Answer:
The answer is B "The lithosphere is characterized by its physical state while the crust is characterized by its composition (mostly oxygen, aluminum, and silicon)
Answer:
Explanation:
We shall apply gas law formula
P₁ V₁ / T₁ = P₂V₂ / T₂
.914 x 350 / ( 273 + 22.7 ) = 1 x 220 / T₂
1.0818 = 220 / T₂
T₂ = 203.36 K
= - 69.64 ⁰ C
Answer:
4 sig figs: 20.18
Explanation:
the smallest amount of digits was 4 in the expression
In chemistry and atomic physics, the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements
Using E=hν where h is Planck's constant and v is the frequency of the photon. In the question above,the wavelenght is given so we can find the frequency of the photon using c=λν. c is a constant =3*10^8 so frequency is equal to
(3*10^8)/0.135*10^-9. Then use ur frequency in the eqn above using h 6.626*10^-34
