Which solution would freeze at a lower temperature? Explain your reasoning.

Answers

Answer:

Explanation:

The solution which has the lowest freezing point temperature is one which has the highest depression in freezing point ( ΔT The depression in freezing point is a colligative property and depends on the number of solute particles. Greater is the number of solute particles, greater is the depression in the freezing point.

I would say the solution a because in the winter when it’s snowing they usually put salt which is NaCl on the road so it gets less slippery and i guess that’s why

The cheetah (Acinonyx jubatus) will be the subject of my discussion. Cheetahs are the world's fastest land mammals, and they have evolved in both physical and behavioural ways to improve their chances of having offspring.

What is the behavior of A Cheetah ?

First off, cheetahs have a highly effective circulatory system that includes bigger hearts and lungs, as well as a surplus of capillaries and red blood cells to carry oxygen to their muscles. This gives them the ability to pursue prey at speeds of up to 75 mph, increasing their likelihood of catching it and providing food for themselves and their young.

Second, cheetahs have a distinctive fur pattern that makes it simpler for them to blend into their surroundings and sneak up on their prey.and draw near enough for an effective assault. They can sprint rapidly and effectively because to their long legs and big feet.

Last but not least, cheetahs have a variety of behavioural modifications that improve their chances of having offspring. For instance, they create social groupings where the mothers look after the babies while the males go food hunting and guard the young from predators.

They also have a strong sense of smell that allows them to detect potential prey from far away. They get an edge in hunting and have a better probability of feeding their offspring as a result. In summary, cheetahs have a variety of morphological and behavioural adaptations that raise their likelihood of having offspring. Among these modifications is an extremely effective cardiovascular system.

Which option is an example of a chemical property?

melting point

density

ability to decompose

color

Answers

Answer:
The ability to decompose
Explanation:
A property is a chemical property when it changes the chemical structure of a substance after a reaction.
Density and color are both physical properties.
Even though melting point may seem like a chemical property, when something melts, only the physical state changes, and the chemical structure does not change, and therefore, is a physical property.
The ability to decompose is a chemical property. When something decomposes, the chemical structure of many molecules change, and therefore, is classified as a chemical property.

Ability to decompose

Which solute would be more effective at lowering the freezing point of water: MgCl2 and KNO3? Explain.

Answers

Answer:

AlCl₃.

Explanation:

Adding solute to water causes depression of the boiling point.

The depression in freezing point (ΔTf) can be calculated using the relation:

ΔTf = i.Kf.m,

where, ΔTf is the depression in freezing point.

i is the van 't Hoff factor.

van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.

Kf is the molal depression constant of water.

m is the molality of the solution (m = 1.0 m, for all solutions).

(1) NaCl:

i for NaCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

∴ ΔTb for (NaCl) = i.Kb.m = (2)(Kf)(1.0 m) = 2(Kf).

(2) MgCl₂:

i for MgCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.

∴ ΔTb for (MgCl₂) = i.Kb.m = (3)(Kf)(1.0 m) = 3(Kf).

(3) NaCl:

i for KBr = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

∴ ΔTb for (KBr) = i.Kb.m = (2)(Kf)(1.0 m) = 2(Kf).

(4) AlCl₃:

i for AlCl₃ = no. of particles produced when the substance is dissolved/no. of original particle = 4/1 = 4.

∴ ΔTb for (CoCl₃) = i.Kb.m = (4)(Kf)(1.0 m) = 4(Kf).

So, the ionic compound will lower the freezing point the most is: AlCl₃

MgC12 because it’s colder then anything else

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
