When the Earth tilts, It puts half of the Earth in Summer and the other half in winter. The half that is faced towards the Sun is Summer, and the side that is faced away is winter. Hope this helps!!
The compound name of this chemical is Titanium(III) oxide
Answer:
pKa = 3.72
Explanation:
Let's consider the dissociation of a generic monoprotic weak acid.
HA(aq) ⇄ H⁺(aq) + A⁻(aq)
For a weak acid, we can find the value of the acid dissociation constant (Ka) using the following expression:
where,
[H⁺] is the molar concentration of H⁺
Ca is the initial concentration of the acid
First, we need to find [H⁺] from pH.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -2.40 = 3.98 × 10⁻³ M
Then,
Finally,
pKa = -log Ka = -log 1.89 × 10⁻⁴ = 3.72
1.velocity-displacement. The first two equations of motioneach describe one kinematic variable as a function of time. ... Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant (s ∝ t2).
The answer is starch because iodine reacts with starch to change the colour to inky blue or black.
All the others are present in milk naturally so I’m assuming they intent starch
