How many grams of ko2 are needed to form 6.5 g of o2?
NNADVOKAT [17]
Decomposition of a potassium superoxide  happens according to the scheme:

4KO₂(s) + 2H₂O(l) → 4KOH(aq) + 3O₂(g)

m(K₂O)=4M(K₂O)m(O₂)/{3M(O₂)}

m(K₂O)=4×71.1×6.5/{3×32.0}≈19.3 g

Four moles of Argon gas are at a pressure of 1.90 atm, and the temperature is 50 degrees C. What is the volume of the gas?
soldier1979 [14.2K]
N = 4 moles of Ar2, P = 1.90 atm, V = ?
T = 50C = 273 + 50K = 323K
PV = nRT --> V = nRT/P
V = (4)(.0821)(323)/1.90
V = 106.07/ 1.9
V = 55.8 L

What is the wavelength in meters of a proton (mass = 1.673 x 10-24 g) that has been accelerated to 5% of the speed of light?
Molodets [167]

Explanation:

since it has been accelerated to 5℅ of the sleec of light then

v= 5/100 × (3× 10^8)

after getting velocity you'll substitute the values in the formula

de Broglie wavelength= h/mv

don't forget to change the grams in mass to kg

The virial equation of state is not recommended to be used for polar compounds (asymmetrical compounds with non- zero dipole mom
Pepsi [2]

Answer:

True

Explanation:

*For polar and associated substances, methods based on four should be used  four or more parameters, like analytical equation of state

*The term "analytical equation of state" implies that the function

It contains powers of v not greater than four.

*Most expressions are of the cubic type and are grouped into

the so-called cubic equations of state.

*Cubic EoS calls are very popular in simulation of

processes due to its robustness and its simple extension to mixtures.

*They are based on the van der Waals state equation of more than

100 years.
