Answer:
1.38 g/ml
Explanation:
density is equal to mass divided by volume so divide 138 by 100 and your answer would be 1.38
hope it helped

Answer and Explanation:
The equation that depicts oxidation of neutral atom A is shown below:
![\rightarrow A^+ + e^-](https://tex.z-dn.net/?f=%5Crightarrow%20A%5E%2B%20%2B%20e%5E-)
This is because one species is losing electrons due to oxidation. The species possesses positively charged after losing electrons, the magnitude of which is proportional to the number of electrons lost.
The net charge will be equivalent on both sides of the equation, too.
Therefore all other options are not correct
The equation that depicts the decline of neutral atom X is
![X + e^- \rightarrow X^-](https://tex.z-dn.net/?f=X%20%2B%20e%5E-%20%20%5Crightarrow%20%20X%5E-)
It is how a cell gains electrons by reduction. The species obtains a negative charge upon possessing electrons, whose magnitude is equivalent to the amount of electrons gained.
The net charge will be equivalent on both sides of the equation, too.
Therefore all other options are not correct
Answer:
v = 450 m/s
Explanation:
Given data:
Frequency = 75 Hz
Wavelength = 6 m
Velocity = ?
Solution:
Velocity is the product of frequency and wavelength.
v = f × λ
v = 75 Hz × 6 m
Hz = s⁻¹
v = 75 s⁻¹ × 6 m
v = 450 m/s
