Answer:
2H2O2 --> O2 + 2H2O
It is decomposition of hydrogen peroxide into oxygen.
It can also be described a reaction showing how H2O2 acts as a reducing agent
H2O2(aq) ---------> O2(g) + 2H^+ (aq) + 2e E = + 1.77 V
2h2 O2 2h2o
Answer:
Air Conditioner!
Explanation:
Puts out cool air, removing the hot air!!
(Hope this made somone laugh)
Answer:
if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity
The greater the force that is applied to an object of a given mass, the more the object will accelerate
Explanation:
For example, doubling the mass of an object results in only half as much acceleration for the same amount of force
Answer:
D
Explanation:
1.) First convert to molar mass
18.1*1/231.533*18.01528=
Answer:
Solubility of gases in water: a. decreases with increasing pressure above solution. b. increases with increasing pressure above solution.c. is independent of pressure above solution.d. Gases are not soluble in water.e. none of the above
The answer to the question is option B (increases with increasing pressure above solution).
Explanation:
Solubility is the chemical property of a solute to dissolve into a solvent. The solubility which is the characteristic property of a specific solute–solvent combination of a substance fundamentally depends on the solvent used, as well as temperature and pressure.
Concentration of molecules in the gas phase increases with increasing pressure. At low pressure, a gas has a low solubility, while at at high pressure, a gas has a high solubility. The rate at which gas molecules collide with the surface of the liquid and dissolve depends on the pressure of the gas in relation to the number of molecules of gas per unit volume. The solubility of gases in water, makes an increase in pressure result in a proportional increase in solubility, whereas a decrease in pressure decreases solubility.
This can be expressed in the equation: C= k x Pgas
where C= solubility of gas in solvent, k= proportionality constant and Pgas = partial pressure of the gas above the solution.
