The answer is benedict’s reagent.  Benedict’s test is used to detect reducing sugars in solution when heated. The color change occurs from clear blue to a brick-red precipitate in the presence of the reducing sugars. The cupric compounds in the benedicts reagent react with the reducing sugars (enediols) produced from heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and copper(II) sulfate pentahydrate.

The-attraction of the positive side of one water
Anna71 [15]

Answer:

B = hydrogen bonding

Explanation:

The water molecule consist of two hydrogen atom one oxygen atom. There is large electronegativity difference between oxygen and hydrogen. Both atoms are bonded through covalent bonds.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial negative.  The partial positive end of one water molecule attracted towards the partial negative end of other moleucle. The attraction between them is called hydrogen bonding. In this way large mole are connected with each other. Hydrogen bonding is actually a weak bonding.

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
Katyanochek1 [597]

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

Length = 10cm

Robert:

1 glass marble

Diameter = 10cm

Susan:

1000 glass marble

Diameter = 1cm

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

Volume = Length^3

Substitute 10cm for Length

Volume = 10^3

Volume = 1000cm^3

Next, calculate the volume of Robert's glass

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 10cm --- Given

Substitute 10 for diameter

r = \frac{1}{2} * 10cm

r = 5cm

So:

Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 5^3

Volume = \frac{4}{3} * \frac{22}{7} * 125

Volume = 523.8cm^3

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 1cm --- Given

Substitute 1cm for diameter

r = \frac{1}{2} * 1cm

r = 0.5cm

Substitute 0.5cm for radius in Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.125

Volume = 0.5238

But there are 1000 glasses.

So, the volume of 1000 glasses is:

Volume = 0.5238 * 1000

Volume = 523.8cm^3

--------------------------------------------------------------------------------------------------------------

For Robert:

Volume = 523.8cm^3

For Susan:

Volume = 523.8cm^3

Since, they have the same volume.

Both boxes have the same amount of empty space
