Answer:
last option is the correct answer
Explanation:
you can see that the chemical NaCl is decomposed or broken into its components Na and Cl.
all other equations have formation of a new compound by reaction of 2 elements or compound
Answer:
If the frequency is doubled, the wavelength is only half as long.
Explanation:
Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.
Answer:
The new volume is 7,606.96 Liter.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in the balloon = 0.918 atm
= final pressure of gas in the balloon = 0.0012 atm
= initial volume of gas in the balloon = 
= final volume of gas in the balloon = ?
= initial temperature of gas in the balloon = 
= final temperature of gas in the balloon = 
Now put all the given values in the above equation, we get:
The new volume is 7,606.96 Liter.
The Bohr Model, which was proposed by Niels Bohr in 1913
Answer:
The answer to your question is Theoretical yield
Explanation:
Theoretical yield is the quantity of a product obtain considering that all the reactants will be converted into products. The theoretical yield considers that the reaction is 100% effective, but this is not true most of the chemical reactions have a yield of 80 % or lower.
