What is hydrogen bonding in water quizlet? What is hydrogen bonding in water ? In water, the weak bond formed by the attraction of opposite charges between hydrogen and oxygen from another molecule. Hydrogen bonding help hold together many large molecules, such as proteins weak bond. You just studied 22 terms! What role does hydrogen […]
What is a feedback loop in anatomy?
What is a feedback loop in anatomy? A feedback loop is a biological occurrence wherein the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback). Feedback loops are important because they allow living organisms to maintain homeostasis. What is a feedback loop in a system? A feedback loop is […]
How big should a mirror be above a fireplace?
What happens when intensity is doubled?
What happens when intensity is doubled? Any change in the energy of the photons will not change the intensity. So if intensity is doubled, the no. of photons incident on the surface will be doubled and as a result more photoelectrons will be ejected. What is the value of maximum usable frequency when the incident […]

Why is hydrogen so special?
Why is hydrogen so special? Hydrogen is a colorless gas that is so much lighter than air that it can actually escape the gravitational pull of the earth and shoot off into space. Hydrogen is also the first element on the periodic table and has only on proton and one electron. Hydrogen does not have […]
How does distance from the ocean affect climate?
How does distance from the ocean affect climate? Distance from the sea – Oceans heat up and cool down much more slowly than land. This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude. Why are coastal areas more stable climates? […]
Why can hydrogen only have two valence electrons?
Why can hydrogen only have two valence electrons? Because hydrogen only has one electron surrounding its nucleus, its valence shell is the first energy shell, which only needs two electrons to be full. Hydrogen tends to form covalent bonds because a single covalent bond will fill its shell. How many valence electrons are present in […]
