Explanation:
colligative properties are properties that depend on the concentration of molecules or ions of the solute, but not on the identity of the solute. Colligative properties include lowering of vapour pressure, boiling point elevation, depression of the freezing point, and osmotic pressure
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respirationconverts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
We can write the overall reaction of this process as:
6H2O + 6CO2 ----------> C6H12O6+ 6O2
Most of us don't speak chemicalese, so the above chemical equation translates as:
six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen
For a given reaction the half-life, t1/2, of a reactant is the time required for its concentration to reach a value that is the arithmetic mean of its initial and final (equilibrium) value.
Half-life is constant for first-order reactions.
t1⁄2 =
ln 2
k
Half-life is not constant for second-order reactions but rather it varies with initial concentration and k.
t1⁄2 =
1
k·[A]o
half-life → vrijeme poluraspada
For a simple radioactive decay process, half-life, t1/2, is defined as the time required for the activity of a given radioactive isotopes to decrease to half its value by that process.
N = N0 / 2
The half-life is a characteristic property of each radioactive isotope and is independent of its amount or condition.
limiting reactant → mjerodavni reaktant
Limiting reactant is a reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when the entire limiting reagent is consumed. These other reactants are present in excess.
reactant → reaktant
Reactants are initial materials in a chemical reaction.
half-cell → polučlanak
Half-cell is a part of galvanic cell in which oxidations or reduction of an element in contact with water or water solution one of its compounds.
half-wave potential → poluvalni potencijal
Half-wave potential (E1/2) is a potential at which polarographic wave current is equal to one half of diffusion current (id). In a given supporting electrolyte, the half-wave potential is unique for each element and its different valence states and chemical forms. Observation of a current peak at a specific half-wave potential therefore identifies the chemical species producing the current.
Answer:
4 Sb (+3) + 2 Br (2) O (3) ----> 4 SbBr + 3 O(-2)
In the equation, place the valences in parentheses and the stoichiometric balance numbers so that the reaction is balanced, place them in bold.
Explanation:
In this chemical equation it seems to me that the valences of BrO are wrong.
That is why I will complete the equation, demonstrating the chemical reaction, and also use the appropriate valences.
Assuming that Sb has a valence of +3 and that the Br that appears in the form of oxide with oxygen (valence -2) has a valence of +3 (because -3 does not exist as valence or oxidation state of bromine).
