give an example of how an organism can use surface tension?

Answers

Answer 1

Answer:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Explanation:

Answer 2

Answer:

Examples of surface tension Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

As current flows through a system, what happens to the voltage available at each load?

Answers

Answer:

The relationship between Voltage, Current and Resistance forms the basis of Ohm's law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down.

If 2 moles of salt is dissolved to form 1 liter of solution, what is the molarity of the solution?

Answers

Answer:

2M

Explanation:

Molarity refers to the molar concentration of a solution. It can be calculated by using the formula as follows:

Molarity (M) = number of moles (n) ÷ volume (V)

Based on the information provided in this question, 2 moles of salt is dissolved to form 1 liter of solution. This means that n = 2mol, V = 1L

Molarity = n/V

Molarity = 2/1

Molarity = 2M

Ammonia (NH3) dissolved in water is heated in a beaker. If initially there had been 60 grams dissolved in 100 grams of water, what would happen if the temperature reached 90℃ and why? A. The solution would become supersaturated and the ammonia would all remain dissolved . B. The solution would become saturated but the amount of ammonia dissolved would remain the same . C. about 50 more grams of ammonia would be able to dissolve as the solution has become unsaturated . D. about 50 grams of ammonia would come out of solution as the temperature caused the solubility to decrease .

Answers

Answer:

C. About 50 more grams ammonia would be able to dissolve as the solution has become unsaturated

Explanation:

From the question, we have;

The mass of ammonia dissolved in water = 60 grams

The mass of the water solvent which dissolves the ammonia = 100 g

The temperature to which the ammonia water solution is raised = 90°C

Therefore, given that the solubility of a solute in a solvent increases with temperature, when the temperature is raised, we have, that the solution will more unsaturated and will be able to dissolve more ammonia, therefore, option 'C' is the most correct option that corresponds with the relationship of temperature and solubility

The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be ____ and are delocalized around the ring.

Answers

Answer: The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.

Explanation:

Chemical compounds that have conjugated planar ring systems where there are delocalized pi-electron clouds are present in place of individual alternate and single bonds.

This means that electrons present in a double bond of alkene are in conjugation.

Therefore, we can conclude that the double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.

If 95 grams of Iron are needed to react with sulfur, how many grams of sulfur are involved in this reaction?
2 Fe + 3 S=Fe2S3

Answers

Answer:

82 g S

Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 81.6 grams of sulfur are involved in this reaction.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

2 Fe + 3 S[tex]\rightarrow[/tex]Fe[tex]_2[/tex]S[tex]_3[/tex]

mass of iron = 95 grams

Molar mass of iron=55.8450 g/mol

number of moles of iron =Given mass÷ Molar mass of iron

number of moles of iron=95÷ 55.8

number of moles of iron=1.70 moles

The mole ratio between iron and sulfur is 2:3

moles of sulfur = (3/2) moles of iron

moles of sulfur = (3/2)×1.70

moles of sulfur=2.55 moles

Mass of sulfur= number of moles of sulfur× Molar mass of sulfur

                       =2.55× 32

                       =81.6g

Therefore, 81.6 grams of sulfur are involved in this reaction.
