Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Answer:
0.823 M was the molarity of the KOH solution.
Explanation:
(Neutralization reaction)
To calculate the concentration of base , we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
0.823 M was the molarity of the KOH solution.
Answer: 1.0 × 10-14
Explanation:
Pure water, represented as
H2O --> [H+] + [OH -]
undergoes a reversible reaction in which both H+ and OH- are generated.
The equilibrium constant for this reaction, called the water dissociation constant, Kw, is 1.0 × 10-14 at 25 °C.
Answer:
the answer is D
Explanation:
Air over the beach heats up, rises, and is replaced by cool, denser ocean air
The ocean heats up much slower and becomes relatively cooler than the beach making it a high pressure zone. The air moves from the water to the land each morning forming a sea breeze. These pressure zones might equal out later in the day and the winds may diminish. ... A sea breeze blows from the ocean towards the beach.
