Answer:

3kg

Explanation:

Sand, also known as silicon dioxide, is the main component of glass. If a glass blower used 10 kg of sand, combined with .5 kg of sodium carbonate and 1.5 kg of calcium oxide to produce a glass bowl with a mass of 9 kg, how much material was wasted?

mass of sand=10kg

mass of sodium carbonate=0.5kg

calcium carbonate=1.5kg

glass bowl=9kg

SiO2+CaO+NaCO3----->Glass bowl+residue

10+0.5+1.5=9+x

x=12-9

x=3kg

the mass of material  wasted is 3kg

A prism refracts white light into rainbow colors because
gogolik [260]

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum. Water droplets in the air can act in a manner similar to that of a prism, separating the colors of sunlight to produce a spectrum known as a rainbow.

One photon of a certain type of light has an energy of 7.32x10^-19 J. a.) What is the frequency of this type of light? b.) What
iren [92.7K]

Answer:

f = 1.1041 × 10¹⁵ s⁻¹

λ = 2.72  × 10⁻⁷ m

Explanation:

Given data:

Energy of photon = 7.32 × 10⁻¹⁹ J

Wavelength = ?

Frequency = ?

Solution:

Formula

E = h. f

h = planck's constant = 6.63 × 10⁻³⁴ Kg.m²/s

Now we will put the values in equation

f = E/h

Kg.m²/s² = j

f = 7.32 × 10⁻¹⁹ Kg.m²/s² / 6.63 × 10⁻³⁴ Kg.m²/s

f = 1.1041 × 10¹⁵ s⁻¹

Wavelength of photon.

E = h.c /λ

λ =  h. c / E

λ = (6.63 × 10⁻³⁴ Kg.m²/s × 3 × 10⁸ m/s) / 7.32 × 10⁻¹⁹ Kg.m²/s²

λ = 19.89 × 10⁻²⁶ / 7.32 × 10⁻¹⁹ m

λ = 2.72  × 10⁻⁷ m
