waves in certain wavelength ranges interact with water

Introductory Chemistry 5
Is each chemical equation correctly balanced? If not, correct it. (a) \(R b(s)+\mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{RbOH}(a q)+\mathrm{H}_{2}(g)\) (b) \(2 \mathrm{~N}_{2} \mathrm{H}_{4}(g)+\mathrm{N}_{2} \mathrm{O}_{4}(g) \rightarrow 3 \mathrm{~N}_{2}(g)+4 \mathrm{H}_{2}

An iron bar weighed 664 g. After the bar had been standing in moist air for a month, exactly one-eighth of the iron turned to rust \(\left(\mathrm{Fe}_{2} \mathrm{O}_{3}\right)\). Calculate the final mass of the iron bar and rust.

Biology 8
Dmw Lewis structures for each hypothetical molecule shown below, using the correct number of valence electrons for each atom. Determine which molecule makes sense because each atom has a complete valence shell and each bond has the correct number of electrons. Explain what makes the other molecules n

Physics: Principles with Applications 7
If 720-nm and 660-nm light passes through two slits 0.62 mm apart, how far apart are the second-order fringes for these two wavelengths on a screen 1.0 m away?

Introductory Chemistry: A Foundation 9
The boiling of water is a a. physical change because the water disappears. b. physical change because the gaseous water is chemically the same as the liquid. c. chemical change because heat is needed for the process to occur. d. chemical change because hydrogen and oxygen gases are formed from water.

Biochemistry 9
It is possible for the codons for a single amino acid to have the first two bases in common and to differ in the third base. Why is this experimental observation consistent with the concept of wobble?

The mass of a spacecraft is about 480 kg. An engine designed to increase the speed of the spacecraft while in outer space provides 0.09-N thrust at maximum power. By how much does the engine cause the crafts speed to change in 1 week of running at maximum power? Describe any assumptions you made.
