This is a three part problem I need help in figuring out pleaseI
n each of the questions below you are going to determine a different type of balanced equation for the same reaction. Make sure your equations have the lowest whole number coefficients possible. Indicate the physical states of the reactants and products. Refer to Solubility rules as necessary.
Barium sulfate is used when X-rays of the gastrointestinal tract are made. Barium sulfate can be prepared by reacting barium chloride with dilute sulfuric acid. From this description, determine the balanced formula unit equation. Enter your answer as the sum of the coefficients of all of the species. Make sure your equation has the lowest whole number coefficeints possible. Refer to solubility rules as necessary.
In water purification small solid particles are often ``trapped'' as aluminum hydroxide precipitates and fall to the bottom of the sedimentation pool. Aluminum sulfate reacts with calcium hydroxide (from lime) to form aluminum hydroxide and calcium sulfate. Determine the total ionic equation for the reaction stated. Again, enter your answer as the sum of the coefficients.
Bones are mostly calcium phosphate. Calcium chloride reacts with potassium phosphate to form calcium phosphate and potassium chloride. From this information, write the balanced net ionic equation. Answer as the sum of the coefficients yet again.
Sure, let's solve these three problems step-by-step:
1. Reaction between Barium chloride and dilute sulfuric acid to form Barium sulfate:
First, we need to write the balanced formula unit equation, indicating the physical states of the reactants and products.
The balanced formula unit equation is:
BaCl2(aq) + H2SO4(aq) → BaSO4(s) + 2HCl(aq)
2. Reaction between Aluminum sulfate and Calcium hydroxide to form Aluminum hydroxide and Calcium sulfate:
Next, we need to determine the total ionic equation for the reaction.
The total ionic equation is:
2Al3+(aq) + 3SO4^2-(aq) + 3Ca2+(aq) + 6OH^-(aq) → 2Al(OH)3(s) + 3CaSO4(s)
Note: In the total ionic equation, all the soluble ionic compounds are split into their respective ions.
3. Reaction between Calcium chloride and Potassium phosphate to form Calcium phosphate and Potassium chloride:
Lastly, we need to write the balanced net ionic equation.
The balanced net ionic equation is:
3Ca2+(aq) + 2PO4^3-(aq) → Ca3(PO4)2(s)
Note: In the net ionic equation, spectator ions (ions that remain unchanged in the reaction) are removed.
I hope this helps! Let me know if you have any further questions.
To find the balanced formula unit equation for the reaction between barium chloride and dilute sulfuric acid, we need to follow these steps:
Step 1: Write the chemical formula of barium chloride and dilute sulfuric acid.
- Barium chloride has the formula BaCl2.
- Sulfuric acid has the formula H2SO4.
Step 2: Identify the products of the reaction.
- When barium chloride reacts with sulfuric acid, it forms barium sulfate (BaSO4) and hydrochloric acid (HCl).
Step 3: Write the balanced formula unit equation.
- The balanced equation is: BaCl2 + H2SO4 → BaSO4 + 2HCl
- This equation shows that barium chloride reacts with sulfuric acid to form barium sulfate and hydrochloric acid.
For the second question, to find the total ionic equation for the reaction between aluminum sulfate and calcium hydroxide, follow these steps:
Step 1: Write the chemical formula of aluminum sulfate and calcium hydroxide.
- Aluminum sulfate has the formula Al2(SO4)3.
- Calcium hydroxide has the formula Ca(OH)2.
Step 2: Identify the products of the reaction.
- When aluminum sulfate reacts with calcium hydroxide, it forms aluminum hydroxide (Al(OH)3) and calcium sulfate (CaSO4).
Step 3: Write the total ionic equation.
- The total ionic equation separates all soluble compounds into their individual ions. The soluble compounds in this reaction are aluminum sulfate, calcium hydroxide, and calcium sulfate.
- The balanced total ionic equation is: 2Al3+ + 3SO4^2- + 3Ca2+ + 6OH- → 2Al(OH)3 + 3Ca^2+ + 3SO4^2-
For the third question, to find the balanced net ionic equation for the reaction between calcium chloride and potassium phosphate, follow these steps:
Step 1: Write the chemical formula of calcium chloride and potassium phosphate.
- Calcium chloride has the formula CaCl2.
- Potassium phosphate has the formula K3PO4.
Step 2: Identify the products of the reaction.
- When calcium chloride reacts with potassium phosphate, it forms calcium phosphate (Ca3(PO4)2) and potassium chloride (KCl).
Step 3: Write the balanced net ionic equation.
- The net ionic equation removes spectator ions, which are ions that do not participate in the reaction. In this case, the spectator ions are potassium (K+) and chloride (Cl^-).
- The balanced net ionic equation is: 3Ca^2+ + 2PO4^3- → Ca3(PO4)2
