<u>Answer:</u>

Ion is a charged particle.

A neutral atom contains equal number of positive protons and negative electrons

When an electron is lost or gained the atom becomes a charged particle which is called as an ION.

For example  

Na is an atom which contains 11 electrons and 11 protons (= to atomic number)

When Na loses an electron it will have 11 positive proton and 10 negative electron and Thus, Na will become Na^+, a charge particle which we call it as sodium ion.

Cl is an atom which contains 17 electrons and 17 protons (= to atomic number)

When Cl loses an electron it will have 17 positive proton and 18 negative electron and Thus, Cl will become Cl^-, a charge particle which we call it as chloride ion.

When an ion is positively charged it is called as a cation

When an ion is negatively charged it is called as an anion.

Beryllium forms Be^{+2} cation.we see this in Beryllium chloride BeCl_2.

If BeCl_2 is present in water it forms Beryllium ions which is in Hydrated form that is H_2 O molecules are present  in its ion [Be(H_2 O)_4 ]^{+2}.

Answer:

Explanation:

The symbol of beryllium is Be. It is located in the second group on the periodic table.

Beryllium is a divalent cation with a charge of +2.

It is capable of losing 2 electrons in order to be like the noble gas He and this is a more stable configuration.

What mass of sodium sulfate is needed to make 2.5 L of 2.0 M solution?
Serjik [45]
D) 710 g

Step by Step:
Multiply 2.5 L by 2.0 M to solve for moles
2 mol/L • 2.5 L= 5 mol

Find formula weight of sodium sulfate

Na2SO4-142.04 g/mol

Na- 2(22.99)=45.98
S-32.06
O-4(16)=64

Multiply miles by formula weight

5 mole • 142.04 g/mol=710.2 g

Andreyy89

Answer:

V=162L

Explanation:

Hello,

In this case, we can compute the required volume by using the ideal gas equation as shown below:

PV=nRT

Thus, solving for the volume and considering absolute temperature (in Kelvins), we obtain:

V=\frac{nRT}{P}= \frac{4.70mol*0.082\frac{atm*L}{mol*K}*(21+273)K}{0.700atm} \\\\V=162L

Best regards.

Sever21 [200]

Reaction equations contains symbols which show the physical state of the reactants and products.

<h3>What is a chemical equation:</h3>

A chemical equation is an expression that shows the interaction of reactants to yield products. Usually, symbols such as (s), (l), (g), and (aq) are used to show the state of the reactants and products.

The following are the respective meanings of these symbols;

  • (s) - solid
  • (l) - Liquid
  • (g) - gas
  • (aq) - dissolved in water
