4) When carbon disulfide burns in the presence of oxygen, sulfur dioxide and carbon
dioxide are produced according to the following equation:
CS2 + 3 O2 → CO2 + 2 SO2

a) What is the percent yield of sulfur dioxide if the burning of 25.0 g of carbon
disulfide produces 40.5 g of sulfur dioxide?

A100-watt light bulb radiates energy at a rate of 100 j/s. (the watt, a unit of power or energy over time, is defined as 1 j/s.) if all of the light emitted has a wavelength of 525 nm , how many photons are emitted per second?

Which statement best explains the relationship between an area is geography and the temperature of its surface water

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
