Answer:

Answer in explanation

Explanation:

Gases are expected to behave as ideal gases at particular temperature and pressure know as the S.T.P.

At a temperature of 273k and a pressure of 1atm, it is expected that a mole of a gas will occupy a volume of 22.4L. Now, a particular student measured the pressure of a gas at 425K, it is expected that the pressure is different from the one that is supposed to be observed at STP and thus , the measures quite differently

Les étapes nous permettant de sentir une tarte aux pommes
Dmitry [639]

Answer:

L'ordre correct est le suivant;

1. Les cils olfactifs capturent les molécules chimiques odorantes

2. Le signal des molécules chimiques est transformé en impulsions nerveuses

3. L'influx nerveux est transféré au cerveau par le nerf olfactif au bulbe olfactif du cerveau antérieur

4. Les odeurs sont perçues

Explanation:

Pour sentir la pomme, l'air autour de la pomme est inhalé rapidement pour aider les produits chimiques odorants à entrer dans la cavité nasale.

La cavité nasale a des cellules spéciales qui sont réceptives aux produits chimiques odorants, qui envoient un message au cerveau lors de la liaison au produit chimique par le nerf olfactif. Lorsque le message arrive au bulbe olfactif du cerveau antérieur, il est analysé et l'odeur est identifiée et / ou reconnue.

Par conséquent, l'ordre correct est le suivant;

1. 1. Les cils olfactifs captent les molécules chimiques odorantes

2. 2. Le signal des molécules chimiques est transformé en impulsions nerveuses

3. 4. L'influx nerveux est transféré au cerveau par le nerf olfactif au bulbe olfactif du cerveau antérieur

4. 3. Les odeurs sont perçues.

The density of helium is 0.17 g/L. What Is the mass of helium in a 5.4 L helium balloon? (2 sig figs) *
ioda

Answer:

The correct answer is 0.92 g

Explanation:

The density is defined as the mass per unit of volume:

Density= mass/volume

From the data provided:

volume= 5.4 L

density= 0.17 g/L

Thus, to calculate the mass of helium:

mass= density x volume = 0.17 g/L x 5.4 L= 0.918 g ≅ 0.92 g

If the pOH of a nitric acid (HNO3) solution is measured as 11, what is the concentration of HNO3 solution?
Illusion [34]

1 gram of HNO3 will be equal to 1/63.01 moles. Therefore, we can say that 1 liter of Nitric acid contains 15.6976 moles or in other words molarity of 70% (w/w) Nitric acid is equal to 15.6976 M.

Known values  

Molecular weight of HNO3 63.01 g/mole

Concentration of Nitric acid 70% (% by mass, wt/wt)
