Answer:
λ = 0.5×10⁻⁵ m
E = 39.78×10⁻²¹ J
The given radiation is gamma ray.
Explanation:
Given data:
Frequency of radiation = 6.0 ×10¹³ Hz
Wavelength of radiation = ?
Type of radiation = ?
Energy of radiation = ?
Solution:
Formula:
speed of light = wavelength × frequency
3 ×10⁸ m/s = λ × 6.0 ×10¹³ Hz
Hz = s⁻¹
λ = 3 ×10⁸ m/s / 6.0 ×10¹³ s⁻¹
λ = 0.5×10⁻⁵ m
Energy of radiation:
E = hf
h = planck's constant
f = frequency
E = 6.63×10⁻³⁴ j.s × 6.0 ×10¹³ s⁻¹
E = 39.78×10⁻²¹ J
The given radiation is gamma ray.
Answer:
Explanation:
When looking at a chemical reaction, the substance present before the reaction takes place are called the (5)
REACTANT
and the substance produced after the reaction are the (6).
PRODUCT
know through the Law of Conservation of (7)
MATTER
that nothing is created or destroyed. This is reflected in a (8
BALANCED
chemical equation, where the NUMBER OF atoms of each element on each side of the arrow is (9)-
equal
or the same.
REMEMBER: WHEN BALANCING EQUATIONS YOU CANNOT CHANGE THE SUBSCRIPTS OF THE COMPOUNDS, YOU CAN ONLY SHOW BY THE COEFFICIENTS HOW MANY MOLECULES YOU HAVE!
3 Common States of Matter:
1. Solid - particles are motionless and stick together very closely.
2. Liquid - particles are moving slowly without pattern.
3. Gas - Particles are moving rapidly again without pattern.
Answer:
A. 1350
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
34% I believe
