Which gas is not known as green house gas

1 answer:

6 0

Carbon dioxide is a main greenhouse gas, found in car exhaust pipes. Methane and nitrous oxide is another type of greenhouse gas. Oxygen is the only clean gas out there because we need it to survive. Therefore, the only gas that is not a greenhouse gas is (c) oxygen.

What is the density of a piece of metal that has a mass of 75.8g and a volume of 7.09

Mice21 [21]

Answer:

10.69g/cm^3 or 0.0106kg/m^3

Explanation:

10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.

0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.

So technically since you questions incomplete, the equation for measuring density is P= m/v

P= rho (density)

m= mass

v= volume

This set contains the spectra of benzil, biphenyl, and bibenzyl, three compounds used in the melting point experiment. Using you

murzikaleks [220]

Answer:

Spectrum 1- Biphenyl

Spectrum 2 - Benzil

Spectrum 3 - Bibenzyl

Explanation:

<u>For Benzil: </u>

<u> </u>The Spectrum - 2 shows this compound.The C=O and C-H bond stretching observed at following values.

$C=O \,at\,1657cm^{-1}$

$C=H \,at\,3063cm^{-1}$

<u> For Biphenyl: </u>

<u> </u>Spectrum - 1 shows this compound.

There are stretching vibrations from $3061, 3032\,and \,1597 -1428cm^{1}$ due to C-H stretching and C-C stretching respectively of aromatic ring only.

<u>For Bibenzyl: </u>

Spectrum - 3 shows this compound

There are stretching vibrations at $3057,3026 and 1598 - 1449cm^{-1}$ due to C-H stretching and C-C stretching of aromatic ring.

Along with this, stretching vibrations at $2943 - 2917 cm^{-1}$ due to C-H of alkyl.

The mussel shells are eroding because the ocean is too acidic. More acidic oceans dissolve CaCO3 faster and change them into HCO

ahrayia [7]

This problem is providing information about possible causes whereby mussel shells are being eroded due to the acidity in the ocean. In such a way, it claims that more acidic oceans dissolve calcium carbonate in a faster way and produce hydrogen carbonate ions, and thus, a feasible explanation is required as well as a hypothesis according to the following choices:

a. Lower CO₂; this reduces the H₂CO₃ and increases the pH.

b. Add CO₃²⁻: this will add base and increase its concentration.

c. Add Ca²⁺: this will increase the precipitation rate of calcium carbonate (correct choice).

<h3>Equilibrium equations:</h3>

At first instance, we should recall the equilibrium equations that take place when acidic oceans dissolve calcium carbonate in a faster way:

$CaCO_3(s)\rightleftharpoons Ca^{2+}(aq)+CO_3^{2-}(aq)\\\\CO_3^{2-}(aq)+H^+(aq)\rightleftharpoons HCO_3^-(aq)$

$CO_2(g)+H_2O(l)\rightleftharpoons H_2CO_3(aq)$

<h3>Shifts from equilibrium:</h3>

Where we can see that the first choice is thoroughly discarded as the addition of CO₂ actually increases the ionizable carbonic acid (acidity). Moreover, the addition of CO₃²⁻ may also lead to the formation of more protons-releasing carbonic acid which also contributes to the acidity of the ocean.

<h3>Hypothesis:</h3>

Thereby, the correct condition that, for sure, contributes to the preservation of mussel shells will be the addition of Ca²⁺ and the hypothesis will be that it shifts the equilibrium towards the formation of more CaCO₃, the active compound in these shells.

During the action potential of a neuron, which ion is primarily crossing the membrane during the depolarization phase, and in wh

Zigmanuir [339]

Answer:

C. Na⁺ is entering the cell.

Explanation:

In the depolarization phase, the permeability of sodium ions (Na⁺) increases, allowing a large flow of sodium ions to enter the cell through the membrane by simple diffusion.

This process causes intracellular liquids to be <u>positively</u> charged due to the large amount of cations.
