Which of the following choices contains the most thermal energy? a penny that is 20 degrees Celsius ( oC) an atom of aluminum th
jek_recluse [69]

Answer: a 900 milliliter (ml) pitcher of orange juice at 20 degrees Celsius ( oC)

Explanation:

Thermal energy is the energy possessed by an object by virtue of its temperature. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.

Thermal energy refers to the sum of kinetic, potential, vibrational ,electronic and rotational energies of the object.

For bodies at same temperature, the body with more molecules will have more thermal energy due to more collisions.

If i have 17 moles of gas at a temperature of 67c, and a volume of 88.89 liters what is the pressure of the gas
Shtirlitz [24]
Use the state equation for ideal gases: pV = nRT

Data:

V = 88.89 liter
n = 17 mol
T = 67 + 273.15 = 340.15 K

R = 0.0821 atm * liter / (K*mol)

=> p = nRT / V = 17 mol * 0.0821 (atm*liter / K*mol) * 340.15 K / 88.89 liter

p = 5.34 atm

Answer: p = 5.34 atm

1. A neutral atom of fluorine (F) has 9 electrons and an electron configuration of 1s2 2s2 2p5. How will it ionize to achieve an
Natasha2012 [34]
These answers dont make sense

1. the 2s2 orbital will give one of its electrons to the 2p5 orbital so the configuration would be 1s22s12p6 (2s1 is half filled and 2p6 is completely filled which is a much more stable configuration)

2. Neon does not need to ionize it is a noble gas

Which use of iron is due to its chemical properties?
Annette [7]

Answer:

changes from liquid to gas at 2,862°C

Explanation:

chemical changes are where you can't go back or change what's made. you can't change it after it's a gas.

Which of the following does not influence the effectiveness of a detergent? A-air temperature B-water temperature C-energy appli
Natasha2012 [34]

<em> A-air temperature does not influence the effectiveness of a detergent</em>

\boxed{\boxed{\bold{Further~explanation}}}

In chemical reactions several factors influence among others:

1. Temperature

The temperature of the reaction that is raised will cause the particles to move more actively so that collisions between particles will become more frequent so that the speed of chemical reactions will be greater

2. Pressure

Addition of pressure will increase the concentration because the volume is reduced, a greater concentration will accelerate the reaction

3. Concentration / substance level

The greater the level, the more substances dissolved and involved in the reaction, thereby increasing the speed of the reaction

4. Stirring

The mechanical force applied to the solution that reacts will cause more collisions to accelerate the reaction

5 Catalysts

Addition of a catalyst to accelerate the reaction without reaction with reactant substances

Detergents are used as cleaning removers of dirt on clothes or oily/fatty items

The main structure of detergent is surfactant which has hydrophobic (binding fat) and hydrophilic (which binds water) parts

Surfactants also function to reduce water surface tension so that it is easier to bind dirt

Surfactants can be anionic in which there are derivatives of Benzene, namely: Alkyl Benzene Sulfonate obtained from sulfonation reactions where hydrogen in benzene is substituted by sulfonate groups (HSO₃⁻) reaction with sulfuric acid (H₂SO₄)

If we see the answer choices:

A. Air temperature

Air does not play a role in the reaction or cleaning process of dirt by detergents, so it is not an effective or ineffective factor in detergent cleaning

B. Water temperature

The right water temperature by adjusting the conditions of clothing materials will increase the effectiveness of detergents, for example, hot temperatures suitable for lifting oil/oil stains, warm/cold temperatures for clothes that are not too dirty and made of silk/wool

C. Energy gave

The energy in the cleaning process can be done through mechanical energy so that the collision between the particles of detergent and dirt will occur more so that faster removal of dirt

D. the length and frequency of the treatment

Sufficient time and the frequency of contact between detergents and ingredients, especially for dirty and hard-to-lose materials, will make removal of dirt better
