Answer:
A compound is just pure that is composed of elements that are chemically bonded in definite proportions
andd solution is umm well its a homogenous so basically saying
that it all just stays the same all the way through
Explanation:
im not sure how else to explain it haah hope this helped :P
Answer:
Salts will be formed and the pH of the new mixture will fall.
Explanation:
What should be: The reaction mixture should be added to the cold acid solution.
The error: Cold acid solution was added to the reaction mixture.
What happens with this?
The neutralization of a solution creates salts. The combination of positive and negative ions in the reaction also forms water. Assuming the pH of the reaction mixture was neutral before the addition of the acid, after the addition of the acid solution the pH will drop. Recall that a neutral solution has a pH of 7. So the pH of this new solution will drop to less than 7 because of the addition of an acid.
If the required procedure for the chemical process was followed, the reaction mixture added to the cold acid would have resulted in a stronger base solution. In other words, the pH of the new solution would be higher.
The correct option is C.
Analysis of experimental results involves using appropriate statistical and mathematical formulae to interpret the results obtained during the experiment.
The raw data obtained during the experiment has to be treated in this way in order derive information from it.
Based on the above descriptions provided for silicon, I'm assuming that you want to know what silicon is categorized as, in the periodic table, since it posses some properties of metals and nonmetals it would be classified as a mettaloid or a semi metal.
