out for in a failing MAP sensor Rich air-fuel ratio: Look for rough idle, poor fuel economy, slow acceleration and a strong smell of gasoline (especially at idle) Lean air-fuel ratio: Look for surging, stalling, lack of power, hesitation on acceleration, backfiring through […]

Where are the inner transition elements?
Where are the inner transition elements? The inner transition metals are found in the f-block, usually put at the bottom of the Periodic Table. These elements were sometimes called rare earth metals due to their extremely low natural occurrence. What are transition metals and their properties? The transition metals have the following physical properties in […]
Does gravitational force increase with distance?
Does gravitational force increase with distance? Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. What happens to the […]
What is the cause of resistance?
What is the cause of resistance? Resistance is caused in a conductor by the free electrons. These free electrons collide with each other and with the ions and atoms that oppose their free movement. This obstruction is known as resistance. Does temperature increase resistance? As electrons move through a metal conductor, some collide with atoms, […]
Who is liable if roofer falls off my roof?
Who is liable if roofer falls off my roof? Legally, the responsibility varies from case to case. There are cases where the building owner may be legally liable for the incident. For example, if the incident has been proven to be caused by the building owner’s negligence, they are liable. You should have a contract […]
What factors affect collision theory?
What factors affect collision theory? Key Takeaways Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate. What are the 5 major factors […]
