It’s called Avogadro’s number!
I think it's RbCl and CaO
C. Of the products is equal to the reactants.
Good luck out there! :)
Answer:
P₂ = 16.6 atm
Explanation:
Given data:
Initial pressure = 13.0 atm
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 102.0°C (102+273 =375 K)
Final pressure = ?
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
13.0 atm / 293 K = P₂/375 K
P₂ = 13.0 atm × 375 K / 293 K
P₂ = 4875 atm. K /293 K
P₂ = 16.6 atm
Answer:
0.05142 M
Explanation:
Let's consider the neutralization reaction between KHP and NaOH.
KHC₈H₄O₄ + NaOH → H₂O + NaKC₈H₄O₄
12.39 mL of 0.04150 M NaOH were required for the neutralization. The moles that reacted are:
12.39 × 10⁻³ L × 0.04150 mol/L = 5.142 × 10⁻⁴ mol
The molar ratio of KHP to NaOH is 1:1. The moles of KHP that reacted are 5.142 × 10⁻⁴ mol.
5.142 × 10⁻⁴ moles of KHP were in 10 mL of solution. The concentration of the KHP solution is:
5.142 × 10⁻⁴ mol / 10 × 10⁻³ L = 0.05142 M
