Hey there!:
Volume = 175.4 mL
density = 0.8786 g/mL
mass = ?
Therefore:
D = m / V
0.8786 = m / 175.4
m = 0.8786 * 175.4
m = 154.10644 g
hope this helps!
<span>The number of neutrons bromine will have are equal to
= protons + neutrons
so,
80-35=45</span>
Ca(OH)₂: strong base
pOH = a . M
a = valence ( amount of OH⁻)
M = concentration
Ca(OH)₂ ⇒ Ca²⁺ + 2OH⁻ (2 valence)
so:
pOH = 2 x 0.005
pOH = 0.01
pH = 14 - 0.01 = 13.99
Answer:
Water applied to the surface of a relatively dry soil infiltrates quickly due to the affinity of the soil particles for water. As time passes and the soil becomes wet, the force of gravity becomes the dominant force causing water to move.
Explanation:
