When two substances react what change occurs?

What occurs when an infection upsets the healthy balance of elements in the brain?
An infection upsets this balance, and brain damage can occur when the cells of the brain are either deprived of important nutrients or exposed to toxic levels of particular substances.
What two substances at required for steel to rust?
Steel requires two key substances to rust: moisture (water) and oxygen. When steel is exposed to these elements, an electrochemical reaction occurs, leading to the formation of iron oxide, commonly known as rust. This process is accelerated in the presence of salt or other electrolytes.
Why do substances rust?
Substances like iron rust when they react with oxygen in the presence of moisture, forming iron oxide. This oxidation process weakens the material, leading to the formation of rust. Rusting is an electrochemical reaction that occurs over time when iron is exposed to oxygen and water.
What type of reaction occurs if two substances are chemically combined and there is a release of energy?
Exothermic

When fermentation occurs what substances are available?
Oxygen
Where does most evaporation fall?
Most of the evaporation occurs over bodies of water such as oceans, seas, lakes, and rivers, where the surface area exposed to air is large and water can easily evaporate due to the heat from the sun. These water bodies provide the necessary moisture for evaporation to happen at a significant rate.
What bodies of water makes evaporation occurs?
Water is evaporated from all bodies of water.
When you step out of a bright light into the dark what is the process called that happens to your eyes?
The process is called dark adaptation. It occurs when your photoreceptors in the retina become more sensitive to light in low-light environments after being exposed to bright light.
What Substances that will lost from soil when erosion occurs?
soil
The tanning effect that occurs when a person is exposed to the sun is exposed to the sun is somewhat protective due to?
Increased production of melanin.

A change that occurs when one or more substances changes into entirely new substances with different properties?
Chemical Change.
The attractive force between two bodies of different substances?
The attractive force between two bodies of different substances is known as adhesion. Adhesion occurs due to the molecular attraction between the surfaces of the two materials, leading them to stick together. This phenomenon is commonly observed in various everyday situations, such as water sticking to a glass surface.
