Answer:
A. V2=P1V1/P2
Explanation:
Robert Boyle law stated that pressure of a particular quantity of basis inversely varies with respect to the volume provided that the temperature is constant. It is expressed as
PiV1 = P2V2,
Where
V2= final volume
V1= initial volume
P1= initial pressure
P2= final pressure
Making V2 subject of formula we have
V2=P1V1/P2
This should be most likely true
4FeS₂ + 11O₂ → 2Fe₂O₃ +8SO₂
What happen if FeS₂ is added to the reaction is that
The reaction will shift in the direction of the products
<u><em>Explanation</em></u>
- FeS₂ is a reactant in reaction above .
- When more of reactant added to a system at equilibrium, it increases the concentration of reactant molecules.
- According to collision theory,this increase the number of collisions per second of reactant molecule and therefore more product is formed.
Answer: BF3
Explanation: boron needs 4 electron to obtain octet and Fluorine has just one. For the valence shell to be completely filled it will have to form BF4- with 4 fluorine atom surrounding it.
Answer:
Sulfur has the same amount, like all the other elements in group 16, has six valence electrons.
