You wish to prepare a tape-casting slip containing 50 vol% Al2O3 and 50 vol% polyvinyl butyral (PVB) binder. If the density of A

l2O3 is 3.98 g/cm and that of PVB is 1.08 g/cm?, how many of grams of PVB are required to produce 1000 g of tape?

<u>Answer:</u> The mass of PVB required to produce 1000 grams of tape is 213.4 grams

<u>Explanation:</u>

To calculate the mass of aluminium oxide, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}       .......(1)

  • <u>For Al_2O_3</u>

We are given:

50% (v/v) of Al_2O_3

This means that 50 mL of aluminium oxide is present in 100 mL of tape

Calculating the mass of aluminium oxide by using equation 1:

Density of aluminium oxide = 3.98 g/cm^3

Volume of aluminium oxide = 50mL=50cm^3     (Conversion factor:  1mL=1cm^3 )

Putting values in equation 1, we get:

3.98g/cm^3=\frac{\text{Mass of aluminium oxide}}{50cm^3}\\\\\text{Mass of aluminium oxide}=(3.98g/cm^3\times 50cm^3)=199g

Mass of aluminium oxide = 199 g

  • <u>For PVB:</u>

We are given:

50% (v/v) of PVB

This means that 50 mL of PVB is present in 100 mL of tape

Calculating the mass of PVB by using equation 1:

Density of PVB = 1.08 g/cm^3

Volume of PVB = 50mL=50cm^3

Putting values in equation 1, we get:

1.08g/cm^3=\frac{\text{Mass of PVB}}{50cm^3}\\\\\text{Mass of PVB}=(1.08g/cm^3\times 50cm^3)=54g

Mass of PVB = 54 g

Mass of tape = Mass of aluminium oxide + mass of PVB

Mass of tape = [199 + 54] g = 253 g

To calculate the mass of PVB required to produce 1000 g of tape, we use unitary method:

When 253 grams of tape is made, the mass of PVB required is 54 g

So, when 1000 grams of tape is made, the mass of PVB required will be = \frac{54}{253}\times 1000=213.4g

Hence, the mass of PVB required to produce 1000 grams of tape is 213.4 grams

Which of the following can be measured in amps with an ammeter
alexdok [17]
I believe it is current. An ammeter is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, milliampere or microampere range, are designated as milliammeters or microammeters.

What type of covalent bond is formed between amino acid molecules during protein synthesis? peptide bond electrovalent bond hydr
Brums [2.3K]

The type of covalent bond is formed between amino acid molecules during protein synthesis will be  <u>"peptide bond".</u>

<u />

A peptide bond would be a sort of covalent link that connects an amino acid's carboxyl group to its amino group. Amino acids itself were comprised of atoms bonded together through covalent bonds.

Two atoms share an electron pair equally in a covalent link. Peptide (amide) but also disulfide links between amino acids, as well as C-C, C-O, and C-N bonds within amino acids, represent examples of significant covalent bonds.

Therefore, the type of covalent bond is formed between amino acid molecules during protein synthesis will be  <u>"</u><u>peptide bond"</u><u>.</u>

Match each element to the number of electrons in its valence shell.
irinina [24]

Answer:

C: 4

H: 1

Mg: 2

O : 6

Explanation:

You can quickly find out the number of valence electrons by looking at where the element is on the periodic table and referring to the table that is attached.
