Answer: the answer is 0.32 meters but
Explanation: The prefix “centi-” means “one-hundredth,” so a centimeter equates to 1/100 of a meter. This means that converting from centimeters to meters always involves dividing by 100. Similarly, converting from meters to centimeters always involves multiplying by 100. hope it helps:)
Okay its like whipping sweetheart it goes cold to hot from liquid to a solid substance so you would need a constant heat
Answer:
<u>The last statement describes the correct inozation of water:</u>
Pure water at 25ºC:
- self-ionizes to form an equilibrium system in which:
Explanation:
It has been proven that <em>pure wate</em>r slightly conducts electricity. This fact, explained by the Arrhenius model of acids, would mean that pure water contains ions.
Since such ions are spontaneoulsy produced by the water molecules, this phenomenum is called <em>self-ionization of water</em>.
The equilibrium equation that represents the self-ionization of water is:
The expression for the equilibrium constant is:
As per the stoichiometry:
The equilibrium constant for the self-ionization of water has been determined at several temperatures. At 25ºC it is equal to 1.0×10⁻¹⁴.
Then by solving the equation you can find the concentrations of the ions:
Hence, we have proved that pure water self-ionizes to form an equilibrium system in which:
Given the empirical formula, the molecular formula that has a mass of 214.8g is C₁₀H₁₅O₅
<h3>Empirical & ,molecular formulae </h3>
From the question, we are to determine the molecular formula
From
Molecular formula = (Empirical formula)n
Where
From the given information,
Empirical formula is C₂H₃O
Therefore, Empirical formula mass = (12×2) + (1×3) + (16)
Empirical formula mass = 24 + 3 + 16
Empirical formula mass = 40 g
Then,
n = 5.37
n ≅ 5
Therefore,
Molecular formula = (C₂H₃O)₅
Molecular formula = C₁₀H₁₅O₅
Hence, given the empirical formula, the molecular formula that has a mass of 214.8g is C₁₀H₁₅O₅
