- The distance between two adjacent peaks on a wave is called the wavelength.(a) The wavelength of a beam of ultraviolet light is 247 nano-meters (nm). What is its wavelength in meters?(b) The wavelength of a beam of red light is 6760 pm. What is its wavelength in angstroms (Å)?arrow_forwardThe radius of an atom of krypton (Kr) is about 1.9 Å. (a) Express this distance in nanometers (nm). 0.19 ✓ nm Express this distance in picometers (pm). 190 pm (b) How many krypton (Kr) atoms would have to be lined up to span 1.0 mm? 2.6 X atoms (c) If the atom is assumed to be a sphere, what is the volume in cm³ of a single krypton (Kr) atom? 2.87 x cm³arrow_forward4) ½N2(g) + 02(g)= NO2(g) Kc = 1.04 x 10° N2(g) + 202(g) = N204(g) Kc = 7.42 x 10-18 Calculate Kc for each of the following.

- Calculate these masses.(a) What is the mass of 6.00 cm3 of mercury, density = 13.5939 g/cm3?(b) What is the mass of 25.0 mL octane, density = 0.702 g/cm3?arrow_forward7. State whether each of the following represents a chemical change or merely a physical change:(a) A few grams of sucrose (table sugar) are placed in a small beaker of deionized water; the sugar crystals “disappear,” and the liquid in the beaker remains clear and colorless.(b) A copper statue, over time, turns green.(c) When a teaspoon of baking soda (sodium bicarbonate) is placed into a few ounces of vinegar (acetic acid), volumes of bubbles (effervescence) are produced.arrow_forward1) Perform the indicated mathematical operations. State the uncertainty of the final answer as ± 1-digit variation in the least significant digit. (remember that the last significant digit's place holder is the most uncertain digit!) 7.700 x 2.1 = uncertainty: 2.132 + 17 + 4.04 = uncertainty: 27000 + 500 = uncertainty: 30.0 x 50.0 = uncertainty: (9.6 × 107)(1.24 × 10³)_ uncertainty: 1.897 x 102arrow_forward
