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.

Calculate the masses.
malfutka [58]

Answer:

a) Mass = 3.9 g

b) Mass = 0.395 g

Explanation:

Density is related to the mass and volume of a substance by the relation:

Density = \frac{Mass}{Volume}----(1)

a) Given:

Volume  = 4.00cm3

Density = 0.97 g/cm3

Based on equation (1)

Mass = density*volume = 0.97 g/cm3*4.00 cm3 =3.9 g

b) Given:

Volume  = 125 ml

Density = 3.16 g/L

1 ml = 0.001 L

Therefore, 125 ml = 0.125 L

Based on equation (1)

Mass = density*volume = 3.16 g/L*0.125L =0.395 g
