In Florida, more than 20,000 crashes are alcohol related
Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
Matter can be classified according to physical and chemical properties. Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. Extensive properties depend on the amount of material and include mass and volume.
The question is incomplete, the complete question is shown in the image attached.
Answer:
Cation
Explanation:
In a polar reaction mechanism, a specie must give out electrons and another specie must accept those electrons.
The specie that gives out electrons becomes electron deficient and positively charged so we refer to such a specie as a cation.
Hence, the specie that looses electrons becomes a cation.
Answer:
5.13×¹⁴ Hz
Explanation:
The following data were obtained from the question:
Energy (E) = 3.4×10¯¹⁹J
Frequency (f) =?
Energy and frequency are related by the following formula:
E = hf
Where:
E is the energy.
h is the Planck's constant.
f is the frequency.
Thus, we can obtain the frequency of the photon by using the above formula as illustrated below:
Energy (E) = 3.4×10¯¹⁹J
Planck's constant (h) = 6.63×10¯³⁴ Js
Frequency (f) =?
E = hf
3.4×10¯¹⁹ = 6.63×10¯³⁴ × f
Divide both side by 6.63×10¯³⁴
f = 3.4×10¯¹⁹ / 6.63×10¯³⁴
F = 5.13×¹⁴ Hz
Thus, the frequency of the photon is 5.13×¹⁴ Hz.
