Answer:
1.- Chemical change
2.- Because the atoms in the image are tranformed into a new molecule
3.- Yes, it does
4.- Due to the amount of atoms are the same both in products and reagents
Explanation:
Answer:
N₂ + 3H₂ → 2NH₃
Explanation:
Chemical equation:
N₂ + H₂ → NH₃
Balanced chemical equation:
N₂ + 3H₂ → 2NH₃
Step 1:
N₂ + H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 2 H = 3
Step 2:
N₂ + 3H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 6 H = 3
Step 3:
N₂ + 3H₂ → 2NH₃
left hand side: Right hand side
N = 2 N = 2
H = 6 H = 6
"B. The radiant sun.
The Sun, like all stars, is a huge plasma ball of very high density and temperature. It consists almost entirely of hydrogen, with a small component of helium and all other elements in smaller proportions.
Although the plasma in the deep interior of the Sun has a chaotic movement, towards its surface and on it the movements of the plasma are already more ordered. Below the surface of the Sun the plasma circulates up and down, forming cells called convection, and on the surface and already in its atmosphere the movements of the plasma are strongly controlled by local magnetic fields of varying intensity and varied structure."
Answer:
high, low
Explanation:
In simple diffusion, molecules move from an area of high concentration to an area of low concentration.
