Answer and Explanation:
Meteorologists use meteorological data to assess current temperature and precipitation rates and even make projections of these rates in future times. If high temperature rates combined with low rainfall can cause catastrophic fires to occur, then analyzing data on these factors and making projections on them is essential to prepare for those fires.
A physical change. When a physical change occurs the chemical composition of the substance doesn't change. Some examples of physical changes are melting, freezing, vaporization, and condensation.
Answer:
Gases are easily compressed because of the space between the particles in a gas. ... The pressure decreases because the kinetic energy decreases with the temperature and slower moving particles impact the walls of a contain with less energy.
Answer: To calculate for the enthalpy of formation, it is the sum of all values of products - sum of all values of reactants.
Explanation:
I’m not sure what chemical reaction you are referencing to, but I attached an image below to help you see what I’m saying.
When non-metal atoms ionize they gain electrons.<span> Some examples of this are the halogen elements: F, Cl, Br and I, each, can gain one electron from the respective anions, F-, Cl-, Br-, and I-. O and S, may gain two electrons to form the anions O2- and S2-. This is due to the fact that those elements only need one (in the case of the halogens) or two (in the case of O and S) electrons to reach the most stable configuration of the closest noble gas (with the last shell of electrons full), so they are ready to gain those electrons and form the corresponding ions.</span>
