The answer is pressurized liquids
Answer:
frequency=?
Explanation:
wavelength=4.6x10^6m
speed=3x10^8ms-1
frequency=[3x10^8]/[4.6x10^6]
frequency=65.2s-1
Answer: Formula: Mass = (Volume)(Density)
Iron Density = 7.87 g/cm^3
Volume of Iron = 55.2 cm^3
Mass=(V)(D)
Mass= (55.2 cm^3) x (7.87 g/cm^3)
Mass= 434,42 g
Explanation:
Since O almost always has a charge of -2, the oxygen atoms have an overall charge of -8 (-2*4)
Since K has a charge of +1, that brings the overall charge to -7 (-8+1)
Then, in order for the overall charge to be 0, Mn would have to have a change of +7 (-7+7=0)
Hope this helps
<u>Answer:</u> The equilibrium constant for the given reaction is 4.224
<u>Explanation:</u>
We are given:
Equilibrium concentration of water = 0.250 M
Equilibrium concentration of hydrogen gas = 0.330 M
Equilibrium concentration of oxygen gas = 0.800 M
For the given chemical reaction:
The expression of for above reaction follows:
Putting values in above expression, we get:
Hence, the equilibrium constant for the given reaction is 4.224
