To the top. Common knowledge my dude. Heat always rises to the top.
Answer:
D
Explanation:
I believe it is D. your kinetic energy would be at b. A, the cart would be going at a constant rate, because there is no hill or steep slope.
Answer:
A photons is a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
Explanation:
Light consists of packets of energy (photons) that can only interact with the atoms and molecules of matter by being absorbed or emitted in discrete units. ... Photons carry momentum and energy like particles, but they also have a frequency and a wavelength like a sinusoidal wave. Thanks to photons we know that all quantum particles have both the properties of waves and particles. I hope it helps✌️
Answer:
The answer to your question is: 1.205 x 10²³ atoms of Carbon
Explanation:
Data
Carbons atoms contained in 2.8 g C₂ H₄
MW C₂ H₄ = (12 x 2) + (4 x 1) = 24 + 4 = 28 g
28 g of C₂ H₄ ---------------- 24 g of carbon
2.8 g C₂ H₄ ----------------- x
x = (2.8)(24) / (28)
= 2.4 grams of C
1 mol ------------------- 12 g of Carbon
x ------------------- 2.4 g
x = (2.4x 1) / 12 = 0.2 mol
1 mol ----------------- 6.023 x 10 ²³ atoms
0.2 mol -------------- x
x = (0.2 x 6.023 x 10 ²³) / 1
= 1.205 x 10²³ atoms
