8. Converting Units The volumes in your data are in millimeters, which are equivalent to cubic centimeters, cm3. But your areas

are in units of square meters (m2). To combine these, you will have to convert to similar units. Convert one of your volume measurements from units of cm3 to units of m2, showing your work. (Remember that 1 ×106 cm3 = 1 m2.)

Answer:

This question is a practical question and hence incomplete

Explanation:

However, there are some steps that can be followed to achieve the aim of this question.

To convert millimeters (mm) to cubic centimeters (cm³), the value in millimeter will have to be divided by 1000. This is because 1 mm equals 0.001 cm³. Hence, if the volume in the data is 30 mm, the equivalent in cm³ will be

30/1000 = <u>0.03 cm³</u>

OR

1 mm ⇒ 0.001 cm³

30 mm ⇒ ?

Let's assume the unknown (?) is X

1 × X = 30 × 0.001

X = <u>0.03 cm³</u>

Hence, 30 mm equals 0.03 cm³

Also, to convert any volume from cubic centimeter (cm³) to square meter (m²), you will divide the unit in cm³ by 1 × 10⁶ (1,000,000). To convert the value obtained earlier (0.03 cm³ or 3 × 10⁻² cm³) to m², you will

1,000,000 cm³ ⇒ 1 m²

0.03 cm³ ⇒ ?

Let's assume the unknown (?) is Y

1000000 × Y = 0.03 × 1

Y = 0.03/1000000 OR you can write it as 3 × 10⁻² × 10⁻⁶

Y =  <u>3 × 10⁻⁸m²</u>

Hence, 0.03 mm equals <u>3 × 10⁻⁸ m²</u>

A buffer is prepared by adding 12.0g of ammonium chloride (NH4Cl) to 250mL of 1.00 M NH3 solution?The pH is 9.3 Write the net io
solniwko [45]

Answer:- NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)

Explanations:- The solution we have is a buffer solution and we know that a buffer solution resists a change in its pH if a strong acid or base is added to it.

Here, the buffer solution we have is of a weak base and it's conjugate acid. So, a strong acid(nitric acid) is added to this buffer then it reacts with the base present in the buffer so that the acid could be neutralized. This is called buffer action.

The net ionic equation is written as:

NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)

Note that HNO_3 is a strong acid and nitrate ion is the spectator ion so it is not included in the net ionic equation.

Why does buck ministerfullerene act as a good lubricant
MakcuM [25]

Answer:

Its molecules are made up of 60 carbon atoms joined together by strong covalent bonds. Molecules of C 60 are spherical. There are weak intermolecular forces between molecules of buckminsterfullerene. These need little energy to overcome, so buckminsterfullerene is slippery and has a low melting point.

A 2.2 M solution is made by with 0.45 moles of a solute. What is the final volume of this solution?
Savatey [412]

Answer: The final volume of this solution is 0.204 L.

Explanation:

Given: Molarity of solution = 2.2 M

Moles of solute = 0.45 mol

Molarity is the number of moles of solute present divided by volume in liters.

Molarity = \frac{no. of moles}{Volume (in L)}

Substitute the values into above formula as follows.

Molarity = \frac{no. of moles}{Volume (in L)}\\2.2 M = \frac{0.45}{Volume}\\Volume = 0.204 L

Thus, we can conclude that the final volume of this solution is 0.204 L.

How many moles are found in 10.5 g of Pb?
deff fn [24]

Answer:

Number of moles = 0.05 mol

Explanation:

Given data:

Mass of Pb = 10.5 g

Number of moles of Pb = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of Pb is 207.2 g/mol.

Now we will put the values in formula.

Number of moles = 10.5 g/207.2 g/mol

Number of moles = 0.05 mol
