Answer:
this is a oxidation reaction
product is magnesium oxide
the balanced equation is
2Mg + O2 -> 2MgO
The Arrhenius definition of acid-base reactions, which was devised by Svante Arrhenius, is a development of the hydrogen theory of acids. ... An Arrhenius base is a substance that dissociates in water to form hydroxide (OH -) ions. In other words, a base increases the concentration of OH - ions in an aqueous solution.
B:Molecules must collide.
Why: They have to collide so the chemical bonds can break.
All of the factors listed above, except food can be classified as abiotic factors. Food (the presence of plants,animals and other organisms in the ecosystem and their complex relationships) is the biotic component of the ecosystem.
These factors affect the distribution, survival and genetic characteristics of the populations. The lack of water, shelter and space can prevent certain species from living in the ecosystem or cause strong pressure of the natural selection and shape the genetic structure of the population.
Complex biotic relationship also influence behavior, presence and genetic structure of the populations.
Colligative
properties calculations are used for this type of problem. Calculations are as
follows:<span>
ΔT(freezing point) = (Kf)(molality)
ΔT(freezing point)
= 1.86 °C kg / mol (molality)
</span>Tf - 102.08 = 1.86m
Tf = 1.86m + 102.08
The concetration of the solution is needed in order to obtain a specific value.
