Answer:
E= 3.829 x 10-16 J
Explanation:
Data Given
Frequency= 5.78 x 10^17 Hz
Energy in joules = ?
Solution:
Formula used to calculate Energy
E= hv…………….. (1)
Where E is Energy
h is Planks Constant = 6.626 x 10–34 J s
v is frequency
The given frequency is in Hz (Hertz)
Hz is equal to s-1 (per second)
1 hertz = 1 /second
Putting the values in Equation 1
E= (6.626 x 10–34 J s) (5.78 x 1017 s-1)
E= 3.829 x 10-16 J
Answer:
0.188mol
Explanation:
Using the formula as follows:
mole = mass/molar mass
Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)
= 3 + 55 + 64
= 122g/mol
Mass of H3MnO4 is given as 22.912 g
Hence;
moles = 22.912 ÷ 122
number of moles = 0.188mol
Answer:
Carbon Tetrachloride
Explanation:
1 Carbon atom, 4 chlorine atoms (hence "tetra" prefix)
Answer:
<h2>The gas pressure will remain the same until the number particles remain in the range of multiple of avagadro number.</h2>
Explanation:
It will remain same until the avagadro number is achieved as the gass less than avagadro number (1 mole) will occupy same volume as the the multiple of avagadro number ( mole).
If gas is less than 1 mole it will occupy same volume as that of 1 mole.... If the number of particles are increased than the 1 mole. The gas occupy more volume consequently the pressure will be increased.
Kindly mark it branliest if the answer is little bit satisfying.
D. I hope you have a good morning
