1. Tributary
2. Erosion
3. Where a river turns
Arrhenius concept just states that if a solution dissociates and forms H+ ions then its and acid, but if it dissociates and forms OH- than it's a base.
So the answer to your question would be D. An Acid
Answer:
See the explanation
Explanation:
We have to start by analyzing the molecule. In the molecule, we have <u>two types of isomerism</u>. In the double bond, we can have <u>E or Z isomerism</u>, and additionally, we have a <u>chiral carbon</u> (a carbon with 4 different bonds) (See figure 1). With this in mind, we can have <u>4 possible isomers</u>.(See figure 2).
<u>a) (3S)-2-(E)-ichthyothereol</u>
<u>b) (3R)-2-(E)-ichthyothereol</u>
<u>c) (3R)-2-(E)-ichthyothereol</u>
<u>d) (3R)-2-(Z)-ichthyothereol</u>

PH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution.
Heat required = Q = 40 kcal
<h3>Further explanation</h3>
Given
mass of 500 g ice
Required
Heat required
Solution
The heat to change the phase can be formulated :
- Q = m.Lf (melting/freezing)
- Q = m.Lv (vaporization/condensation)
Lf=latent heat of fusion
Lv=latent heat of vaporization
Lf for water = 334 kj/kg=6.01 kJ/mol = 80 cal/g
Phase change(ice to water)
Q= 500 g x 80 cal/g
Q = 40 kcal
