M/s^2, its an acceleration towards an object
Answer:
The energy of the photon is 1.718×10−26J.
Explanation:
The energy of the photon is
1.718 × 10 − 26J. You use the formula E =, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.
E== = 1.718×10−26J.
Answer:
2.17 mol
Explanation:
Given data:
Number of moles of potassium = 4.34 mol
Moles of hydrogen gas produced at STP = ?
Solution:
Chemical equation:
2K + 2H₂O → 2KOH + H₂
Now we will compare the moles of hydrogen and potassium.
K : H₂
2 : 1
4.34 : 1/2×4.34 = 2.17 mol
So, from 4.34 moles of potassium 2.17 moles of hydrogen are produced at STP.
Answer:The conclusion is less accurate.
