Answer:
Freezing and boiling point
Explanation:
A liquid form of any substance is an intermediate form between the solid form and the gaseous form.
Decreasing the temperature of liquid water according to the phase diagram of would freeze it and we would have a phase change from liquid to solid (ice) at the freezing point of water.
Similarly, heating water to its boiling point would evaporate water and we would have a phase change from liquid to gas (water vapor).
Therefore, liquid water exists between its freezing and boiling point.
Answer:
Density = 0.0007667 Kg/cm³
Explanation:
Given the following data;
Mass of empty beaker = 0.50 kg
Volume of solution = 300 cm³
Mass of glass+solution = 730 g
To find the density of the solution in the glass;
First of all, we would convert the value in grams to kilograms.
Conversion:
1000 grams = 1 kg
730 = X kg
Cross-multiplying, we have;
X = 730/1000 = 0.73 kg
Next, we would determine the mass of the solution.
Mass of solution = Mass of glass+solution - Mass of empty beaker
Mass of solution = 0.73 - 0.50
Mass of solution = 0.23 kg
Lastly, we would solve for the density of the solution;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the formula, we have;
Density = 0.0007667 Kg/cm³
Answer:
- Acetic acid (CH₃COOH) and hydronium ion (H₃O⁺)
Explanation:
Hello,
In this case, based on the acid-base theory which states that acids are known as H⁺ donors, if we consider the direct reaction:
It is clear that the acetic acid is the first H⁺ donor as it losses one H⁺ to turn into the acetate ion. Moreover, if we consider the inverse reaction:
It is also clear that the hydronium ion is the second H⁺ donor as it losses one H⁺ to turn into water.
Best regards.
