Answer: CaCl+LiCO_3\rightarrow CaCO_3+LiCl

Explanation: A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

In the given reaction:

The molecular formula of Lithium carbonate is incorrect as lithium forms a monovalent cation but carbonate is a divalent polyatomic ion. Thus in order to form a neutral ionic compound two atoms of Li^+ must combine with one CO_3^{2-} to give Li(CO_3)_2

If 9.9L of helium are in a tire at 303k,how many liters will be present at 403k if the pressure is held constant.
Slav-nsk [51]

Answer:

Final volume, V2 = 13.18 Liters

Explanation:

<u>Given the following data;</u>

Initial volume = 9.9 L

Initial temperature = 303 K

Final temperature = 403 K

To find the final volume, we would use Charles law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles' law is given by the formula;

VT = K

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}

Where;

  • V1 and V2 represents the initial and final volumes respectively.
  • T1 and T2 represents the initial and final temperatures respectively.

\frac{V1}{T1} = \frac{V2}{T2}

Making V2 as the subject formula, we have;

V_{2}= \frac{V1}{T1} * T_{2}

V_{2}= \frac{9.9}{303} * 403

V_{2}= 0.0327 * 403

<em>Final volume, V2 = 13.18 Liters</em>

What is the percent yield if 107.50 g NH3 reacts with excess O2 according to the
Maksim231197 [3]

Answer:

81.59%

Explanation:

  • 4NH₃ + 5O₂ → 4NO + 6H₂O

First we <u>convert 107.50 g of NH₃ into moles</u>, using its <em>molar mass</em>:

  • 107.50 g NH₃ ÷ 17 g/mol = 6.32 mol NH₃

Now we <u>calculate how many moles of NO would have been formed by the complete reaction of 6.32 moles of NH₃</u>:

  • 6.32 mol NH₃ * \frac{4molNO}{4molNH_3} = 6.32 mol NO

Then we <u>convert 6.32 moles of NO to grams</u>, using its <em>molar mass</em>:

  • 6.32 mol NO * 30 g/mol = 189.60 g NO

Finally we <u>calculate the percent yield</u>:

  • 154.70 g / 189.60 g * 100% = 81.59%
