Answer:

<em><u>an abandoned field, a cooling lava flow, a valley under a glacier, and an unused farm</u></em>

Explanation:

Primary succession happens in a place where there is no soil cover or it is removed.

an abandoned field- Secondary; because there is cover of soil left, even if vegetation is removed.  

a cooling lava flow- Primary; volcanic events lead to loss of soil layer, so this would lead to primary succession  

a valley under a glacier- Primary; retreating glaciers are lead to primary succession  

an unused farm-Secondary; the soil cover is still present

a burnt forest- Secondary; soil cover is still left for vegetation to start over again

a deserted mine- Primary; because there would be barren rocks left, so soil would be formed by pioneer species first.

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.

In this stoichiometry problem, determine the limiting reactant.
Tanya [424]

Answer:

Limiting reactant is NiSO₄

Explanation:

The reaction of aluminum metal with aqueous nickel(II)  sulfate to produce aqueous aluminum sulfate and nickel is:

2 Al(s) + 3 NiSO₄ → Al₂(SO₄)₃ + 3 Ni  

<em>That means 2 moles of Al react with 3 moles of nickel sulfate.</em>

<em />

Moles of Al and NiSO₄ are:

Al: 108g × (1mol / 26.98g) = 4.00 moles of Al

NiSO₄: 464g × (1mol / 154.75g) = 3.00 moles of NiSO₄

For a complete reaction of aluminium there are necessary:

4.00mol Al ₓ ( 3 moles NiSO₄ / 2 moles Al) = 6 moles of NiSO₄

As you have just 3.00 moles of NiSO₄, the <em>limiting reactant is NiSO₄</em>
