A disadvantage of disposing of waste polymers through _____ is that they must first be separated, which can be expensive. What is the missing word in this sentence?

Answers

A disadvantage of disposing of waste polymers through recycling is that

they must first be separated.

Recycling is the process of forming new polymers and compounds as against their disposal .

Recycling involves separating the items into various sections such as paper,

plastic , metal etc. This is because they both undergo different recycling

processes.

The disadvantage of this process is that it's time consuming and also

expensive as a great amount of time and man power is needed to

separate the waste items.

put these atoms in order of increasing radius: Na, Mg,Cl, P

Answers

Answer:

Cl < P < Mg < Na

Explanation:

Cl must have the smallest radius because it is located to the right of the remaining elements on the same row. P  must have the second smallest radius because it is located to the right of the remaining elements on the same  row. Mg must have the Third smallest radius because it is located to the right of Na on the same row.  Therefore, Na has the Largest radius.

When a gas is collected over water, the partial pressure of water must be subtracted from the total pressure. If the total pressure was 761 mmHg and the pressure for water is 17.2 torr, what is the pressure due to the gas collected

Answers

Answer is: the partial pressure of the hydrogen 500 mmHg.

p(total) = 523.8 mmHg.

p(water) = 23.8 mmHg.

p(total) = m(water) + p(hydrogen).

p(hydrogen) = p(total) - p(water)..

p(hydrogen) = 523.8 mmHg - 23.8 mmHg.

p(hydrogen) = 500 mmHg.

mmHg or millimeter of mercury is a manometric unit of pressure.

what is the total number of valence electrons in ethyl acetate?

Answers

Answer: There are 36 valence electrons.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.

Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}

Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}

Valence electrons of C₄H₈O₂=32

Therefore, the valence electrons of C₄H₈O₂ is 32.

The energy released by a nuclear fusion reaction is produced when
1. energy is converted to mass
2. mass is converted to energy
3. heat is converted to temperature
4. temperature is converted to heat

Answers

Answer:

2

Explanation:

energy produced in nuclear fusion or even fission is due to mass defect and it can be calculated by Einstein equation e=mc2

The statement, that describes energy released by a nuclear fusion reaction is produced is "mass is converted to energy."

What is nuclear fusion?

Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process.

A fusion reaction occurs when two light nuclei combine to form a single heavy nucleus. Because the overall mass of the resulting single nucleus is smaller than the mass of the two initial nuclei, the process releases energy.

That is, nuclear energy refers to the energy released as a result of mass loss during the nuclear fusion processes. Both of these processes transform mass loss into energy in accordance with Einstein's mass-energy ratio, E = [tex]mc^{2}[/tex]. As a result of the fusion reaction, mass is destroyed and energy is released.

Hence, the correct answer is 2.

How many atoms are there in 7.02 g Si ?

Answers

Answer:

1.51e23 atoms

Explanation:

First, using the molar mass of Si (28.1 g/mol), determine the # of moles of Si we have. Then use Avogadro's number (6.022e23 atoms = 1 mol) to convert the # of moles to the # of Si atoms.

(7.02 g Si)([tex]\frac{1 mol}{28.1 g}[/tex]) = 0.250 mol Si              

(0.250 mol Si)([tex]\frac{6.022*10^{23} atoms }{1 mol}[/tex]) = 1.51e23 atoms    

The atomic mass of Silicon (Si) is 28.09 g/mol. The no. of atoms present in 7.02 g of Si is 1.46 × 10²³.

What is a mole?

Any substance containing  6.022 × 10²³ atoms is called one mole of that substance.  The no.of moles can be calculated by dividing the given weight by the atomic mass of the substance.

Atomic mass of Si = 28.09 g/mol

      Given mass    = 7.02 g.

       No.of moles  = 7.02 g/ 28.09 g/mol

                             = 0.24 moles

One mole contains  6.02 × 10²³ atoms. Thus 0.24 mole of Si contains  6.02 × 10²³ × 0.24  = 1.46 × 10²³ atoms.

Hence, no.of atoms present in 7.02 g of Si is 1.46 × 10²³ .
