3 0

Answer:

a) 0.0265M

b) 8.35×10^-4M

c) 9.833×10^-8M

Explanation:

First we must write down the equation of each reaction. After identifying the insoluble precipitate, we go ahead to write down the expression for its solubility product. If the solubility product of the compound is known, the concentration of the precipitating agent can now be calculated from the available information in the question.

sashaice [31]

Answer:

B

Explanation:

The letter in this energy profile diagram of an exothermic change that signifies energy is B;

  • An exothermic reaction is one in which heat is liberated to the surroundings.
  • The surrounding becomes hotter at the end of the change.
  • B is the enthalpy change of the reaction
  • A is the activation energy
  • C is the reactant
  • D is the product

Why is time plotted on the x axis and distance on the y axis?
SIZIF [17.4K]

Answer:

Because time is independent of distance, and distance is dependent of time.

Explanation:

Usually, on any graph, the independent variable is plotted on the x-axis and the dependent variable is plotted on the y-axis. Because of this, time, which is independent (time happens regardless of any other factor), is on the x-axis while distance, which is the dependent variable (can only take place in time), is on the y-axis.

A glass column is filled with mercury and inverted in a pool of mercury. The mercury column stabilizes at a height of 729 mm abo
harkovskaia [24]

The atmospheric pressure will be:

The pressure of the atmosphere resulting from the mercury column is 0.959 atm

What is atmospheric pressure?

The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.

Given: Height of mercury column = 729 mm Hg

To find: The pressure of the atmosphere

Calculation:

The atmospheric column resulting from the mercury column is calculated as follows:

1 atm =760 mm Hg

So, we can convert the 729 mm Hg to atm, and we get

Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm
