<em>Hi there! A simple answer and explanation is below :)</em>
Answer:
A) PET plastic water bottle
Explanation:
Plastic goes through a manufacturing process before being used to make bottles for liquids like milk, soda, motor oil, and shampoo, as well as dry items like pharmaceuticals and nutritional supplements. Plastic is made up of a variety of organic polymers, including polyethylene and ethylene, in its unprocessed condition. In a soft state, plastic can be molded into the desired shape and then cast into a solid stat
Answer:
Equilibrium concentrations of Ammonia and Hhydrogen sulphide are 0.2M respectively
Explanation:
Equilibrium constant is represented by the symbol k, it may be in terms of pressure (Kp) or concentration (Kc). Equilibrium constant is the ratio of the equilibrium concentration of the products of a reaction to the equilibrium concentration of the reactants with each concentration raised to the power of its corresponding coefficients.
There are rules guiding the writing of equilibrium constant, one of them is that the equilibrium constant or concentration for pure liquid or solid is 1

Explanation:
The experiment of Ernest Rutherford involved the bombardment of a thin gold foil with alpha particles from a radioactive source. A zinc sulphide screen was used to follow the movement of the alpha particles.
It was discovered that most of the alpha particles followed a straight path through the gold foil. Some of them were scattered through large angles and few were even scattered in the backward direction.
Since alpha particles were heavier than electrons, they must have been deflected by very strong forces.
These experimental evidences led to the conclusions stated in the question.
Ca(OH)2
Make sure your charges are balanced when you write the compound. Ca has a +2 charge and OH has a -1 charge so you need 2 of OH.
