Answer: False
Explanation:
An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.
A base is defined as the substance which looses hydroxide ions when dissolved in water.
If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.
If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.
The 3rd diagram is a mixture because it has 2 substances
Answer:
8 moles
Explanation:
When we are asked to convert from grams of a substance into moles, we have to use the substance's molar mass.
Meaning that for this problem, we'll <em>use the molar mass of hydrogen peroxide</em> (H₂O₂), as follows:
There are 8 moles in 272 grams of hydrogen peroxide.
Answer: Larger molecules have stronger London forces.
Explanation:
Pentane therefore has a stronger force than butane.
