Answer:

Conduction  

Conduction moves heat through direct sub-atomic crash. A region of more prominent dynamic energy will move nuclear power to a region with lower active energy. Higher-speed particles will crash into more slow speed particles. The more slow speed particles will increment in motor energy subsequently. Conduction is the most widely recognized type of warmth move and happens through actual contact. Models is place your hand against a window or spot metal into an open fire.  

The interaction of warmth conduction relies upon the accompanying components: temperature slope, cross-segment of the material, length of the movement was, and actual material properties. The temperature inclination is the actual amount that portrays the bearing and pace of warmth travel. Temperature stream will consistently happen from most sultry to coldest or, as expressed previously, higher to bring down active energy. Once there's warm harmony between the two temperature contrasts, the warm exchange stops.

Convection  

At the point when a liquid, like air or a fluid, is warmed and afterward ventures from the source, it conveys the nuclear power along. This sort of warmth move is called convection. The liquid over a hot surface grows, turns out to be less thick, and rises.

Radiation

Thermal radiation generates from the emission of electromagnetic waves. These waves carry the energy away from the emitting object. Radiation occurs through a vacuum or any transparent medium (either solid or fluid). Thermal radiation is the direct result of random movements of atoms and molecules in matter. Movement of the charged protons and electrons results in the emission of electromagnetic radiation.

Which of the following best describe the particles present in a 2.0 M aqueous solution of Al(NO3)3?2 M Al3+(aq) and 18 M NO3-(aq
zvonat [6]

Answer:

The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)

Explanation:

Step 1: Data given

2.0 M Al(NO3)3

Step 2:

Al(NO3)3 in water will dissociate as following:

Al(NO3)3 → Al^3+ + 3NO3^-

For 1 mol of Al(NO3)3 we will have 1 mol of Al^3+ and 3 moles of NO3^-

We know that the molarity of Al(NO3)3 = 2.0 M, this means 2.0 mol/ L

The mol ratio Al(NO3)3 and Al^3+ is 1:1 so the molarity of Al^3+ is<u> 2.0 M</u>

The mol ratio Al(NO3)3 and NO3^- is 1:3 so the molarity of NO3^- is<u> 6.0M</u>

The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)

During what part of the experiment is the hypothesis "judged" as being rejected or supported?
Blababa [14]

Answer:

null

Explanation:

the hypothesis is a typical statistical theory which suggest that no statistical relationship and significance exists in a set of a given single observed variable between two sets of the observed data and measured phenomena

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces
Brilliant_brown [7]

Answer:

0.364

Explanation:

Let's do an equilibrium chart for the reaction of combustion of ammonia:

2NH₃(g) + (3/2)O₂(g) ⇄ N₂(g) + 3H₂O(g)

4.8atm 1.9atm 0 0 Initial

-2x -(3/2)x +x +3x Reacts (stoichiometry is 2:3/2:1:3)

4.8-2x 1.9-(3/2)x x 3x Equilibrium

At equilibrium the velocity of formation of the products is equal to the velocity of the formation of the reactants, thus the partial pressures remain constant.

If pN₂ = 0.63 atm, x = 0.63 atm, thus, at equilibrium

pNH₃ = 4.8 - 2*0.63 = 3.54 atm

pO₂ = 1.9 -(3/2)*0.63 = 0.955 atm

pH₂O = 3*0.63 = 1.89 atm

The pressure equilibrium constant (Kp) is calculated with the partial pressure of the gases substances:

Kp = [(pN₂)*(pH₂O)³]/[(pNH₃)²*(pO_2)^{3/2}]

Kp = [0.63*(1.89)³]/[(3.54)²*(0.955)^{3/2}]

Kp = 4.2533/11.6953

Kp = 0.364
