How does the density of air affect local weather patterns?

Chemistry
1 answer:
JulijaS [17]3 years ago
5 0
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.

Limiting Reactant
liraira [26]

Answer:

(1) Cl₂ is the limiting reactant.

(2) 8.18 g

Explanation:

  • 2Na(s) + Cl₂(g) → 2NaCl(s)

First we <u>convert the given masses of reactants into moles</u>, using their <em>respective molar masses</em>:

  • Na ⇒ 12.0 g ÷ 23 g/mol = 0.522 mol Na
  • Cl₂ ⇒ 5.00 g ÷ 70.9 g/mol = 0.070 mol Cl₂

0.070 moles of Cl₂ would react completely with (2 * 0.070) 0.14 moles of Na. There are more Na moles than that, so Na is the reactant in excess while Cl₂ is the limiting reactant.

Then we <u>calculate how many moles of NaCl are formed</u>, <em>using the limiting reactant</em>:

  • 0.070 mol Cl₂ * \frac{2molNaCl}{1molCl_2} = 0.14 mol NaCl

Finally we <u>convert NaCl moles into grams</u>:

  • 0.14 mol NaCl * 58.44 g/mol = 8.18 g

If heat transfers from the system (solute) to the surroundings (solvent), then AH is
balu736 [363]

Answer:

B) exothermic.

Explanation:

Hello!

In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.

In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:

B) exothermic .

Best regards!
