A compound has the empirical formula CH2O. If the compound’s molecular mass is 180 g/mol, determine the molecular formula of the

Umnica [9.8K]

The molecular formula will be a multiple of the empirical CH2O. One unit of CH2O has a mass of 12+2*1+16 = 30 g. This means that if our compound has a molecular mass of 180 g/mol, we can divide 180 / 30 = 6 units, and our compound has 6 units of CH2O. This means that its molecular formula is C6H12O6.

An atom that has one or two valence electrons is most likely to be - Nonreactive only

meriva

Answer:

C) Highly reactive

Explanation:

An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion

Calculate the energy of one photon of yellow light that has a wavelength of 5.89x10^-7m.

Viktor [21]

Answer:

E = energy = ? ,

λ = Wavelength = 5.89 × 10^-7 m —> = 589 ×10 ^-9 m ,

h =Planck constant = 6.63 × 10^-34 J.s ,

f = frequency of photo/ electromagnetic radiation = c/λ ,

c = Speed of light in a vacuum = 3 × 10^8 m/s

___o___o____

$E = hf \\ \\ E = h \frac{c}{λ} \\ \\ E = 6.63 \times {10}^{ - 34} \frac{3 \times {10}^{8} }{5.89 \times {10}^{ - 7} } \\ \\E = \frac{6.63 \times {10}^{ - 34} \times 3 \times {10}^{8} }{5.89 \times {10}^{ - 7} } \\ \\ E = \frac{663 \times {10}^{ - 36} \times 3 \times {10}^{8} }{589 \times {10}^{ - 9} } \\ \\ E = \frac{1989 \times {10}^{ - 28} }{589 \times {10}^{ - 9} } \\ \\ E = 3.37691 \times {10}^{ - 19} J$
