Answer:
C. NaOH(s) + HCl(aaq) rightarrow NaCl(s) + H2O(aq)
Explanation:
A neutralization reaction may be defined as the reaction where an acid when it reacts with some base, the products formed are a salt and water.
Simply, we can write,
acid + base ---> salt + water
Here in option (C),
NaOH is sodium hydroxide is an base
HCl is hydrochloric acid
NaCl is sodium chloride and is the common salt
H20 is water
So, option C). NaOH(s) + HCl(aaq) -----> NaCl(s) + H2O(aq) is a neutralization reaction.

Answer:
By definition, a percent w/v solution is the measure of weight per 100 mL. 7.5 g/100 mL = 7.5%
Explanation:
Answer:
As age increases, weight increases.
Explanation:
The blue arrow shows the general trend of the dots.
If you trace the path of the arrow, your finger goes to the right, so age (on the horizontal axis) increases.
Your finger also goes up, so weight (on the vertical axis) increases.
Both things are happening at the same time, so, as age increases, weight increases.
Answer:
Associative Evidence
Explanation:
According to the authors, the most effective means of developing associative evidence are instrumental chemistry, microscopy, photomacrography, other optical methods, and morphology. It is used to provide the link between and evidence and individual involved in a crime.
