Fiber optic cable is available in 12 km lengths. How long will it take for a signal to travel that distance assuming that the speed of light in the cable is the same as in a vacuum?
A sample of 0.0020 mole of HCl is dissolved in water to make a 2000-mL solution. Calculate the molarity of the HCl solution, the [H3O+], and the pH. For a strong acid such as HCI, the [H3O+] is the same as the molarity of the HCl solution.
When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a prefix with the unit.
The hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 295 mL measured at 1.00 atm. Calculate the number of grams of sodium used in the reaction. (Vapor pressure of water at 25°C = 0.0313 atm.)
If solar radiation is 1200 W/m^2 , how many photons strike the leaf every second? Assume three significant figures and an average wavelength of 504 nm for solar radiation. A green leaf has a surface area of 2.75 cm^2 .
If all of the electron groups around a single central atom are bonding, and the same outer atom is bonded to the central atom in each case, is the molecule polar, nonpolar, or does it depend on the identity of the outer atom?
A sample of He gas (V = 3.0 L) at 5.6 atm and 25 °C was combined with 4.5 L of Ne gas at 3.6 atm and 25 °C in a 9.0 L flask (which was initially evacuated).
How much H2O is produced when 20000 g of C2H2 burns completely? Answer in units of grams
How many kilograms of magnesium can be obtained from 5.96 km^3 of seawater if the initial Mg^2+ concentration is .19% by mass. Remember the density of seawater is 1.04 g/ml
Draw resonance contributors for the following: indicate major and minor contributors to hybrid
A gaseous reaction occurs at a constant pressure of 45.0 and releases 61.0 of heat. Before the reaction, the volume of the system was 9.00 . After the reaction, the volume of the system was 3.00 .
How many moles of ammonia are produced when 20 moles of hydrogen react with 40 moles of nitrogen
4HCl(aq) + O2(g)--->2H2O(l) + 2Cl2(g) how many molecules of Cl2 would be formed from the reaction mixture that produces the greatest amount of particles?
