Air temperature and air pressure both decrease

The air pressure is low at higher altitudes. The pressure decreases up the higher altitudes. Same with temperature, as we go up the higher altitudes the temperature decreases as molecules becomes more far apart.

altitude ↑ || pressure ↓

altitude ↑ || temperature ↓

If the ligand has a negative charge at a particular location, what would happen if you tried to put electrons from the metal nea

slega [8]

Answer:

The two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place

Explanation:

A complex is made up a central metal atom or ion and ligands. Ligands are lewis bases and they possess lone pairs of electrons. A complex is formed when electrons are donated from ligand species to metals.

However, if the ligand has a negative charge at a particular location and we try to put electrons from the metal near the electrons from the ligand, the two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place.

Write the chemical formula for a molecule of non cyclic amp.

RSB [31]

The structural formula shown in the picture is the cyclic AMP or cyclic adenosine monophosphate. It is an essential component in RNA synthesis and metabolic processes. When it becomes non-cyclic after enzymatic reaction, you would have to disconnect the cyclic rings. When you do, you add 2 H atoms, one for each terminal end. The formula for cyclic AMP is C₁₀H₁₄N₅O₇P. Since there are three cyclic rings, you would have to add 6 hydrogen atoms. Thus, the formula for noncylic AMP is C₁₀H₂₀N₅O₇P.

The graphs above show Maxwell-Boltzmann distributions for one-mole samples of Ar(g). Graph 1 shows the distribution of particle

Aleks [24]

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature.

<h3>What is Maxwell-Boltzmann distributions?</h3>

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature. Recall that at the same temperature, the relative speed of gas molecules is described by the Maxwell-Boltzmann distributions.

The question is incomplete hence we can not be able to show the exact relationship between the two graphs in order to arrive at a justification for the student's claim.

A 45g Aluminum spoon (specific heat 0.88J/g degree Celcius) at 24 degrees Celcius placed in 180ml(180g) of coffee at 85 degrees

yarga [219]

Answer:

82 °C

Explanation:

Let the specific heat capacity of the coffee be that of water which is 4.2 J/g °C.

Now, at the final temperature, heat gained by Aluminum spoon ,Q equals heat lost by coffee, Q'.

Q = -Q'

Q = m₁c₁(T₂ - T₁) where m₁ = mass of aluminum spoon = 45 g, c₁ = specific heat of aluminum = 0.88 J/g °C, T₁ = initial temperature of aluminum spoon = 24 °C and T₂ = final temperature of aluminum spoon.

Q' = m₂c₂(T₂ - T₃) where m₂ = mass of coffee = 180 g, c₂ = specific heat of coffee = 4.2 J/g °C, T₃ = initial temperature of coffee = 85 °C and T₂ = final temperature of coffee.

So, Q = -Q'

m₁c₁(T₂ - T₁) = -m₂c₂(T₂ - T₃)

Making T₂ subject of the formula, we have

m₁c₁T₂ - m₁c₁T₁ = -m₂c₂T₂ + m₂c₂T₃

m₁c₁T₂ + m₂c₂T₂ = m₂c₂T₃ + m₁c₁T₁

(m₁c₁ + m₂c₂)T₂ = m₂c₂T₃ + m₁c₁T₁

T₂ = (m₂c₂T₃ + m₁c₁T₁)/(m₁c₁ + m₂c₂)

substituting the values of the variables into the equation, we have

T₂ = (180 g × 4.2 J/g °C × 85 °C + 45 g × 0.88 J/g °C × 24 °C )/(45 g × 0.88 J/g °C + 180 g × 4.2 J/g °C)

T₂ = (64260 J + 950.4 J)/(39.6 J/°C + 756 J/°C)

T₂ = 65210.4 J/795.6 J/°C

T₂ = 81.96 °C

T₂ ≅ 82 °C
