Chose the statements that are TRUE from the list below Group of answer choices Ions exist alone in nature We add calcium carbona

kompoz [17]

Answer:

The first option is false, since limestone has a much more acidic pH than granite. The pH of limestone is between 3.5 and 5.0, while the pH of granite is generally around 4.8 and 5.6.

The second option is false. (Traditionally, lactic acidosis has been classified into two categories: type A and type B. Type A is the result of tissue hypoxia and type B occurs with normal tissue perfusion and a adequate global tissue oxygenation)

The third option is false.

In the fourth option we consider that it is true since the hydrofluoric acid is a weak acid. Hydrogen fluoride actually does dissolve quite freely in water, but the H 3 O + and F - ions are strongly attracted to each other and form the strongly bonded pair, H 3 O + · F -

Explanation:

The third option is considered false since the salts contain an acid and a basic part, where one works as an anion and the other as a cation against dissolution, that is why they are not one or the other, but both chemical characteristics make up the Salt.

There are more or less soluble salts than others, and in turn there are binary, quaternary, tertiary or simple salts.

Y como para contribuir más a la explicación, es importante recordar el grupo de los acidos se clasifica en dons grandes familias, en acidos debiles y fuertes.

Un alcalde ph mas debiles seran, por más tiempo cercano al valor ph: 7 esten menos acidificacion tendran, y cuanto más lejos de la neutralidad este es su numero de ph mas fuertes seran.

What is the mass grams that are in 2.57 × 10²⁵ molecules of I₂

lina2011 [118]

The mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g

From a detailed understanding of Avogadro's hypothesis, we understood 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of I₂ also 6.02×10²³ molecules i.e

<h3>6.02×10²³ molecules = 1 mole of I₂</h3>

Recall:

1 mole of I₂ = 2 × 127 = 254 g

Thus,

<h3>6.02×10²³ molecules = 254 g of I₂</h3>

With the above information, we can obtain the mass of I₂ that contains 2.57×10²⁵ molecules. This is illustrated below:

6.02×10²³ molecules = 254 g of I₂

Therefore,

2.57×10²⁵ molecules = $\frac{2.57*10^{25} * 254}{6.02*10^{23}}\\\\$

<h3>2.57×10²⁵ molecules = 10843.52 g of I₂</h3>

Thus, the mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g
