Answer:
.08 L or 80 ml
Explanation:
Use the equation V/t = V/t.
.04L / 150K = V / 300K
.04 / 150 * 300 = V
.08 L or 80 ml
Answer:
Option b) polyatomic ions
Explanation:
Polyatomic ions are ions consisting of two or more atoms.
From the question given above, we can see that each ions consist of more than one atom as shown below:
Ions >>>>>> Number of atom present
NH4+ >>>>> 2
CO32− >>>> 2
PO43− >>>> 2
Thus, we can say that the above ions are polyatomic ions.
1. <em>Describe</em>
Frequency (f) and wavelength (λ) are inversely related.
f ∝ 1/λ
As one goes up, the other goes down and vice versa.
2. <em>Infer
</em>
The frequency of infrared light is less than that of red light, so infra could mean something like less than or below or beneath.
Ultrahigh frequencies are extremely high compared with those of visible light. Ultrasound has frequencies that are far beyond what we can hear. An ultracentrifuge goes at extremely high speed, and an ultramicroscope can “see” tiny structures. Ultra could probably mean something like extremely or far beyond.
3. <em>Analyze
</em>
Energy is directly proportional to frequency (E ∝ f).
Frequency is inversely proportional to wavelength (f ∝ 1/λ).
Energy is inversely proportional to wavelength (E ∝ 1/λ).
Hi! Chemistry is complicated, right?
A hydroxyl group is a group that consists of
oxygen and hydrogen bonds. When they combine, ethanol may be released.
I hope I helped!
