- By changing three atom bond angle , we can change molecular polarity. if bond angle is 120° and all atom has same electronegativity, the resultant polarity ( dipole moment ) become zero. we can change bond anngle either less than or greater than 120°, but not exactly 120
- Replacing one or more atom with different atoms having electro negativity values also make molecular poles.
- By placing molecules under external electric field or magnetic field also causes to the molecule.
The different is that the galvanic cell converts chemical energy into the electrical energy and the electrolytic cell coverts electrical energy into chemical energy
Answer:
were learning about this right now can you help me with the wuestion 8th grade sucks.
Explanation:
Molar mass KI = 166.0028 g/mol and Pbl₂ = 461.0089 g/mol
<span>2 Kl + Pb(NO</span>₃<span>)</span>₂<span> ------> 2 KNO</span>₃<span> + Pbl</span>₂<span>
</span>
2 x 166.0028 g ---------> 461.0089 g
? g KI -------------> 1.2 g
Mass KI = 1.2 x 2 x 166.0028 / 461.0089
Mass KI = 398.40672 / 461.0089
Mass KI = 0.86 g
Answer B
hope this helps!
Answer:
20 J
Explanation:
The formula for work (w) done is
w = f × d
w = 10 N × 2 m = 20 N·m = 20 J
The work done is 20 J.
