The answer is A, which is often known as the red shift. It is the displacement of spectral lines toward longer wavelengths.
Answer: 44.8 L
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atm respectively.
To calculate the moles, we use the equation:
1 mole of occupies volume = 22.4L at STP
Thus 2 moles of magnesium react with=
Thus the volume of molecules of nitric oxide gas is 44.8 L.
The products and reactants weigh the same since u have to balance out the equation to have an equal number of molecules on bothsides
The answer would be D. I would guess but I could be wrong haha
