What else can I help you with?
In what phase or state do most elements occur naturally?
Solid
In which phase do most elements occur at room temperature?
Most metals at room temperature are in the solid phase. Gold is the most malleable and ductile of all known metals.
What is normal phase berkelium?
Normal phase berkelium is solid. It is a radioactive metallic element that is part of the actinide series. Berkelium does not occur naturally on Earth and is primarily produced in nuclear reactors.
What type of change occur when water changes from a solid to a liquid?
its a phase change
What nutrient provides the medium for chemical reactions to take place?
Many chemical reactions occur in water solutions. But a reaction can be realized also in solid or gaseous phase.
What phase occur after s phase?
G2
What is promethium phase at room temperature?
Promethium does not occur naturally on Earth and is primarily synthetic. At room temperature, promethium is expected to be a solid metal.
When heat is added to a situation what 3 things happen?
- the volume increase- the density decrease- a chemical reaction may occur- a change of phase is possible
What phase does the lunar eclipse occur?
full moon phase
What elements and compounds can move from on phase to another?
Elements and compounds can move from one phase to another through physical processes like melting, freezing, evaporation, condensation, sublimation, and deposition. For example, water can move from a liquid phase to a gas phase during evaporation. Additionally, some compounds can change phases through chemical processes, such as sublimation of iodine from a solid to a gas.
What phase of matter is fluorine naturally in?
Liquid air
What is the differences of a chemical change and a physical change?
Chemical changes occur when the elements, their valences, and their amounts change. 4H + O2 => 2H2O is a chemical change because the valences change from unfilled to shared. Physical changes occur when the material phase changes. In fact, in 4H + O2 => 2H2O we also have a physical change...from gas to liquid water (in most cases). NOTE: That there was a chemical change here is incidental, the phase change is the physical change.
