C.Lightweight and durable.
Answer:
Barium precipitation : in this method we will add Barium chloride to the wastewater to precipitate Barium sulphate precipitate from the waste water
Explanation:
The measures that can be taken for the recovery of sulfates and other contaminants from wastewater includes : ion exchange, precipitation and Reverse osmosis. of all these measures i will discuss precipitation
Precipitation measures can be performed using different methodologies the methodology that i will discuss is :
Barium precipitation : in this method we will add Barium chloride to the wastewater to precipitate Barium sulphate precipitate from the waste water
The sulphate contained in the wastewater can be reduced to as low as 200 mg/l using this method
Temperature : the increase in temperature of the waste water will cause the reduction in formation of sulphate in the waste water
PH changes : for the precipitation of sulphate to be effective the required PH level is 4.5
Answer:
1.10 g H2
Explanation:
I took the test and got the answer correct
Answer: Nothing
Explanation:
Cobalt-60 emits γ radiation and is used in many applications including cancer treatment: There is no change in mass number or atomic number during the emission of a γ ray unless the γ emission accompanies one of the other modes of decay.
Rutherford postulated the existence of some neutral particle having mass similar to proton but there was no direct experimental evidence. Several theories and experimental observations eventually led the discovery of neutron.
