The balanced chemical equation representing the neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH),
This reaction is exothermic that is it proceeds by the release of heat energy. This heat energy is lost to the surroundings. This is the reason for the warming up of the beaker where the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) takes place. The enthalpy of such reaction will be negative as the reaction is exothermic.
answer: Surface water in nearby areas can become polluted.
Explanation:
<span>Question: Organic chemistry is the study of compounds containing?
Answer: (A) Carbon
Organic chemistry is the study of compounds that contain the element carbon, or the study of carbon-containing molecules and the compounds they form. An entire branch of chemistry (carbon chemistry) is dedicated to this subject. Which means carbon is quite important, after all it is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and Organic compounds together scientists can learn more about life, the human body, and how it works!</span>
Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>

The number of protons tells you which element the atom is. The number of protons is the element number (Hydrogen - 1, Helium - 2, etc.).
