Answer:

79.2 mL

Explanation:

Step 1: Given data

  • Density of chloroform (ρC): 1.49 g/mL
  • Density of ethyl alcohol (ρE): 0.789 g/mL
  • Volume of ethyl alcohol (VE): 150 mL

Step 2: Calculate the mass corresponding to 150 mL of ethyl alcohol

We will use the definition of density.

ρE = mE/VE

mE = ρE × VE

mE = 0.789 g/mL × 150 mL = 118 g

We want the mass of chloroform to match the mass of ethyl alcohol. Then, mC = mE = 118 g

Step 3: Calculate the volume corresponding to 118 g of chloroform

We will use the definition of density.

ρC = mC/VC

VC = mC/ρC

VC = 118 g/ (1.49 g/mL) = 79.2 mL

Why does liquid exerts pressure​
andriy [413]

Answer:

The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

Define Acid dissociation constant constant
stiks02 [169]

Answer:

An acid dissociation constant, K a, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction ↽ − − ⇀ − + + known as dissociation in the context of acid–base reactions.

21. Apply Concepts Classify each reaction and balance the
adell [148]

The reactions are in order which includes combustion reaction, Hydration reaction, oxidation reaction, and displacement reaction.

a) A combustion reaction is a chemical reaction between a fuel and an oxidant where heat is released. The combustion reaction example is given below. It is a balanced chemical reaction.

2C₃H₆(g) + 9O₂(g) --------> 6CO₂(g) + 6H₂O(g)

b. A hydration reaction is a chemical reaction in which a molecule of water is added to another molecule. Here Aluminum oxide is added to water to form aluminum hydroxide.

4Al₂O3(s) + 6H₂O(l)------> 2Al(OH)3(s)

c. When a metal reacts with oxygen, the metal forms an oxide. Oxide is a compound of metal and oxygen. Here lithium metal reacts with oxygen to form lithium oxide.

2Li(s) + O₂(g)-----> Li₂O(s)

d. A displacement reaction is one in which a more reactive element displaces a less reactive element from a compound. Here Zinc is more reactive than silver, so silver was displaced to form Zinc Nitrate.

Zn(s) + 2AgNO₃(aq) -----> 2Ag(s) + Zn(NO₃)₂(aq)
