Answer:
Frequency = 1.25 ×10¹³ Hz
Explanation:
Given data:
Wavelength of light = 24.0 μm (2.4 ×10⁻⁵ m)
Frequency = ?
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light /wavelength = frequency
Frequency = 3×10⁸ m /s /2.4 ×10⁻⁵m
Frequency = 1.25 ×10¹³ s⁻¹
s⁻¹ = Hz
Frequency = 1.25 ×10¹³ Hz
Answer:
15 protons
8 electrons in valence shell after accepting 3 electrons
Neutral/no charge before accepting 3 electrons
-3 charge after accepting 3 electrons
Answer:
For H3O concentration you do 10^-pH so if pH is 5 then H3O+ is 10^-5= 1*10^-5 H3O+ ions
For OH is one extra step. First find H3o+ ions using equation above then you have to use that to divide 1*10^-14
So if pH is 5....the H3O+ is 1*10^-5 then OH- = (1*10^-14)/(1*10^-5) = 1*10^-9 OH ions
as far as acid/base pH 0-6 is Acid 8-14 is Base. pH of 7 is neutral. Recheck your work *hint* *hint* water is neutral. Spit is above 7 so is base.
All organisms share certain characteristics of life, for example, all living things are made of cells and they must reproduce to make the next generation. Without these characteristics, there is no life.

The correct option is: CH4 + O2 → CO2 + H2O.
In writing chemical equations, the reactants are usually written to the left of the equation of the reaction while the products are written to the right of the reaction. An arrow pointing in the right direction shows the direction of the reaction. In the question given above, methane and oxygen are the reactants while carbon dioxide and water are the products. The options that states the chemical reaction correctly is option 1.
