They like cheese because it is easy to eat and it tases really good
Answer:
False
Explanation:
Amplitude does not affect wavelength
The given molarity of sodium hydroxide solution = 2.0 M
The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH
Converting 65 mL to L:
Calculating the moles of NaOH in the final solution:
Finding out the volume of 2.0 M solution taken to prepare the final solution:
Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.

Answer:</h3>
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
<h3>
Explanation:</h3>
We are required to complete the chemical equation given;
strontium carbonate + sulfuric acid → ??
- We know that, carbonates reacts with acids to form a salt, water and carbon dioxide.
- Strontium carbonate reacts with sulfuric acid to form strontium sulfate, water and carbon dioxide.
- Therefore, the equation for the reaction is;
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
- The equation is balanced as the number of atoms of each element are equal on both sides of the equation.
Answer:
Add water to the lemon juice to dilute it.
Explanation:
pH value is the measure of alkalinity or acidity of a substance. The pH scale range from 0-14 . The lower the pH value the higher the acidity while the higher the pH value the higher the alkalinity. This simply means on the pH scale , if the pH value is 7 it depicts neutrality. 7 upwards indicates an increasing alkalinity while 7 downwards indicates an increasing acidity.
Acidic substance possess an hydrogen ion (H+) while alkaline substance possess more of hydroxide ions(OH-).
The pH value of lemon juice is usually low at a rate of 2 to 4 pH value . That simply means lemon juice is acidic and contains more hydrogen ions. The best option to increase the pH value of 2 is adding water molecule to neutralize it acidity content.
Adding water molecules(H20) will decrease the acidity and reduce the hydrogen ions that contributes to lemon's juice acidity and invariably increase it pH value.
