Which of the following would have the smallest atomic radius? K+ Se2- Ca2+

Let's remember the Bronsted-Lowry theory to answer this specific question. According to the theory, acid is a proton donor, while a base is a proton acceptor.

Consider an acid in a form HA (aq) and base in a form of B (aq). Since acid is a proton donor, it will donate its hydrogen ion to the base, B. The resultant products would be $A^{-}$ (aq) and $BH^{+}$ (aq).

Remember that an acid-base reaction is an equilibrium reaction. This means we may also look at this proton transfer reaction from the product side towards the reactants. Summarizing what has been said, we may write the equilibrium as:

$HA (aq) + B (aq)$ ⇄ $BH^{+} (aq) + A^{-} (aq)$

Now acid, HA, donates a proton to become a conjugate base. The conjugate base, if we look from the reverse equation side, is actually a base, since it can accept a proton to become HA. Similarly, B accepts a proton to become a conjugate acid. Looking from the reverse reaction, it can now donate a proton, so in reality we can consider it a base.

To summarize, your logic is correct.

Answer:

The freshwater sources that are generally in continuous motion and follow a defined path are called streams and rivers.

If I were to improve the lab then I will make the following changes:

The experiment aimed to observe and model the effects of rivers on erosion. So, I can make a virtual model of the river and can compare the velocity, gradients and volume of rivers.

Comparison between the low and high factors listed can help in computing the effect of the powerful river on erosion.

The high velocity. gradient and volume of the river will cause more erosion as it exerts more force.

The low volume, gradient and velocity river will affect in a less manner on erosion.

Explanation:

thats all i know ( correct me if im wrong please)
