Answer:
Kₐ = 9.9 × 10⁻³
Explanation:
HClO₂ + H₂O ⇌ H₃O⁺ + ClO₂⁻
0.080 × 1.43 = 0.1144
So, at equilibrium,
[H₃O⁺] = [ClO₂⁻] = 0.1144
[HClO₂] = 1.43 – 0.1144 = 1.316
Kₐ = {[H₃O⁺][ClO₂⁻]}/[HClO₂]; Substitute values
Kₐ = (0.1144 × 0.1144)/1.316 Do the operations
Kₐ = 9.9 × 10⁻³
Answer:
Step 1
1 of 2
V = m / D; V (nugget of gold) = 50 g / 5.0 g / cm 3 = 10 cm3; V (nugget of iron pyrite) = 50 g / 19 g / cm3 = 2.63 cm 3
Result
2 of 2
Due to these results you can conclude that nugget of gold which volume is 10 cm3 is bigger than volume of nugget of iron pyrite which is 2.63 cm3.
Explanation:
Q=mcΔT
q=(125g)(0.446 J/(g x °C))(78°C - 23.5°C)
q=(125 g)(0.446 J/(g x °C))(54.5°C) (Be sure to cancel all similar units)
q= 3038.375 J
<span>I believe that in this
case the controlled parameter is the type of animal that they are observing.
There are a lot of animals in the ocean, therefore to have a scope of their
study of observation, they are controlling or limiting their observations on
the whale alone. Hence the controlled parameter is the type of animals, whales.</span>
