If the speed of light is 3.00 x 108 m/s, how many minutes will it take for sunlight to reach the Earth if the distance between the Sun and the Earth is 92.96 million miles? (There are 2.54 cm in 1 inch and 5280 feet in 1 mile.)

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?

What are the first three quantum numbers for the electrons located in subshell 2s?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
