The complete equation to following equation to make a double replacement reaction is: Na2SO4 + BaCl2 = BaSO4 + 2NaCl.

<h3>What is a double displacement reaction.</h3>

A double displacement reaction is the reaction that involves the replacement of two elements.

According to this question, barium sulfate (BaSO4) and sodium chloride are produced from the chemical equation given.

This clearly suggests that Sodium sulfate is the missing reactant, hence, the complete equation to following equation to make a double replacement reaction is:

Na2SO4 + BaCl2 = BaSO4 + 2NaCl.

Copper has a density of 8.96 g/cm3. If 75.0 g of copper is added to 50.0 mL of water in a graduated cylinder, to what volume rea
Tcecarenko [31]

Answer:

The answer to your question is    Final volume = 58.37 ml

Explanation:

Data

density = 8.96 g/cm³

mass = 75 g

volume of water = 50 ml

Process

1.- Calculate the volume of copper

  Density = mass / volume

Solve for volume

  Volume = mass / density

Substitution

  Volume = 75/8.96

Simplification

  Volume = 8.37cm³    or 8.37 cm³

2.- Calculate the new volume of water in the graduated cylinder

  Final volume = 50 + 8.37

  Final volume = 58.37 ml
