Answer:
wavelength = 0.534×10⁻¹⁶ m
Explanation:
Given data:
Frequency of wave = 5.62 ×10²⁴ Hz
Wavelength = ?
Solution:
Speed of photon = wavelength × frequency
wavelength = speed of photon / frequency
Now we will put the values in formula:
wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ Hz
Hz = s⁻¹
wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ s⁻¹
wavelength = 0.534×10⁻¹⁶ m
Answer:
B
Explanation:
it depends if the weather was cold but ummm they warm and cold air would mix and turn story and watch out tornadoes could also happen
Either NaI or INa are acceptable formulae for sodium iodide, which is indeed a binary ionic compound. So, the correct answer would be B.
Among the choices above, I think the statement that best describes an intensive property of matter is letter B which is " It depends on how a substance was formed." <span>Intensive properties are those property which does not depend upon the amount of substance present in the system. Such as refractive-index, density etc </span>
Answer:
The answer to your question is HCl + NaOH ⇒ NaCl + H₂O
Explanation:
Data
Double displacement reaction
Balanced chemical reaction
HCl + NaOH ⇒ NaCl + H₂O
Reactants Elements Products
1 Chlorine (Cl) 1
1 Sodium (Na) 1
2 Hydrogen (H) 2
1 Oxygen (0) 1
As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.
