The cart starts out in position A with high potential energy, low kinetic energy, and some thermal energy. As the cart progresses into position B, the kinetic energy begins to increase and the potential energy begins to decrease; as the thermal energy increases as thermal energy from the track is transferred to the cart through friction. Once the cart reaches position C, it has high kinetic energy, low potential energy, and some thermal energy. At position D, the cart has high potential energy, low kinetic energy, and some thermal energy. The potential energy throughout is correlated to gravity, the kinetic energy is correlated to momentum, and the thermal energy is correlated to friction. The potential energy is at its maximum during position A, and its minimum at position C; the kinetic energy is at its maximum during position C, and its minimum at position A; the thermal energy is at its maximum during position B, and its minimum at position A

Explanation:

Why do atoms exchange or share electrons during bonding?

to obtain a full outer electron shell


to attract an ion with the opposite charge


to become neutral


to have eight inner level electrons

Answers

Answer:

to obtain a full outer shell

Explanation:

The atoms of some elements share electrons because this gives them a full valence shell. ... If atoms can't achieve a full outer shell by transferring electrons, they resort to sharing. In this way, each atom can count the shared electrons as part of its own valence shell. This sharing of electrons is covalent bonding.

Atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

What is Chemical bonding?

Chemical bonding may be defined as a type of interaction that is significantly accomplished through the association of atoms into molecules, ions, crystals, and other stable species that make up familiar substances.

According to the context of this question, the atoms of some elements typically transfer their electrons to the other elements in order to achieve a fully filled outermost shell.

If they do not have a tendency of transferring, they follow a different mechanism of sharing their electrons. The sharing of electrons gives rise to the formation of covalent bonding.

Therefore, atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

molecular formula of sulphur trioxide by criss cross method ​

Answers

Answer:

Sulfur trioxide: SO3.

Explanation:

How I came to this conclusion:

I noticed that the compound consists of non-metals, therefore it must be a covalent compound -

meaning I use prefixes for compounds.

Sulfur is S. Simple enough. Trioxide has the prefix of tri, meaning "3". Therefore there is 3 atoms of oxygen. Combine them and I get SO3.

Don't be confused with sulfite: (SO3)2− and sulfate: (SO4)2−

What amount of heat (in kJ) is required to convert 19.8 g of an unknown liquid (MM = 83.21 g/mol) at 19.2 °C to a gas at 93.5 °C? (specific heat capacity of liquid = 1.58 J/g・°C; specific heat capacity of gas = 0.932 J/g・°C; ∆Hvap = 22.5 kJ/mol; normal boiling point, Tb = 57.3°C)

Answers

The total energy required to convert the unknown liquid to gas at the given temperature is 7.215 kJ.

The given parameters;

mass of the unknown liquid, m = 19.8 gmolar mass of liquid = 83.21 g/molinitial temperature of the liquid, = 19.2 °Cboiling point temperature of the liquid, = 57.3°Cfinal temperature of the liquid = 93.5 °C

The total heat required to convert the liquid to gas is calculated as follows;

H = Heat to raise to boiling temp. + Heat to vaporize the liquid + Heat of gas vapor

The heat required to raise the temperature of the liquid to boiling point;

[tex]H_1 = mc\Delta t\\\\H_1 = 19.8 \times 1.58 \times (57.3 - 19.2)\\\\H_1 = 1,191.92 \ J\\\\H_1 = 1.1919 \ kJ[/tex]

The number of moles of the liquid is calculated as;

[tex]moles= \frac{19.8 \ g}{83.21 \ g/mol} = 0.238 \ mol[/tex]

The heat required to vaporize the liquid;

[tex]H_2 = n H_{vap}\\\\H _2 = 0.238 \times 22.5\\\\H_2 = 5.355\ kJ[/tex]

The heat of the gas vapor is calculated as;

[tex]H_3 = mc_g \Delta t\\\\H_3 = 19.8 \times 0.932 \times (93.5- 57.3)\\\\H_3 = 668.02 \ J\\\\H_3 = 0.668 \ kJ[/tex]

The total energy required to convert the unknown liquid to gas at the given temperature is calculated as;

[tex]H_{total} = 1.1919 \ kJ \ + \ 5.355 \ kJ \ + \ 0.668 \ kJ\\\\H_{total} = 7.215 \ kJ[/tex]

Thus, the total energy required to convert the unknown liquid to gas at the given temperature is 7.215 kJ.

1.5 of potassium ioxcide in 150cm^3 of solution

Answers

Answer:

Explanation:

I'm not sure what is being asked, not the units of "1.5."  I don't know of potassium "ioxicide."  Was "dioxide" intended?

I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).

The molar mass of K2O, potassium dioxide, is 94.2 g/mole.  1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O.  The definition of Molar is moles/liter.  So take the moles of K2O and divide by the liters, which is 0.150L in this case.

(0.0159 moles K2)/0.150 L  = 0.106 M K2O

El agua se purifica a partir de un proceso de filtrado. Las características que evidencian el filtrado incluyen pH normal, color cristalino, ausencia de metales pesados y/o microorganismos, etc.

Los filtros para purificar agua son dispositivos que permiten el limpiado del agua con el objetivo de convertirla apta para consumo humano.

En general, los filtros para lograr la purificación del agua consisten de carbón activado, el cual se prensa con alta presión.

Este dispositivo de carbón activado permite secuestrar las partículas sólidas que pasan a través del filtro, con lo cual el agua sale a través del filtro completamente purificada.

Las características que permiten determinar si el agua ha sido correctamente filtrada incluyen:

El agua sale cristalina, es decir, sin ningún tipo de color que evidencie la presencia de contaminación.El pH del agua potable debe oscilar entre valores normales (6,5 a 8,5)No debe contener metales tales como plomo, arsénico o cadmio (altamente tóxicos)No debe contener microorganismos

Environmental factors can affect an organism's appearance, behavior, and health. For example, in certain reptiles, the temperature of the environment may determine the sex of the offspring. Both genetics and environmental factors determine the observable, physical characteristics of organisms, also called their _______________ in genetics.

a. phenotypes

b. organelle

c. morphology

d. genotype

Answers

Answer:

Phenotype

Explanation:

The observable physical characteristics of an organism, as determined by both genetic makeup and environmental influences.

The question is asking about the observable physical characteristics of organisms.

We can eliminate options B and C because they don't make much sense. An organelle is a structure in a cell which conducts cellular functions, and the morphology of an organism is basically the anatomy and physiology of the organism, which isn't quite what we're looking for.

Keeping this in mind, here is some information on prefixes:

geno - relating to genes

pheno - relating to what's observable

The second one sounds a lot like what we're looking for, and just in case, the definition of phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Therefore your answer is: A. phenotypes

Explanation:

ácido clorhídrico = HCl

M = m/Mr × 1000/mL

0.2 M = m/36.5 gr/mol × 1000/500 mL

0.2 M = m/36.5 gr/mol × 2

m/36.5 gr/mol = 0.2 M/2/L

m/36.5 gr/mol = 0.1 mol

m = 36.5 gr/mol × 0.1 mol

m = 3.65 gram
