Calculate the density of a cube of iron that measures 3.50cm, 0.755 cm, 2.25cm on each side and weighs 47.0g?
laila [671]

Answer: 7.90 g/cm^3

Explanation:

Density = Mass / Volume

The first step is to find the volume by multiplying the three measures of the cube that have been provided.

3.50 x 0.755 x 2.25 = 5.95 cm^3

Now we can plug the numbers into our equation.

Density = 47.0g / 5.95 cm^3

Density = 7.90 g/cm^3

Which property determine am atoms ability to attract electrons shared in a chemical bond?
brilliants [131]
Hello there!

Electronegativity is what determine's an atoms ability to attract electrons shared in a chemical bond.Ionization, atomic radius, and also <span> ionic radius both would not determine this as they wouldn't have any similar bond that would attract.
</span><span>
Your correct answer would be (option c)

</span><span>A. ionization 

B. atomic radius

C. electronegativity

D. ionic radius

How to calculate the frequency of an ion
sergij07 [2.7K]

solution:

You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters. (1 nm = 1.0 x 10^{-9} m)

v=c\lambda \\v= (3.00 \times 10^8 m/s)/(6.9\times 10^-7 m) \\v = 4.35 \times 10^{14} s^{-1}
