Photosynthesis is a chemical reaction that absorbs energy from the sun and places it into sugar molecules called glucose. This glucose is then sent to... Learn more about this topic: Balanced Chemical Equation for Photosynthesis from Chapter 17/ Lesson 22 ...
What is a reaction that absorbs energy? How do cells use the energy released from ATP? What about the structure of ATP makes it useful as the energy currency of cells? What is the function of the cytoplasm in a cell? What process brings energy to the biosphere?
Electromagnetic radiation in the form of light is released when an electron loses energy. When an electron absorbs energy, it gets excited and moves... Learn more about this topic: Excited State in Chemistry | Definition & Example from
Chemists often need to know how much heat energy a particular reaction releases or absorbs. This measurement helps them understand more about why the reaction occurs and helps them make useful predictions. Calorimeters are instruments that measure the amount of heat released or absorbed by the conte...
(O2) using electricity. This process, called water electrolysis, is a promising option for carbon-free hydrogen production since the electricity can be sourced from nuclear or renewable energy, such as wind and solar. Scientists and engineers are working to improve and lower the cost of hydrogen...
Types of Bleach There are two main classes of household bleach: chlorine bleaches and non-chlorine bleaches (aka oxygen bleach). All of these bleaches are in a class of chemicals known as oxidative agents, meaning that they cause a chemical reaction called oxidation when they come into cont...
The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible lig...
An x-ray or CTmay show thinned bones or a fracture. You may be given contrast liquid to help the bones show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can ...
When a photon of light hits the reaction center, a pigment molecule such as chlorophyll releases an electron. The released electron escapes through a series of protein complexes linked together, known as an electron transport chain. As it moves through the chain, it generates the energy to produ...
3. A photoinitiator is a substance that absorbs radiant energy and produces reactive intermediates that initiate polymerization through chemical changes.It is the main ingredient required for any UV curing system.Photoinitiators can be divided into hydrogen capture type and split type: the hydrogen capt...
