Answer: Option (1) is the correct option that is currents deflect to the right due to the rotation of Earth.

Explanation:

The water on the surface of ocean is moved by winds that blow in certain direction because of the Coriolis effect and spinning of the Earth that's why ocean currents in the Northern hemisphere tend to move in the clock-wise direction.

If you increase the solute amount but keep the solution volume the same what
solmaris [256]

Answer: Molarity increases

Explanation:

Molarity, also known as concentration in moles/dm3 or g/dm3, is calculated by dividing the amount of solute dissolved by the volume of solvent. So, Molarity (c) = amount of solute (n) / volume (v)

i.e c = n/v

Hence, molarity is directly proportional to the amount of solute dissolved, and inversely proportional to the volume of solvent.

Thus, at same volume, any increase in solute amount increases molarity while a decrease will also decreases molarity.

Choose the solvent below that would show the greatest boiling point elevation when used to make a 0.10 m nonelectrolyte solution
postnew [5]

Answer is: 1) ccl4, kb = 29.9°c/m, carbon tetrachloride has the greatest boiling point elevation.

The boiling point elevation is directly proportional to the molality of the solution according to the equation: ΔTb = Kb · b.

<span> ΔTb -  the boiling point elevation.
Kb - the ebullioscopic constant.
b - molality of the solution.
So the highest boiling poing elevation will be for solution with highest ebullioscopic constant because molality is the same.</span>

What happens to an ionic compound when it is dissolved in water?
damaskus [11]

Answer:

c

Explanation:

because the ion are Mobil which mean they are free not combined and carry a charge but when they are combined/ fixed in position they can't carry a charge so therefore can't conduct electricity  :)

Calculate the percentrage of neutral form of aspirin that is present in the stomach ph 1.
Korolek [52]

Answer:

The 99.68% of the aspirin is present in the neutral form

Explanation:

Aspirin, Acetylsalicylic acid, is a weak acid with pKa = 3.5

Using Henderson-Hasselbalch equation:

pH = pKa + log [A⁻] / [HA]

<em>Where [A⁻] is the ionized form and HA the neutral form of the acid</em>

<em />

Replacing with a pH of stomach of 1.0:

1.0 = 3.5 + log [A⁻] / [HA]

-2.5 = log [A⁻] / [HA]

3.16x10⁻³ = [A⁻] / [HA] <em>(1)</em>

<em />

A 100% of aspirin is = [A⁻] + [HA]

100 = [A⁻] + [HA] <em>(2)</em>

<em></em>

Replacing (2) in (1)

3.16x10⁻³ = 100 - [HA] / [HA]

3.16x10⁻³[HA] = 100 - [HA]

1.00316 [HA] = 100

[HA] = 99.68%

<h3>The 99.68% of the aspirin is present in the neutral form</h3>
