Answer: I belive the answer is A
Explanation:
Osmotic pressure is calculated by the product of the concentration in molarity, the temperature, the vant Hoff factor (3 for CaCl2 and 1 for sucrose) and R, universal gas constant. At the same temperature, the osmotic pressures of both solutions are equal.
π = CRTi
For CaCl2,
π = (1)RT(3) = 3RT
For sucrose,
π = (3)RT(1) = 3RT
Answer:
D: lose an electron
Explanation:
when an atom loses an electron it's positively charged and when it gain an electron it is negatively charged
Wind affects pollution because it moves it, the wind carries the pollution and move it somewhere else
