Answer:
The rate at which sulfur dioxide is being produced is 0.90 kg/s.
Explanation:
Volume of oxygen gas consumed in second ,V= 994 L
Pressure of the gas = p
Temperature of the gas = T = 170°C= 170 + 273 K=443 K
Moles of oxygen gas consumed in a second = n
( ideapl gas equation)
n = 21.044 mole
Moles of dioxygen gas consumed per second = 21.044 mol
(Claus process)
According to reaction, 3 moles of dioxygen gives 2 moles of sulfur dioxide gas.Then 21.044 moles of dioxygen will give;
of sulfur dioxide
Mass of 14.029 moles of sulfur dioxide gas;
14.029 mol × 64 g/mol = 897.86 g
897.86 g = 0.89786 kg ≈ 0.90 kg
Mass of sulfur dioxide produced per second = 0.90 kg
The rate at which sulfur dioxide is being produced is 0.90 kg/s.
C - single replacement reaction
Answer:
A mixture of solid particles and gases in the air.
Explanation:
Air pollution is a mixture of solid particles and gases in the air. car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Answer:
B. A+ B → AB
Explanation:
general form of a synthesis reaction
<span>Heat released by the water: mass * specific heat * ΔT
Heat released by the water = 55.9 g * 1 cal / (°C g) * (99.2 - 96.9 )°C
Heat absorbed by the zinc metal = mass * specifi heat * ΔT
Heat absorbed by the zinc metal = 23.9 g * Cp * (96.9 - 21.1) °C
Heat absorbed by zinc metal = heat released by water
=> 23.9 * Cp * 75.8 = 55.9 * 1 * 2.3
=> Cp = 128.57 / 1811.62 = 0.0071 cal / (g°C)
Answer: 0.0071 cal / (g°C)
