Answer:
they both have seven electrons in the outer shell
they are all just one electron shy of having full shells
Answer:
Velocity = wavelength x frequency
Wavelength = Velocity / frequency
From the above,
Wavelength is inversely proportional to frequency since the velocity of electromagnetic wave is constant.
So as the wavelength increases, the frequency decreases and vice versa

Answer:
We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.
So 1 g water will contain 1/18 moles of H2O molecules.
Now 15 g of water will contain 15/18 moles of H2O.
So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

Answer: The initial temperature was 263 K
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.939 atm
= final pressure of gas = 1.00 atm
= initial volume of gas = 9.40 L
= final volume of gas = 10.0 L
= initial temperature of gas = ?
= final temperature of gas =
Now put all the given values in the above equation, we get:
Thus the initial temperature was 263 K
