Explanation:

If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.

Substance 1,

Mass, m = 450 g, Volume, V = 90 mL

Density = mass/volume

So,

[tex]d_1=\dfrac{450}{90}\\\\=5\ g/mL[/tex]

It will sink.

Substance 2,

Mass, m = 35 g, Volume, V = 70 mL

Density = mass/volume

So,

[tex]d_2=\dfrac{35}{70}\\\\=0.5\ g/mL[/tex]

It will float.

Substance 3,

Mass, m = 24 g, Volume, V = 12 mL

Density = mass/volume

So,

[tex]d_3=\dfrac{24}{12}\\\\=2\ g/mL[/tex]

It will sink.

Answer:

As nouns the difference between impression and imprint

is that impression is the indentation or depression made by the pressure of one object on or into another while imprint is an impression; the mark left behind by printing something.

The term imprint is defined as to mark by or as if by pressure and the term impression is defined as the effect produced by impressing.

The difference between an imprint and an impression is that the imprint is the mark left behind when anything is printed, whereas the impression is the indentation or depression caused by the pressure of one object against or into another.

While a shoe won't make an impression in loose sand, it will on a hard surface like concrete or linoleum. These imprints or impressions might be contrasted with the shoe of a suspect or the tire of a car to see if they belong to the same object.

Thus, The term imprint is defined as to mark by or as if by pressure and the term impression is defined as the effect produced by impressing.

Please find the explanation to this question below.

Explanation:

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

We have

[tex]P_2 = \frac{6.4 \times 0.87}{20.5} = \frac{5.568}{20.5} \\ = 0.2716.... \\ \\ = 0.27 \: \: \: atm[/tex]

But

1 atm = 14.7 psi

Then 0.27 atm =

The given diagram represents gaseous state of matter.  Both a volume and a definite form are absent from a gas. The separation of gas particles is great.

Solids, liquids, gases, plus plasma are the four states of matter that may be found in daily life. However, a number of additional states of matter have indeed been found.

Some of these additional states are created when a material transitions among two states of matter and doesn't actually exhibit the characteristics of either state. The most exotic are others. Both a volume and a definite form are absent from a gas. The separation of gas particles is great. The gas in a balloon and the air are two examples of gases. The given diagram represents gaseous state of matter.

3 moles of Calcium Oxide are formed

Explanation:

Based on the reaction of Calcium Ca, with oxygen, O₂, to produce calcium oxide, CaO is:

2Ca + O₂ → 2CaO

where 2 moles of calcium produce 2 moles of Calcium oxide.

That means, if 3 moles of Ca react in presence of oxygen:

3 moles of calcium oxide are formed

im guessing the Aurora Borealis

Answer:

5511.99 mL

Explanation:

Given data

Volume V1= 6052 mL

Temperature T1= 352K

Pressure P1= 892 mm Hg

At STP the parameters of  gas are

Temperature T2= 273.15 K

Pressure P2= 760 mmHg

Applying  the gas equation

P1V1/T1= P2V2/T2

Substitute to find V2 we have

892*6052/352= 760*V2/273.15

5398384/352= 760*V2/273.15

15336.31= 760*V2/273.15

Cross multiply

15336.31*273.15=  760*V2

4189113.0765=  760*V2

4189113.0765/760= V2

V2= 5511.99 mL

Hence the volume at STP is 5511.99 mL

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.
