independent variable is temperature and dependent is the number of cold drinks sold. It's because the temperature is being changed without any outer influence while the number of cold drinks sold changes based on the weather. It's like cold drinks are going to sell better in the summer because it's hot vs in the winter because it's cold. The change in temperature isn't relying on anything but the drink is.

4. Consider the following statement made in Chapter 4 of the text: "... consider that if the
AveGali [126]

The claim: "If the nucleus were the size of a grape, the electrons would be one mile away on average" is reasonably accurate because the ratios between the nucleus's sizes and the distances (between electrons and nucleus) for the two given examples are in the same order of magnitude.      

To know if the claim is accurate we need to calculate the ratio of the size of the nucleus (the same as a grape) and the distance between the electrons and the nucleus for example 1 (r₁):  

r_{1} = \frac{s_{1}}{d_{1}}    (1)

and to compare it with the ratio of the size and the distance given in example 2 (r₂):

r_{2} = \frac{s_{2}}{d_{2}}    (2)

<em>Where:</em>

s₁: is the size of the nucleus (like the size of a grape)

d₁: is the distance between electrons and nucleus of example 1 = 1 mile

s₂: is the average diameter of the nucleus  = 10⁻¹³ cm

d₂: is the average distance between electrons and nucleus of example 2 = 10⁻⁸ cm

Assuming that the diameter of a grape is 3 cm (in a spherical way), the ratio of the <u>first example</u> is (eq 1):

r_{1} = \frac{3 cm}{1 mi*\frac{160934 cm}{1 mi}} = 1.86 \cdot 10^{-5}

Now, the ratio of the <u>second example</u> is (eq 2):

r_{2} = \frac{10^{-13} cm}{10^{-8} cm} = 1.00 \cdot 10^{-5}              

Since r₁ and r₂ are in the same order of magnitude (10⁻⁵), we can conclude that the given claim is reasonably accurate.

In the reaction of an acid with water, a hydronium ion forms
Nutka1998 [239]
Really, ionization takes place. It means the acid dissociates in water. Ionization is just a fancy way of saying dissociation. Always think easy. 

Definition of IONIZATION: The process describing the dissociation of an acid in water.

If it ionizes or dissociates completely in water, then it shows that hydronium is a STRONG ACID. And if it ionizes partially, that shows hydronium is a WEAK ACID.

So, the answer will be choice B. by a process called ionization
