Lab Safety Rule #3 says to always add acids or bases to the solvent and NEVER the other way around true or false?

Chemistry
1 answer:
VladimirAG [237]3 years ago
7 0

Answer:

true

Explanation:

<em>The standard laboratory rule is to always add acids or bases to solvent and not the other way round.</em>

The dissolution of concentrated acids/bases in solvents (water) generates heat energy. Thus, if the solvent is added to them, a layer of hot weak acid or base will be formed and this will boil and spray around, causing an explosion.

On the other hand, if acid/base is added to solvents, they flow into the solvents and get diluted immediately without any boiling taking place. Hence, it is safe to add acid/base to solvents and not the other way round.

An ant carries a morsel of food 4.26 meters along a straight path to his nest. he then turns around and follows the path back to
SVEN [57.7K]
<span>Answer: 0.00 meters

  Solution:

    Step 1: Define displacement DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."

  Step 2: Understand the question

 Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).

  Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).

   Step 3: Analyze the question

  What is the distance between where the ant originally started and where it ended its journey?

  The ant started and ended its journey in the same place.

 While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)

  Therefore, the answer is 0.00 meters</span>
