A small sample of an organic compound (a nonelectrolyte) was added to benzene (Freezing point = 5.5°C)

Chemistry
1 answer:
Alja [10]3 years ago
3 0

The new lowered freezing point of the benzene mixture is determined as 2.4°C.

<h3>Effect of impurities in freezing point</h3>

The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.

Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C

New freezing point = 5.5°C - 3.1°C = 2.4°C

Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

What should we do to reduce the risk when working with concentrated acids and bases
Solnce55 [7]

What should be done to reduce the risk when working with concentrated acids and bases are;

<em><u>1) Ensure that the concentrated acids and bases are stored separately in safety cabinets. </u></em>

<em><u>2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments. </u></em>

<em><u>3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.</u></em>

          When working with strong acids and bases during neutralization reactions, usually the production of gases can make the solution which is corrosive to splash and get to people around there.

         Due to how strong the acids and base are, these splashes from the neutralized solution could have potentially damaging effects on humans when it contacts them by either casing skin burns or even blindness.  

Now, to reduce the risk of the adverse effects stated above, what could be done is;

1) Ensure that the concentrated acids and bases are stored separately in safety cabinets.

2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments.

3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.

State 2 ways in which adaptation help animals?
QveST [7]
Camouflage, mimicry, and animals' body parts and coverings are physical adaptations. The way in which an animal behaves is an adaptation, too—a behavioral adaptation . Behaviors that animals are born knowing how to do are instincts . A lion preying upon a zebra and a bird building a nest are examples of instincts.

Which of the following statements is true about hydropower?
san4es73 [151]

Answer:

Answer C: It can affect fish and other marine life.

Explanation:

Hydropower plants can harm ecosystems, especially killing fish with their turbines.

Note: Hydropower generators do not directly emit air pollutants. However, dams, reservoirs, and the operation of hydroelectric generators can affect the environment. And greenhouse gases (GHG) such as Carbon Dioxide (MENTIONED IN ANSWER A) and methane form in natural aquatic systems and in human-made water storage reservoirs as a result of the aerobic and anaerobic decomposition of biomass in the water.

However, if we can choose just the only one answer, then the answer is C.
