Answer:
because of catenation of carbon.
Explanation:
Catenation is the binding of an element to its self through covalent bonds to form chain or ring molecules. carbon is able to form continuous links with other carbon atoms which is the reason for the existence of a large number of organic compounds.
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.
Answer:
Atoms are neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
Explanation:
D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
