K + 02 ---> K20
4K + O2 ---> 2K2O
Answer:
1.428 moles
Explanation:
If 0.0714 moles of N2 gas occupies 1.25 L space,
how many moles of N2 have a volume of 25.0 L?
Assume temperature and pressure stayed constant.
we experience it 0.0714 moles: 1.25L space
x moles : 25L of space
to get the x moles, cross multiply
(0.0714 x 25)/1.25
1.785/1.25 = 1.428 moles
Direction medium of the wave move relation to to direction of wave propagation
Answer:
The answer to your question is: number 2 is correct.
Explanation:
Formula
F = m x a
The formula shows that acceleration and mass and inversely proportional, then if the mass increases 3 times, then the acceleration must diminishes 3 times.
1. The object will accelerate the same amount as before because the mass does not affect the object’s acceleration.
This option is incorrect, the acceleration must diminish.
2. The object will accelerate 1/3 as much because if you apply the same net force but increase the mass, the acceleration will decrease. This option is correct, is what i describe above.
3. The object will not accelerate because now it is too heavy.
this option is wrong, because the object will accelerate.
4. The object will accelerate 3 times as much because if you apply the same net force and increase the mass, the acceleration will increase. This option s incorrect, the acceleration will diminish not increase.
