Louis and Keisha each dropped stones from different heights onto pieces of clay to see how much the clay would be compacted. Lou

is dropped his stone onto a small piece of clay and noticed that the clay was smashed a lot. Keisha dropped her stone onto a large piece of clay and noticed that the clay was compacted very little.Should Louis and Keisha conclude that Louis’s stone had more kinetic energy when it hit the clay? Explain why.

This requires familiarity with the different theories (or concepts) of acids and bases.

On the Arrhenius concept, an acid is a substance that produces an H⁺ ion in water such that the H⁺ concentration increases, and a base is a substance that produces an OH⁻ ion in water such that the OH⁻ concentration increases.

On the Brønsted–Lowry concept, an acid is a substance that donates a proton (which is basically an H⁺ ion) in a solvent, and a base is a substance that accepts a proton in a solvent.

On the Lewis concept, an acid is a substance that accepts an electron pair in a solvent, and a base is a substance that donates an electron pair in a solvent.

The concepts become progressively broader, i.e., the Arrhenius concept is the most restrictive and the Lewis concept is the least restrictive. As a corollary, an Arrhenius acid or base is also both a Brønsted–Lowry acid or base and a Lewis acid or base, respectively; a Brønsted–Lowry acid or base is not necessarily an Arrhenius acid or base, but an Arrhenius acid or base is also a Lewis acid or base, respectively. And finally, a Lewis acid or base may not necessarily be either an Arrhenius or a Brønsted–Lowry acid or base.

So, with the above concepts in mind, we can match the statements in column A with the type of acid or base in column B:

\begin{center}\begin{tabular}{ c c } 1 & Bronsted Lowry acid \\  2 & Bronsted Lowry base \\   3 & Arrhenius acid \\ 4 & Arrhenius base \\ 5 & Lewis base \\ 6 & Lewis acid\end{tabular}\end{center}

What is the ratio of hydrogen atoms (h) to oxygen atoms (o) in 2 l of water? enter the simplest whole number ratio in order of h
KiRa [710]

Answer:- 2,1

Explanations:- Water is H_2O and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.

Hence, the answer is 2,1.

The saturation point for a solution is 45.0 grams of solute per 500 grams of solvent. If you pour 50.0 grams of
zheka24 [161]

Answer:

5.00 g  of solute  will remain undissolved at the bottom of the container

Explanation:

From the question, the solubility of the solute in the given solvent is 45.0 grams of solute per 500 grams of solvent.

Now if i pour 50.0 grams of  solute into 800 grams of solvent, it means that only 45 g will dissolve in 500 g of solvent leaving the additional 5 g undissolved.

Hence, 5 g  of solute  will remain undissolved at the bottom of the container.

A sample has a hydrogen ion concentration of 1 ⋅ 10^−2. What happens if the hydrogen ion concentration increases?
makkiz [27]
If the concentration of the hydrogen ions, increase then the solution would become more and more acidic and thus have a lower pH value than compared to the pH value before at the 1.0 X 10^-2 M.
