Answer:
To measure heat, you divide the change in temperature of a sample of water by the mass of the water.
Data Given:
[H⁺] = 3.16 × 10⁻⁷ M
To Find:
pH = ?
Solution:
As we know that,
pH = -log [H⁺]
Putting values,
pH = -log (3.16 × 10⁻⁷)
pH = 6.50
Kind of Solution:
As we know, when pH of a solution is equal to 7, it is Neutral. When less than 7, its Acidic and when greater than 7, it is Basic. As this solution has pH 6.50, which is less than 7, so it is slightly Acidic in Nature.
Two molecules of HBr collide and then form H2 and Br2. During the collision, the bonds in the HBr molecules are <span>(3) formed as energy is absorbed.</span>
Answer:
Explanation:
Hello,
In this case, we use the boiling point elevation colligative property equation for both ethanol and carbon tetrachloride as shown below:
Now, since both the boiling point and the concentration of the solutions are equal, we solve a 2x2 system of lineal equations:
Subtracting the equations one obtains the molality (concentration):
Finally, solving for the boiling temperature of the solution one obtains:
Best regards.
Answer:
732.0601 mmHg
Explanation:
Given data:
Pressure = 97.6 KPa
Given pressure in mmHg = ?
Solution:
Kilo pascal and millimeter mercury both are units of pressure.
Kilo pascal is denoted as "KPa"
Millimeter mercury is denoted as " mmHg"
Kilo pascal is measure of force per unit area while also define as newton per meter square.
It is manometric unit of pressure. It is the pressure generated by column of mercury one millimeter high.
Conversation of kilopascal to mmHg:
97.6 × 7.501 = 732.0601 mmHg
