A feedback mechanism that increases respiration rate to exhale more co2 would be:_________

Arisa [49]

As your body needs more oxygen during exercising and produces more carbon dioxide, this might result in a high respiratory rate.

During exercise, your breathing may occur 3–4 times more frequently. Hyperpnea, or rapid, deep breathing, is the body's natural response to increased carbon dioxide generation. The pace of breathing increases along with the blood's concentration of carbon dioxide. The pH of the blood changes dramatically as carbon dioxide levels rise. The chemoreceptors in the medulla oblongata, a part of the hindbrain that controls respiration, detect this shift. To expel the additional carbon dioxide and breathe in more oxygen, the respiratory center speeds up breathing.

Sodium carbonate can be made by heating sodium bicarbonate: 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) At 25°C, for this reaction,

insens350 [35]

Answer:

401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.

Explanation:

The expression for the standard change in free energy is:

$\Delta G=\Delta H-T\times \Delta S$

Where,

$\Delta G$ is the change in the Gibbs free energy.

T is the absolute temperature. (T in kelvins)

$\Delta H$ is the enthalpy change of the reaction.

$\Delta S$ is the change in entropy.

Given at:-

Temperature = 25.0 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (25.0 + 273.15) K = 298.15 K

$\Delta H$ = 128.9 kJ/mol

$\Delta G$ = 33.1 kJ/mol

Applying in the above equation, we get as:-

$33.1=128.9-298.15\times \Delta S$

$-29815\Delta S=-9580$

$\Delta S=-9580$ = 0.32131 kJ/Kmol

So, For reaction to be spontaneous, $\Delta G$

Thus, For minimum temperature:-

$\Delta H-T\times \Delta S=0$

$128.9-T\times 0.32131=0$

$T=\frac{128.9}{0.32131}=401.17\ K$

<u>Hence, 401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.</u>

Linear molecule with two domains

Explanation:

The describe geometry of the substance fits that of a linear molecule with two domains.

This description is based on the VSEPR i.e Valence Shell Electron Pair repulsion(VSEPR) model. It states that if an atom is bonded by two or more kinds of atoms the shape is determined by the geometry of the bonds around the central atom.

The electron domain is the number of lone pairs of electron around an atom.

Here in CO₂:

there are two lone pairs and the oxygen atoms are in a 180° linear shape around the central carbon atom. The bond is made up of two O⇔C structure.
