Does temperature affect order of reaction? Effect of Temperature on Reaction Rates. The orders of reaction are independent of temperature – orders change only when the reaction changes. Thus, the entire temperature dependence of a reaction, as expressed in a rate law, is found in the rate constant, k. How do you find the maximum […]

Ability to form alloys with metals. Usually brittle. Is graphene a semi metal? —Graphene is a semi-metal and is a zero-gap semiconductor (Fig. 4a). In addition, bilayer graphene’s electronic band […]
How do humans impact the chaparral biome?
How do humans impact the chaparral biome? California’s Chaparrals have been negatively impacted mainly by human development. These fires, when too frequent, easily destroy many Chaparral regions. Other significant contributing human impacts on the Chaparral include the creation of water diversions, damming, and competition by invasive plant and animal species. What animals live in Chaparral? […]

How do you know the charge of valence electrons?
How do you know the charge of valence electrons? Since a chemical bond has two electrons, the “number of bonding electrons divided by 2” is by definition equal to the number of bonds surrounding the atom. So we can instead use this shortcut formula: Formal Charge = [# of valence electrons on atom] – [non-bonded […]
