Answer;
- It will sink because soap disrupts the inter-molecular forces of water
Explanation;
-A light twig is barely floating on the surface of water. if a drop of dish washing detergent is added near it then it will sink because soap disrupts the inter- molecular forces of water.
-The twig was initially floating due to the force of surface tension created by the inter-molecular forces between water molecules. When soap is added to the water, the twig will be driven to sink by the disruption of the water's surface tension. This is because soap is a surfacant that is amphipathic and thus disrupts the inter-molecular forces between water molecules that are responsible for surface tension.

B.) 0-14
C.) 1-14
D.) 1-12
-log[H+ ] + -log[OH- ] = -log[10-14]
pH + pOH = 14
So pH = 14 – pOH and pOH = 14 – pH
the correct answer is B.) 0-14

Answer: The isotope will be represented by symbol .
Solution:
The isotope of an element is represented by:
X = Symbol of an element
Z = Atomic Number of that element = Total number of electrons or protons
A = atomic mass of that element = Z+ total number of neutrons
So the uranium isotope with atomic mass of 238 and atomic number of 92 will be written as:
