The frequency of radiation : 1.2 x 10¹⁵ Hz
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
<h3>f = c / λ
</h3>
c = speed of light
= 3.10⁸ m/s
λ = wavelength
Wavelength-λ is 2.51 x 10⁻⁷m
The frequency :
Answer: 1820 mL (to 3 sf)
Explanation:
The atomic mass of aluminum is 26.9815385 g/mol, so 4.10 g of aluminum is equal to 4.10/26.9815385 = 0.15195575300497 moles of Al.
From the coefficients of the equation, we know that for every 2 moles of aluminum consumed, 6 moles of HCl are consumed.
So, this means we need 0.15195575300497(6/2) = 0.45586725901491 moles of HCl.
Substituting into the molarity formula,
- 0.250 = 0.45586725901491/(liters of HCl)
- liters of HCl = 0.45586725901491/0.250
- liters of HCl = 1.8234690360596 L = 1820 mL (to 3 sf)
If you can provide the reaction you are looking at, then we can provide a more satisfactory answer.
If the forward reaction is exothermic, then reducing the temperature where the reaction occurs will shift the equilibrium towards the right. This is because exothermic reactions release heat, and this will counteract the change as stated in Le Chatelier's Principle.
If the forward reaction is endothermic, then reducing the temperature will shift to the left. This occurs as the backward reaction is the exothermic reaction, and by Le Chatelier's Principle, the reaction will favor the reaction that produces more in to counter a reduction in temperature, in this case the backward direction reaction.
<u>Answer:</u> The correct answer to this problem is 2.
<u>Explanation:</u>
We are given a mathematical problem, which is:
1 + 1 = ?
To solve this, we use the mathematical operator known as addition. In this, we add two numbers and the resulting value is the answer to the problem.
By adding 1 and 1, we get:
Thus, the correct answer to this problem is 2.
