The physical changes are:

  • condensation of water vapors
  • carving wax
  • slicing a banana tearing
  • aluminum foil

The chemical changes are:

  • bleaching hair
  • silver tarnishing,
  • frying an egg, and
  • burning paper

<h3>What are physical and chemical changes?</h3>

Physical changes are changes which occur in a substance which may alter the physical properties of the substance but does not affect the chemical properties of the substance. Physical changes are easily reversible

In physical changes, no new substances are formed. Example of a physical change is the melting of ice or candle wax.

Chemical changes are changes which alter the chemical properties of a substance and in which new substances are formed. Example of chemical changes are; the rusting of iron, bleaching hair silver tarnishing, frying an egg, and burning paper.

Chemical changes are not easily reversible.

In conclusion, physical changes do not produce new substances while chemical changes produce new substances.

Rearrange the following equation and solve for x when the hydrogen ion concentration is 0.01 M. pH=4+logx (Recall that pH=−log[H
bezimeni [28]

Answer:

x = 1 x 10⁻²

Explanation:

Since the pH is the same in both cases, the two expressions for pH can be set equal to each other:

pH = 4 + log(x) = -log[H⁺]

The hydrogen ion concentration ([H⁺]) is 0.01 M, so this value can be substituted in the equation:

4 + log(x) = -log(0.01)

4 + log(x) = 2

log(x) = -2

x = 10⁻²

mezya [45]

The given question is incomplete. The complete question is:

A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.

Answer: Concentration of the chemist's barium chloride solution is 1.20 mol/L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times }{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of BaCl_2(solute) = \frac{\text {given mass}}{\text {Molar Mass}}=\frac{110g}{208g/mol}=0.529mol

Now put all the given values in the formula of molality, we get

Molality=\frac{0.529\times 1000}{440ml}=1.20mole/L

Therefore, the molarity of solution is 1.20 mol/L
