Let me know how you did, good luck! :D
Answer: uranium
Explanation: It’s hard to find when mining and is required for nuclear fission
In order to determine the frequency, we may use Planck's equation:
Energy = Planck's constant * frequency
Rearranging and substituting the values,
frequency = (1.8 x 10⁻¹⁵) / (6.63 x 10⁻³⁴)
f = 2.71 x 10¹⁸ Hz
The frequency of the light is 2.7 x 10¹⁸ Hz
Answer:
The fertilizer ammonium sulfate, (NH4)2SO4, is prepared by the reaction of ammonia, NH3, with sulfuric acid: 2 NH3 (g) + H2SO4 (aq) (NH4)2SO4 (aq)
How many moles of ammonium sulfate are produced if 1.50 moles of ammonia react completely at STP? Answer: The balanced equation indicates that 2 moles of NH3 react to produce 1 mole of (NH4)2SO4.
1.50 moles NH3 x 1 mol (NH4)2SO4 = 0.750 moles (NH4)2SO4
Explanation:
65 Grams is the mass of the beaker because you just take the mass of Water + Beaker and take the water away now you have the mass of the beaker
