The physical properties of each material can be used to tell each apart. One example of these properties is their respective densities and polarities, among others.

In the case of Cork and Lead, we can name differences such as:

  1. Densities, since lead has a very high density when compared to the low density of cork
  2. Colors, given that lead is a blueish silver color and cork is not.
  3. Melting points are another way to tell them apart since lead melts at 330 degrees while cork begins to melt at 200.

As for copper and silver, though not identical in numbers, both elements share a wide range of properties. One physical property to be used when telling them apart is color, as silver has its own aptly named color whilst copper shines in a bright brown-red coloration.

As opposed to the previous group, benzene and water can often be physically identical. However, this does not mean that they share all physical properties. One example of this and a property that can tell them apart is their polarity, given that water is highly polar and benzene is not polar at all.

Of the groups listed, the grouping of sulfur and iron is the easiest to differentiate given that they possess distinct:

  • Color
  • Melting points
  • Boiling points
  • Odors
  • Conductivities

and so on.

These are some properties that are different between each grouped elements and can be used by scientists or students to differentiate the substances from one another.

The oxidizing agent our bodies use to obtain energy from food is oxygen (from the air). If you breathe 15 times a minute (at res
Misha Larkins [42]

Answer:

Explanation:

Given parameters:

Number of breathe per minute = 15times

Volume of air per breath = 0.5L

Percentage of oxygen in air = 21%

Solution

There are 24 hours in a day.

 60minutes makes a hour in a day,

I will breathe:

           15 times x 60 x 24  = 21600 times in a day

The volume of air I will take in per day:

       A breathe = 0.5L of air

    21600breathe = 0.5 x 21600 = 10800L of air

Volume of oxygen I will breathe per day:

    \frac{21}{100} x 10800 = 2268L of oxygen

How many molecules are there in 45.0 grams of CH ?
Sonbull [250]

Answer:

There are 1.8021 ⋅ 1024 molecules of CH4 in 48 grams of CH4. To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass. A mole is just a unit of measurement. Avogadro's number is equal to 6.022 ⋅1023 molecules/mole. i think please dont complain to me if its wrong im sorry

In an extraction experiment similar to your expt. 4, you attempt to separate 2-naphthol from cyclohexane, both of which are diss
Viktor [21]

Answer:

[a]. 108 mL.

[b].

1. use HCL in washing for the neutralization of NaOH.

2. Wash with water.

3. make use of MgSO4 to remove water traces.

4. Evaporate to get the pure cyclohexane

Explanation:

The chemical equation for the reaction between 2-naphthol and Sodium hydroxide is given below as:

C₁₀H₈O + NaOH --------------------------------------------------> C10H7O⁻ Na⁺ + H₂O.

The C10H7O⁻ Na⁺ is  the aqueous phase.

The molarity of Sodium Hydroxide is = [ (mass of sodium hydroxide ) ÷ molar mass sodium  hydroxide × volume] × 1000.

The molarity of sodium hydroxide = [ (5/40) × 100] × 1000 =  1.25 M.

The number of moles of 2-naphthol = mass / molar mass =  20 / 144.17 = 0.138 moles.

Recall that, the formula for the number of moles = concentration × volume. Therefore, the volume of sodium hydroxide is given below as:

Volume of sodium hydroxide = the number of moles of sodium hydroxide ÷  concentration of sodium hydroxide = 0.138 ÷  1.25 = 0.108L = 108 mL.

In order to efficiently isolate relatively pure cyclohexane from the ether layer, the following process must be followed:

1. use HCL in washing for the neutralization of NaOH.

2. Wash with water.

3. make use of MgSO4 to remove water traces.

4. Evaporate to get the pure cyclohexane

On a molecular level, explain how pure water can act as both an acid and a base.
Mila [183]
On a molecular level, water which was H2O can be divided into H+ and OH- ion. Therefore, water has an acid component which was H+ and a base component which was OH-. The water is at neutral pH of 7 not because there are no acid and base, but because the amount of acid and base is equal.
