On the pH scale, a 7 indicates _____. a base an acid neutrality

Chemistry
1 answer:
worty [1.4K]3 years ago
3 0

The correct answer is:

neutrality

on the pH scale 7 is neutral above 7 is basic and below 7 is acidic.

Explanation:

The pH is an example of how acidic/basic water is. The scale goes from 0 - 14, with 7 being neutral, pH of less than 7 designates acidity, whereas a pH of greater than 7 intimates a base. pH is really a pattern of the relative amount of free hydrogen and hydroxyl ions in the water.pH is a measure of how acidic/basic water is.

It is neutral because, at this pH, the molar concentrations of Hydroxide and Hydronium are same, therefore the substance is not a base nor an acid.

If 23.5 g of magnesium occupies 13.5 cm^3 what is the density of magnesium
lara31 [8.8K]

The density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³

<h3>What is Density ?</h3>

Density is the measurement of how tightly a material is packed together.

It is defined as the mass per unit volume.

Given ;

  • Mass = 23.5 g
  • Volume = 13.5 cm³

Formula to calculate density ;

Density = mass / volume

             =23.5 / 13.5 = 1.74 g/cm³

Hence, the density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³.

How do I do question number 3? And what is the answer?
shutvik [7]

Answer:

60.02 g.

Explanation:

  • It is clear from the balanced equation:

<em>Mg + 2HCl → MgCl₂ + H₂. </em>

that 1.0  mole of Mg reacts with 2.0 moles of HCl to produce 1.0 mole of MgCl₂ and 1.0 moles of H₂.

  • 20.0 g of Mg reacts with excess HCl. To calculate the no. of grams of HCl that reacted, we should calculate the no. of moles of Mg:

<em>no. of moles of Mg = mass/atomic mass</em> = (20.0 g)/(24.3 g/mol) = 0.823 mol.

  • From the balanced equation; every 1.0 mol of Mg reacts with 2 moles of HCl.

∴ 0.833 mol of Mg will react with (2 x 0.833 mol = 1.646 mol) of HCl.

<em>∴ The mass of reacted HCl = no. of moles x molar mass</em> = (1.646 mol)(36.46 g/mol) = <em>60.02 g.</em>
