Answer:
C. both
Explanation:
The particle theory and wave theory are both used today.
The particle theory tells us that light is a particle or photon. The wave theory tells us that light travels in waves.
HETEROTROPHS
Explanation:
Autotrophs are any organisms that are capable of producing their own food. For most, this is achieved by using light energy, water and carbon dioxide. Heterotrophs cannot produce they have to absorb.
Answer:
its satellite tracking
Explanation:
i had this question before
Answer:
The osmotic pressure is 7.63 atm
Explanation:
We apply the osmotic pressure formula to solve this problem:
π = M . R . T . i
CaCl₂ → Ca²⁺ + 2Cl⁻ (i = 3)
The i refers to the Van't Hoff factor which refers to the amount of ions dissolved.
T is the Absolute T°, for this case 310K
R is the universal constant gase → 0.082 L.atm/mol.K
M is the molarity → 0.1 mol/L
We replace the values → π = 0.1 mol/L . 0.082 L.atm/mol.K . 310K . 3
π = 7.63 atm
