What of these should Hailey include in her list?

Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.

Answers

Answer 1

Answer:

Hailey should add, they are inexpensive to produce.

Explanation:

Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.

Reason being why the others are wrong, synthetic polymers are not biodegradable as they are made in a factory with oils. Synthetic polymers are not flexible due to them being used for harder products. Synthetic polymers are not recycled cheaply as they are made with chemicals which makes it very hard to recycle.

When calculating the amount of product formed during alcohol fermentation, one mole of ethanol is chemically equivalent to what volume of CO2 (g) measured at 1 atm and 273 K

Answers

Answer:

44.8 dm^3

Explanation:

The equation for the fermentation of glucose is;

C6H12O6 -----> 2C2H5OH + 2CO2

This means that two moles of ethanol carbon dioxide are produced.

If 1 mole of gas at STP occupies 22.4 dm^3, then two moles occupies; 22.4 dm^3 × 3 = 44.8 dm^3

Answers

Isotopes are atoms of the same element that have different numbers of neutrons. Protons are positively-charged particles found in the nucleus of an atom.

Electrons are negatively-charged particles found in the outer shell of an atom. The charge on an element is determined by the number of protons and electrons present in the atom.

a.) Li+:  number of protons = 3

Number of electrons = 2

charge of Li+ = +1

b.) Be2+: number of protons = 4

Number of electrons = 2

charge of Be2+ = 2+

c.) C4+: number of protons = 8

Number of electrons = 4

charge of C4+ = 4+

d.) O2-: number of protons = 8

Number of electrons = 10

charge of O2- = -2

e.) N3-: number of protons = 7

Number of electrons = 10

charge of N3- = -3

f.) C4- : number of protons = 4

Number of electrons = 4

charge of C4- = -4

g.) 14C6: The mass number = 14

Atomic number = 6

Number of neutrons = 8

h.) 18O8:  The mass number = 18

Atomic number = 8

Number of neutrons = 10

i.) 19F9:  The mass number = 19

Atomic number = 9

Number of neutrons = 10

j.) 40Ca20:  The mass number =40

Atomic number = 20

Number of neutrons = 20

k.) 37Cl17:  The mass number = 37

Atomic number = 17

Number of neutrons = 20

l.) 238U92:  The mass number = 238

Atomic number = 92

Number of neutrons = 146

Indirect causes of disease are always passed down from parents.

Indirect causes of disease can trigger genes, leading to types of cancer.

Indirect causes of disease include infections and pathogens

Answers

Answer:indirect causes of disease include genetics, lifestyle, and environmental factors

Explanation:

The indirect disease -causing factors include some genetic factors, infections from other persons etc. Thus options A ,C and D are correct.

What are indirect disease -causing factors?

There are some factors such as infection from other people make us infected also not by directly originating in ourselves. For example, passive smokers may have respiratory disorders.

Some disease can be generated indirectly from the gene types inherited from parents. These may cause imperfect gene coding and some times trigger cancer.

Infections such as flu, cold, different types of fevers, viral and bacterial infection are able to spread and might affect other two-three people.

Therefore, indirect disease -causing factors includes genetic disorders inherited from parents and infections from environment and hence options A, C and D are correct options.

1. Se preparan 750 ml de una disolución en agua, que contiene 0,00071 moles de Nitrato de potasio para adobar una carne de res. Calcular la ppm de la disolución. 2. Una muestra de 600 ml de disolución tiene 4 mg de ión fluoruro (F-). Cuántas ppm de F hay en la muestra?. Ayudaaaaaa plis

Answers

Answer:

1. 95.7 ppm

2. 6.67 ppm

Explanation:

Podemos pensar la denominación ppm como partes por millón, es un tipo de unidad que define concentración de solutos en una solución.

ppm = μg/g  o si lo queremos ver en volumen, μg/mL

Quiere decir microgramos de soluto en 1 g de solución o mL de solución.

Ej 1.  En primer lugar convertimos los moles de KNO₃ a gramos

0.00071 mol . 101.1 g/mol = 0.071781 g

Si pasamos los gramos a μg → 0.071781 g . 1000000 μg/ 1g = 71781 μg

Dividimos 71781 μg /750 ml = 95.7 ppm

Ej 2. Convertimos los mg a μg → 4 mg . 1000 μg/ 1 mg = 4000 μg

Ahora dividimos: 4000 μg /600 ml = 6.67 ppm

A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol

Answers

Answer:

ΔG =   18KJ/mol

Explanation:

Given data:

ΔS = 0.09 Kj/mol.K

ΔH = 27 KJ/mol

Temperature  = 100 K

ΔG = ?

Solution:

Formula:

ΔG = ΔH - TΔS

ΔS = entropy

ΔH = enthalpy

by putting values,

ΔG =  27 KJ/mol - 100K(0.09 Kj/mol.K)

ΔG =  27 KJ/mol - 9 KJ/mol

ΔG =   18KJ/mol

Answer:

ΔG = 18kJ/mol

If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?

Answers

Answer:

160N

Explanation:

F = m × a

Where;

F = force (Newton)

m = mass (kg)

a = acceleration (m/s²)

According to this question, a 50kg car is pulling a 30kg car. This means that the total mass of the cars is 50kg + 30kg = 80kg

Hence, the force required to accelerate the cars at 2m/s² can be calculated this:

F = 80 × 2

F = 160kgm/s²

F = 160N
