Answer:
<h2>9 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 3 × 3
We have the final answer as
<h3>9 kg.m/s</h3>
Hope this helps you
Answer:
B
Explanation:
cause surface area of solute is not necessary for solution
Answer:
Ksp = 3.24 x 10⁻⁴
Explanation:
The dissociation equilibrium for a generic salt AB is:
AB(s) ⇄ A⁺(aq) + B⁻(aq)
s s
For instance, the expression for the Ksp constant is:
Ksp = [A⁺] [B⁻] = s x s = s²
According to the problem, 0.0180 mol of the salt is soluble in 1.00 L os water. That means that the solubility of the salt (s) is equal to 0.0180 mol per liter.
s = moles of solute/L of solution = 0.0180 mol/L
Thus, we calculate Ksp from the s value as follows:
Ksp = s² = (0.0180)² = 3.24 x 10⁻⁴
Geosphere >> Which is Earth's entire solid body..
Hydrosphere >> Which is all the "liquid" water on Earth..
Atmosphere >> Which is the few layers of "gasses" that are surrounding Earth..
Cryosphere >> Which is all the "frozen" water on Earth..
Biosphere >> Us! All the living organisms on Earth..
