Answer:
it gives up electrons B. because the bond between the electrons is not very strong due to how few of them there are
Explanation:
NaCl + AgNO are the reactants since the reactants are always on the left side of the yield.
Answer:
10.10
Explanation:
Step 1: Write the basic dissociation reaction for pyridine
C₅H₅N(aq) + H₂O(l) ⇌ C₅H₅NH⁺(aq) + OH⁻(aq) Kb = 1.9 × 10⁻⁹
Step 2: Calculate [OH⁻]
For a weak base, we will use the following expression.
[OH⁻] = √(Cb × Kb) = √(9.2 × 1.9 × 10⁻⁹) = 1.3 × 10⁻⁴ M
Step 3: Calculate pOH
We will use the definition of pOH.
pOH = -log [OH⁻] = -log 1.3 × 10⁻⁴ = 3.9
Step 4: Calculate pH
We will use the following expression.
pH = 14 - pOH = 14 - 3.9 = 10.10
Answer:
A
Explanation:
B describes a strong base, C just isn't true there are only 7 strong acids, D describes a weak acid
subatomic particles are measured using amu (atomic mass unit)
