Answer:
The Answer is B. Destructive Interference
Explanation:
Answer:
Explanation:
Arrhenius defined an acid as a substance that interacts with water to produce excess hydrogen ions in aqueous solution.
A base is a substance which interacts with water to yield excess hydroxide ions, in an aqueous solution according to Arrhenius.
Bronsted-Lowry theory defined an acid as a proton donor while a base is a proton acceptor.
Answer:
See explanation
Explanation:
From the information provided;
P1 = initial pressure = 758.0 mmHg
T1 = Initial temperature = 32.7°C + 273 = 305.7 K
V1 = Initial volume?
P2 = Final pressure = 364.2 mmHg
V2 = Final volume = 425 L
T2= Final Temperature = 3.10°C + 273 = 276.1 K
P1V1/T1 = P2V2/T2
P1V1T2 =P2V2T1
V1 = P2V2T1/P1T2
V1 = 364.2 * 425 * 305.7/758.0 * 276.1
V1 = 226. 18 L
B) Total pressure = 100.0 kPa
Pressure of Helium = 83.1 kPa
Pressure of carbon dioxide = 0.1000 kPa
Pressure of oxygen ?
From Dalton's law of partial pressures;
PT = P1 + P2 +P3 +.........
Hence;
Poxygen = 100.0 kPa - (83.1 kPa + 0.1000 kPa)
Poxygen = 16.8 kPa
Answer:
Explanation:
%mass of glucose =( mass of gucose /mass of solution )x100%
= 163 / (755+ 163 )
= 17.76 %
Answer:
Heyo
Explanation:
Humus is often used by to fertilize the soil. Aside from adding nutrients, it also loosens the texture of the soil. With a freer texture, air and water can more easily penetrate, and oxygen can reach the plant’s root system faster. Some experts also believe it has the ability to prevent plants from getting hit by the disease.
hope this helps!
