We categorise reactions by the direction of this energy change. If energy is released by a reaction, the reaction is exothermic. If energy is absorbed by a reaction, the reaction is endothermic. When ...

A presenter-led science video investigating exothermic and endothermic reactions, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge.

The slideshow describes an exothermic reaction between dilute sodium hydroxide and hydrochloric acid, and an endothermic reaction between sodium carbonate and ethanoic acid.

We describe the general background and the recent advances in research on underwater photosynthesis of leaf segments, whole communities, and plant dominated aquatic ecosystems and present contemporary ...

Photosynthesis is the process by which plants, algae and certain types of bacteria synthesise carbohydrates from carbon dioxide and typically water, using light as an energy source. The process ...

This was done (a) to determine how low pH affects photosynthesis, related physiological parameters, and mineral nutrient profiles; and (b) to understand the mechanisms by which low pH may cause a ...
