Syringe tips and titrant solution in a container, unused solid reagent in the manufacturer's container and broken flask in the cardboard box.
Syringe tips are dispose into the disposal containers present in the lab or hospitals. Unused solid reagent is dispose in the manufacturer's container and then label the container with a hazardous waste tag so that people can't use it and stay away from it.
Broken flask is dispose in the cardboard box or a container. Titrant solution can also be dispose by placing in a container which is leak proof and closed the opening tightly so that it can't pollute and damaged the outside world.

Answer:
The final solution is 1.5 times more acidic than the initial solution
Explanation:
Ice floats because it is about 9% less dense than liquid water. ... The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over
Answer:
When the motion of the fluid results due to natural means like the buoyancy effect, that is, the elevation of the warmer fluid and the fall of the cooling fluid is termed as natural convection. Boiling water is the everyday illustration of the natural convection, in the process, the passing of the heat takes place from the burner into the pot, and heats the water present at the bottom.
On the other hand, when the fluid is forced to flow in a tube or over the surface by external means like with the help of a fan or a pump is termed as forced convection. The use of a fan on a hot summer day is an everyday illustration of forced convection. An example of effective heat transfer is the sweat produced by our body. Therefore, when one switches off the fan, the air present around the body captivates the water vapor until it gets saturated. It takes place for some time and stops eventually, which makes one feel hotter.
At that time, when the fan is switched back again, the air surrounding the body starts to move again, without completely getting saturated, and thus, evaporation of the sweat takes place that also contains the heat of the body and one feels cooler.
The basic law of mass conservation states that, the total mass of products of a chemical reaction should be equal to the total mass of reactants in the same reaction.
Applying this law to the above problem, we find that:
Total mass of reactants = 46 + 96 = 142 grams
This means that the total mass of products (water + carbon dioxide) should be also 142 grams
Since 52 grams of water is produced, therefore,
mass of carbon dioxide = 142 - 52 = 90 grams
