The amount of the product in grams, formed from the limiting reactant is the  theoretical yield

<u>Explanation:</u>

In a chemical reaction when the limiting agent is completely reacted and the product obtained is termed as Theoretical yield. The amount of product yield that is attained through a complete reaction of the limiting agent is the theoretical yield.  Grams or moles is used for expressing theoretical yield.

This is calculated form the limiting agent in a complete chemical reaction which is balanced.  If a chemical reaction is unbalanced, it should be first balanced to find the theoretical yield. Then, the limiting agent must be found. When the limiting agent is small in quantity, the reaction cannot be completed once the limiting agent is fully used and exhausted.

When an aqueous solution of strontium chloride is added to an aqueous solution of potassium sulfate, a precipitation reaction oc
Georgia [21]

Answer:

2Cl^{-}_{(aq)}  + 2K^{-} _{(aq)}  = 2KClx_{(aq)}

Explanation:

The reaction is a precipitation reaction. In other words, the two aqueous solutions react to give the solid salt, potassium chloride (KCl) in this case.

SrCl_{2} _{(aq)}  + K_{2}SO_{4} _{(s)} = SrSO_{4} _{(aq)} + 2KCl_{(s)}

Because the reaction product is a solid, the net ionic equation can be written as:

2Cl^{-}_{(aq)}  + 2K^{-} _{(aq)}  = 2KClx_{(aq)}

This is the resultant equation after removing spectator ions: sulfate and strontium.

what is the freezing point of a 0.195m aqueous solution of K2S? (Report amount to three decimal points)
Solnce55 [7]
The freezing point depression of water is 1.86°C/m.kg 
<span>K2S dissociates: </span>
<span>K2S ↔ 2K+ + S 2- </span>
<span>1mol K2S will produce 3 mol of ions. </span>
<span>Therefore in the freezing point equation: i = 3 </span>
<span>Depression of freezing point = Kf * i* m </span>
<span>Depression of freezing point = 1.86*3*0.195 </span>
<span>Depression of freezing point = 1.088°C </span>
<span>The solution will freeze at - 1.088°C </span>

How would you measure the pH of a coloured substance such as red ink.why?
earnstyle [38]
There are 3 possible ways of determining pH.
1. A pH meter, 2. Litmus paper/ pH test strips or 3. Titrations. 

1. A pH meter works by sending a small electric current through the solution. An electrical current can only be created if there are free-moving particles such as H+ ions from an acid or OH- ions from a base. The pH meter can determine the pH by how high the conductivity is. 

2. Litmus Paper or pH test strips are strips that turn a specific colour under a specific pH. This colour can then be compared to a colour chart which will tell you the pH. The downfall of this method is that the red ink will stain the strip and you will be unable to get an accurate reading. 

3. A titration is the best method, if done properly, for determining pH.

Why does 5060 have three significant figures?
Morgarella [4.7K]
<h2>5060 have three significant figures : Explanation given below </h2>

Explanation:

Significant figures

The significant figures (also known as the significant digits and decimal places) of a number are digits that possess certain  meaning .

It  includes all digits except: zeros

Rules to find significant figures

1.All non-zero digits are considered significant. For example, 23  has two significant figures.

2.Zeros in between two non-zero digits are significant: like in 202.1201  has seven significant figures.

3.Zeros to the left of the significant figures are not significant. For example, .000021 has two significant figures, zeros have no value .

4.Zeros to the right of the significant figures are significant.

That is the reason in number 5060 , it has 3 significant figures .
