Answer:
7200 kPa
Explanation:
Applying,
PV/T = P'V'/T'................ Equation 1
Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas
Make P' the subject of the equation
P' = PVT'/V'T.............. Equation 2
Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K
Substitute these values into equation 2
P' = (900×8×600)/(2×300)
P' = 7200 kPa
Inhibitors are substances that slow down chemical reactions<span>. </span>
Yes layers of sediment form at the bottom of the ocean.
MnO₂ + 4HCl = MnCl₂ + 2H₂O + Cl₂
n(MnO₂)=0.45 mols
n(HCl)=0.28 mols
0.45 : 0.28 = 1 : 0.622
the reaction equation 1:4
the hydrogen chloride in the lack
n(Cl₂)=n(HCl)/4
n(Cl₂)=0.28/4=0.07 mols
formed 0.07 mols of chlorine
Number 1 is B number 2 is C
