Answer:
0.01395mol Cr2O3
Explanation:
the molar mass of Cr2O3 is 151.9904 g/mol
2.12g Cr2O3 x 1 mol/151.9904g = 0.01395mol Cr2O3
Explanation:
(a) BCl3= sp² hybridization
(b) AlCl4- = sp³ hybridization
(c) CS2 = sp hybridization
(d) GeH4 = sp³ hybridization
Answer:
Partial Pressure Formula
The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+… +Pn. + P n . The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.
Explanation:
Answer: He theorized that all material bodies are made up of indivisibly small “atoms.” Aristotle famously rejected atomism in On Generation and Corruption. Aristotle refused to believe that the whole of reality is reducible to a system of atoms.
Explanation:
Answer:
There are 4 other factors that affect the rate of reaction which may be responsible for the slowness of zinc powder namely :
1. concentration or pressure of a reactant.
2. temperature.
3. nature of the reactants.
Explanation:
There are 5 factors that affect reaction rates:
1. surface area of a solid reactant.
2. concentration or pressure of a reactant.
3. temperature.
4. nature of the reactants.
5. presence/absence of a catalyst.
