Option C. Predicting the boling point of a liquid, given its pressure.
The boiling point is the temperature at which the vapor pressure of a substance in liquid state equals the pressure of the environment. At this point the liquid changes into vapor. Then, we are dealing with physics properties, which means that to predict the boiling point of a liquid the chemist must have an understanging of physics.
After reading all the options represented above, I nodiced that four of them are connected to chemistry, and the only activity that was performed by a chemist is primarily based on an understanding of physics is the third option from the box. C)predicting the boiling point of a liquid, given its pressure while sdudying physics you often come across with such tasks where you need to find the boiling point by using the capability of reservoir with water and its size etc.
The littoral zone of a lake is the area closest to the shore. It has very little biological activity but includes a lot of oxygen. The water in the lake's littoral zone is freshwater, free of living organisms such as plants and fish.
Both aluminum and chlorine have known charges, which are +3 and -1 respectively. To make them cancel each other out in charge, you would need 3 chlorine and for one aluminum, therefore would be correct
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
would be correct
