(more then one answer) As a form of energy, light has specific properties such as color and brightness. Some properties can only
be seen with special tools. Think about properties of light and how color in white light can be investigated. Which statements are true about light properties and how color in white light can be investigated?
White light can be separated using any glass object.
Light travels in a straight line until it strikes an object.
When white light is separated by a prism, the colors appear in a random order.
The way light reacts when it strikes an object depends on the properties of that object.
When a single-colored light passes through a prism, it becomes white.
As white light passes through a prism , it bends and separates into different colors
As the gas is heated, the particles will begin to move faster. ... Because the gas remains at a constant pressure and volume, the particles cannot spread out so they simply move around the container even faster.
Moles Li = 3.50 g / 6.941 g/mol= 0.504 the ratio between Li and N2 is 6 : 1 moles N2 required = 0.504 /6=0.0840 we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess the ratio between Li and Li3N is 6 : 2 moles Li3N = 0.504 x 2 /6=0.168 mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g
