Answer:
A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes.The second change of phase is boiling, as the temperature stays the same during the transition to gas.
Explanation:
Minerals form by erosion of rocks.The erosion process includes water and other rocks rubbing against other rocks.
69,57% + 30,43% = 100%
100% ----------- 92,02g
69,57% oxygen ----- x
x = 64,004 ≈ 64,00g oxygen
100% ---------- 92,02g
30,43% nitrogen ----x
x = 27,99 ≈ 28g nitrogen
Mass of oxygen = 16g
Mass of nitrogen = 14g
moles of oxygen = 64g : 16g = 4
moless of oxygen = 28g : 14g = 2
N : O
4 : 2 ||:2
2 : 1
empirical formulas = N₄O₂
molecular formulas = N₂O
N₂ + ¹/₂O₂ ---> N2O
Air flows counterclockwise and inward for all low pressure systems in the Northern Hemisphere and clockwise and inward in the Southern Hemisphere. And high pressure systems flow clockwise and outward in the Northern Hemisphere and in the Southern Hemisphere they flow counterclockwise and outward.
Answer:
C
Explanation:
This is the only option that could produce an objective answer through experimentation or studies. The other options can be answered subjectively and are opinion based. They could not be answered scientifically.
