irinina [24]

Answer:

Use a magnet; Mixture

Explanation:

Suppose you have a container filled with iron and sand. You can separate the iron from the sand if you use a magnet so this is a mixture.

  • A mixture is made up of two more components that are not chemically combined.
  • Mixtures may be classified as homogeneous when the components are in the same phase or heterogeneous when the components are in different phases.
  • A mixture of sand and iron is an example of solid-solid mixture which can be separated using a magnet.
  • The magnet will attract the iron in the mixture leaving the sand.

If an atom of the following element had a neutral charge, how many electrons would it have?
Yakvenalex [24]

Answer:

31

Explanation:

In order for an atom to have a neutral charge, it needs to have the same number of protons and electrons. You can see by the illustration that the atomic number is 31, so this element has 31 protons. Knowing that, we also know that it must have 31 electrons to be neutral.

A base has a molarity of 1.5M w.R.T the hydroxyl ion concentration. If 7.35 cm3 of this base is taken and diluted to 147 cm3, th
daser333 [38]

Answer:

0.077M is the concentration of the hydroxyl ion

Explanation:

Dilution factor is the ratio between the aliquot that is taken of a solution and the total volume of the diluted solution.

For the problem, dilution factor is:

7.53cm³ / 147cm³ =<em> 0.05122</em>

To obtain molarity of a diluted solution you must multiply dilution factor and initial molarity of the solution, thus:

1.5 M × 0.05122 = <em>0.077M is the concentration of the hydroxyl ion</em>

How many acidic H+ ion is given by H3BO3 in aqueous solution?? ...?
notka56 [123]
Boric acid, H3BO3, in aqueous solution would only give out one H+ ion. As it is also produce OH ion and by hydrolysis it produces one proton. <span>All the boron compounds (BX3) are having only 6 valence electrons in it and should follow the octet rule by taking another electron.</span>
