Answer:
327.5 mmHg
Explanation:
By Boyle's law, P1V1=P2V2
10 L * 655 mmHg = 20 L * x
solve for x
x= (10*655)/20
x=327.5 mmHg
When Be(OH)₂ dissolves it dissociates into the following ions
Be(OH)₂ --> Be²⁺ + 2OH⁻
molar solubility is the number of moles that dissolve in 1 L of solution
If the molar solubility of Be(OH)₂ is 'x', molar solubility of Be²⁺ and OH⁻ ions are x and 2x respectively.
ksp is solubility constant for Be(OH)₂
ksp = [Be²⁺][OH⁻]²
6.92 * 10⁻²² = [x][2x]²
4x³ = 6.92 * 10⁻²²
x³ = 1.73 * 10⁻²²
x = 5.57 * 10⁻⁸ mol/L
molar solubility of Be(OH)₂ is 5.57 * 10⁻⁸ mol/L
Answer:
This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. ... Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe.
Explanation:
Answer:
<h2>1.8 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
volume = 3 cm³
density = 0.6 g/cm³
We have
mass = 0.6 × 3 = 1.8
We have the final answer as
<h3>1.8 g</h3>
Hope this helps you
