Ways in which chemical reactions can be identified?
Chemical reactions can be identified by changes in color, temperature, or the formation of a precipitate. Additionally, observing the release or absorption of gas, or changes in pH can also help identify chemical reactions. Analyzing the starting materials and products using techniques like spectroscopy or chromatography can provide further evidence of a chemical reaction.
Which energy change occurs in an operating voltaic cell?
Chemical energy is spontaneously converted to electrical energy.
New substances in a chemical reaction?
New substances are formed in a chemical reaction when chemical bonds are broken and rearranged. This process results in the formation of different molecules with unique properties compared to the original reactants. The new substances are identified by changes in physical and chemical properties such as color change, gas production, or temperature change.
Which type a biological agent was recently identified as an inefective chemical?
prion
Is temperature change chemical or mechanical?
chemical
What is 19celsius in Fahrenheit?
a chemical must be stored at 19 celsius. what is the temperature in degrees fahrenheit?
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
Who do atoms form chemical bonds?
Atoms spontaneously from chemical bonds in order to be stabilize as a molecule/lattice and reduce its energy.

What does tempture mean?
Temperature refers to the degree of hotness or coldness of an object or the environment. It is typically measured using a scale such as Celsius or Fahrenheit. Temperature can affect various physical and chemical properties of substances.
Several million chemical elements have been identified?
No.

How are Shigella bacteria identified?
Shigella are identified by a combination of their appearance under the microscope and various chemical tests.
What does it mean if chemical has a flashpoint of 92º Fahrenheit?
The flash point of any material is the temperature at which the substance gives off enough vapors that it could be ignited by a spark or open flame. A flash point of 92F (33C) would indicate the substance is probably a solid or semi-solid fuel source much like alcohol gelatin, (Sterno). Note: It will actually light at a lower ambient temperature because the ignition source (usually a match) actually raises the temperature of the gel to the flash point and the continuing flame then raises it to the ignition temperature. (usually around 500-900 degrees F)
What is 97 Celsius?
97 degrees Celsius is a high temperature that is typically used for processes such as cooking, sterilization, or some chemical reactions. It is equivalent to 206.6 degrees Fahrenheit.
