The rate law for this reaction is [A]².
Balanced chemical reaction used in this experiment: A + B → P
The reaction rate is the speed at which reactants are converted into products.
Comparing first and second experiment, there is no change in initial rate. The concentration of reactant B is increased by double. Initial rate does not depands on concentration of reactant B.
Comparing first and third experiment, initial rate is nine times greater, while concentration of reactant A is three times greater. Conclusion is that concentration of reactant A is squared and the rate is [A]².

2.5 x 10^24 molecules of C4H10
Answer:
113406825 N/m²
Explanation:
The pressure at depth of 11,000 m can be calculated by:
Pressure = Atmospheric pressure + Pressure due to height
Atmospheric pressure = 101325 N/m²
Also,
Where,
is the density of water (
)
g is the gravitational acceleration = 9.81 m/s²
h = 11,000 m
Pressure due to height = 113305500 N/m²
<u>Pressure = Atmospheric pressure + Pressure due to height = 101325 N/m² + 113305500 N/m² = 113406825 N/m²</u>
Hey there!
Molar mass Na2SO4 = 142.04 g/mol
Number of moles:
n = m / mm
n = 25 / 142.04
n = 0.176 moles of Na2SO4
Therefore, use the Avogadro constant
1 mole Na2SO4 ------------------- 6.02x10²³ molecules
0.176 moles Na2SO4 ------------ molecules ??
0.176 x ( 6.02x10²³ ) / 1
=> 1.059x10²³ molecules of Na2SO4
hope this helps!
