The answer is A. Nickel, zinc, and iron
Explanation:
Answer:
2.2 × 10⁻⁴ m
Explanation:
Step 1: Given and required data
- Energy of the wave (E): 9.2 × 10⁻²² J
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Calculate the wavelength (λ) of the wave
We will use the following expression.
E = h × c/λ
λ = h × c/E
λ = 6.63 × 10⁻³⁴ J.s × 3.00 × 10⁸ m/s/9.2 × 10⁻²² J
λ = 2.2 × 10⁻⁴ m
Answer:
22.5
Explanation:
all you have to do is take the number of moles of al and multiply them by sulfuric acids mole ratio as given in the equation (3), then divide by aluminums mole ratio number (2). then you will have moles of sulfuric acid.
*note: this only works if you are going moles to moles, if you are converting to anything else, this will NOT work*
if you have any questions leave them in the comments and i will try to answer them, if this helped, pls give a brainly
