Scientists often communicate their research results in three general ways. but this only asks for 2 so I'm giving 2 haah anyway .One is to publish their results in peer reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to there presentations or presentations in general.
hope this helped
Answer:
An acid
Explanation:
According to the Arrhenius theory of acids and bases "an Arrhenius acid is a compound that increases the concentration of H+ ions that are present when added to water"
The correct answer is C. It was based on the thoughts of an early philosopher.
Explanation:
An atom is a basic and smallest unit that composes matter and that determine the properties of elements. Regarding the development of ideas related to atoms these did not begin in science but in philosophy; indeed the first person that proposed matter or elements were composed of certain smaller units was the philosophers Leucippus and his pupil Democritus in Ancient Greece, who stated atoms were eternal, infinite and defined the qualities of an object, idea that was supported by other Greek philosophers. But it was not until 16th and 17th centuries after the Middle Ages that the term re-emerged and until the 19th century it was officially proposed and there were experiments by scientists that later became a theory. Therefore, the development of the earliest idea about attoms differs from later work of scientists is that the earliest idea was based on the thoughts of an early philosopher.
<u>Answer:</u> The pH of the solution is 1.703
<u>Explanation:</u>
We are given:
Concentration of monochloroacetic acid = 0.31 M
The chemical equation for the dissociation of monochloroacetic acid follows:
<u>Initial:</u> 0.31
<u>At eqllm:</u> 0.31-x x x
The expression of 
for above equation follows:
![K_a=\frac{[H^+][C_2H_2ClO_2^-}}{[HC_2H_2ClO_2]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BH%5E%2B%5D%5BC_2H_2ClO_2%5E-%7D%7D%7B%5BHC_2H_2ClO_2%5D%7D)
We are given:
Putting values in above equation follows:
Neglecting the negative value of 'x' because concentration cannot be negative.
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
Hence, the pH of the solution is 1.703
