Which statements describe aspects of what causes wind to blow? Wind is caused by differences in air pressure. Wind moves from lo

w pressure areas to high pressure areas. Differences in air pressure are due to unequal heating. Differences in air pressure are caused by oceans. Wind is caused by the Coriolis effect.

Answer:

The Correct Answer is A and C.

Explanation:

  • The wind is the movement of air, the movement of air is happened by the difference in pressure.
  • A difference in air pressure is what causes the wind to blow. Difference in pressure is happened by the uneven heating of the earth's surface.
  • The wind is normally moving air from a high air pressure place to a low air pressure place.
  • The greater the difference in air pressure the stronger the wind blow.

According to the balanced chemical equation
Nadusha1986 [10]

Answer:

A) 15.5 mL

Explanation:

Given, Mass of oxalic acid = 0.3500 g

Molar mass of oxalic acid = 90.03 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{0.3500\ g}{90.03\ g/mol}

Moles\ of\ oxalic\ acid= 0.0038876\ mol

According to the given reaction:

5H_2C_2O_4_{(aq)}+2MnO_4^-_{(aq)}+6H^+_{(aq)}\rightarrow 10CO_2_{(g)}+2Mn^{2+}_{(aq)}+8H_2O_{(l)}

5 moles of oxalic acid react with 2 moles of potassium permanganate

Thus,

1 mole of oxalic acid react with 2/5 moles of potassium permanganate

0.0038876 mole of oxalic acid react with \frac {2}{5}\times 0.0038876 moles of potassium permanganate

Moles of potassium permanganate = 0.001555 moles

Also, considering:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity = 0.100 M

So,  

0.100=\frac{0.001555}{Volume\ of\ the\ solution(L)}

Volume = 0.01555 L

Also, 1 L = 1000 mL

So, volume = 15.5 mL
