99.6 mg= .0996 g
.0996g x (1mol/125.05g) x (1 mol SO3/1 mol Na2SO2) x (6.02 x 10^22/1mol SO3) = 4.79 x 10^19 SO32- ions
Plasma is one of the four states of matter, others being gas, liquid and solid. Thermal plasma is a kind of plasma that is in thermal equilibrium and can tolerate high temperatures unlike cold plasma.These are produced in plasma torches discharged at high temperatures.
Answer:
The titration process has quite a few real-world uses, including key roles in the food industry and medical community. The titration process is essentially an analytical technique, as it is used to determine a chemical or physical property of a chemical substance, element, or mixture (such as food). Specifically in the food industry, it is used to allow food manufactuers to determine the quantity of a reactant in a sample. To provide an example, it can be used to find the specific amount of stuff that is usually labeled on the nutrition label, such as sugar, salt, protein, calcium, vitamin C, etc. As for the medical world, pharamcists typically use this process to get the proper mix when compounding medicines. It is used to get the necessary proportions in intravenous drips.
Answer:
77.6 g are the mass of silver
Explanation:
This is a calorimetry problem, All the heat released by the silver was gained by the water, so the T° has increased.
Q = m . C . ΔT
mass from silver . 0.056 cal/g°C . (26.2°C - 58.5°C) = 100 g . 1 cal/g°C (26.2°C - 24.8°C)
mass from silver . 0.056 cal/g°C .-32.3°C = 100 g . 1 cal/g°C . 1.4°C
mass from silver . -1.8032 cal/g = 140 cal
mass from silver = 140 cal / 1.8032 g/cal
mass from silver = 77.6 g
