To finish calculating the frequency of an electromagnetic wave, you need the wavelength
Dilution formula:
mv = MV
where one side is concentration × volume BEFORE dilution and the other side is concentration × volume AFTER dilution.
(100mL) × (12 M) = (500mL) × (X)
(1200 M·mL) = (500mL) × (X)
(1200 M·mL) / (500mL) = X
2.4 M = X
<span>A fizz saver forms an airtight seal around the now-upsidedown soda bottle, and the pressure exerted by the drink and the atmospere outside pushes out the drink through the slightly-elevated spout. The CO2 gas does not fizz out because it stays at the bottom of the upside-down bottle. Thus the CO2 gas is trapped and the drink is carbonated at a longer time.</span>
A chemical reaction of exothermic kind releases energy in the form of heat and light.
We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.
We are required to find number of grams of reactant that has been consumed
It is also given that 880J of energy is released
Hence, grams of reactants consumed is 880/27.4gm
