This is true because the water would have gravitational potential energy that is caused by the water being held back by the dam and the water wanting to flow down.
This can be converted into kinetic energy when given the chance to, such as having a turbine on the dam.
Hope this helps! :)
Answer:
<em><u>0.27 g</u></em>
Explanation:
The reaction equation:
→
106g of Na2CO3 - 1 mole
0.5g of Na2CO3 = 0.5 ÷ 106
= 0.0047 moles.
1 mole of NaCl - 58.5
⇒ 0.0047 moles = 0.0047 × 58.5
= 0.27g.
The fumes of acetic acid go to the floor instead of ceiling.
The reason behind the answer is that the density of acetic acid fumes is higher than the density of air (almost twice) that is equal to only 1 .
Thus, the fumes of acetic acid go to the floor.
