Answer:
it breaks down things and cools things down
Explanation:
Answer:
f = 6 × 10^15 Hz in the ULTRAVIOLET (UV) region
Explanation:
Using λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
According to this question, λ = 5.00 x 10^-6 cm
= 5.00 x 10^-8 m
λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 5.00 x 10^-8
f = 0.6 × 10^(8+8)
f = 0.6 × 10^16
f = 6 × 10^15 Hz
In the electromagnetic spectrum (EM), a frequency of 10^15 is found in the ULTRAVIOLET region. This means that this radiation with a wavelength of 5.00 x 10^-6 cm and frequency of 6 × 10^15 Hz is in the ULTRAVIOLET region of the EM spectrum.
Answer: The diagrams show gases that are stored in two separate but similar containers. If both gases are at the same temperature, which one has the greater pressure? Gas 2 because it has more particles that are colliding.
Explanation:
Answer:The value of equilibrium constant is .
Explanation:
Expression of an equilibrium constant is given as:
The value of equilibrium constant is .
1, 4, 1, 2, 1
Explanation:
We have the following chemical reaction:
MnO₂ + HCl → MnCl₂ + H₂O + Cl₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
MnO₂ + 4 HCl → MnCl₂ + 2 H₂O + Cl₂
