Lastly, Snape thinks we should try one more calculation. What is the retention factor if the distance traveled by the solvent fr

ont is 2.0 cm, and the distance the ion is from the solvent front is 0.20 cm? Hint: Be careful with how Snape worded this question.

Answer:

0.1 is the retention factor.

Explanation:

Distance covered by solvent ,d_s= 2.0 cm

Distance covered by solute or ion,d = 0.20 cm

Retention factor(R_f) is defined as ratio of distance traveled by solute to the distance traveled by solvent.

R_f=\frac{d}{d_s}

R_f=\frac{0.20 cm}{2.0 cm}=0.1

0.1 is the retention factor.

Carbon monoxide and chlorine combine in an equilibrium reaction to produce the highly toxic product, phosgene (COCl2 ) CO(g) Cl2
Anuta_ua [19.1K]

Answer:

Reaction will proceed towards forward direction.

Explanation:

Balanced reaction: CO+Cl_{2}\rightleftharpoons COCl_{2}

Reaction quotient (Q_{c}) for this reaction is represented as:

                                         Q_{c}=\frac{[COCl_{2}]}{[CO][Cl_{2}]}

Here, [CO] = [Cl_{2}] = 0.010 M and [COCl_{2}] = 0.070 M

                              So, Q_{c}=\frac{0.070}{(0.010)^{2}} = 700

As Q_{c} > K_{c} therefore reaction will proceed towards forward direction i.e. moreCOCl_{2} will be produced.

LenKa [72]
<h3><u>Answer;</u></h3>

exceeds evaporation over land

Precipitation<u> exceeds evaporation over land </u>

<h3><u>Explanation;</u></h3>
  • <em><u>In order to maintain earths water balance, evaporation exceeds precipitation over oceans but precipitation exceeds evaporation over land.</u></em>
  • Water evaporates into the atmosphere from the ocean and to a much lesser extent from the continents. Winds transport this moisture-laden air, often great distances, until conditions cause the moisture to condense into clouds and to precipitate and fall.
  • Most precipitation originates by evaporation from the oceans. Over time, water evaporated from the oceans is replenished by inflow of freshwater from rivers and streams.

H2 + CaCl2 --&gt; 2HCl + Ca How many grams of HCl are made when 2.93 g of<br><br> Ca are made?
Sholpan [36]

Answer:

H2 + CaCl2 -> 2HCl + Ca

How many grams of HCl are made when 2.93 g of

Ca are made?

Explanation:

From the given balanced chemical equation, it is clear that:

2mol. of HCl and 1mol. of Ca are produced.

2mol. of HCl weighs --- 73.0g

1mol. of Ca weighs --- 40.0g

Hence,

73.0g of HCl and 40.0g of Ca are produced.

When 2.93g of Ca is produced then, how many grams of HCl will be produced?

=> 2.93g Ca * \frac{73.0g HCl}{40.0g Ca} \\=5.35g HCl

Hence, 5.35g of HCl is formed.
