Answer:

Electronegativity increases across the period on a periodic table.

Explanation:

Electronegativity is the ability of an atom to attract electron to itself.

All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.

This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.

Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.

This makes them highly reactive and combine readily with other elements.

The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.

Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.

Explanation:

The given elements Na, Al, P and Cl are all elements of period 3.

Atomic number of sodium is 11 with electronic distribution 2, 8, 1.

Atomic number of aluminium is 13 with electronic distribution 2, 8, 3.

Atomic number of phosphorous is 15 with electronic distribution 2, 8, 5.

Atomic number of chlorine is 17 with electronic distribution 2, 8, 7.

An element that has the tendency to readily attract an electron towards itself is known as an electronegative element.

So, out of the given elements chlorine is the most electronegative. Hence, an electron will be most strongly attracted to chlorine.

A sample of sulfurous acid (H2SO3) has a mass of 1.31 g.
lakkis [162]

Answer:

a) 2 (H+) ions

b) 1 (SO3²-) ions

c) 1.36 × 10^-22 grams.

Explanation:

According to this question, sulfurous acid has a chemical formula; H2SO3. It is made up of hydrogen and sulfite ion. Hydrogen ion (H+) is the cation while sulfite ion (SO32-) is the anion.

Based on the chemical formula, there are 2 moles of hydrogen ions that reacts with 1 mole of sulfite ion as follows:

2H+ + SO3²- → H2SO3

Hence;

- there are 2 hydrogen ions (2H+) present in H2SO3.

- there is 1 sulfite ion (SO3²-) present in H2SO3.

c) The mass of one formula unit of H2SO3 is calculated thus:

= 1.008 (2) + 32.065 + 15.999(3)

= 2.016 + 32.065 + 47.997

= 82.08 a.m.u

Since, 1 gram is = 6.02 x 10^23 a.m.u

82.08 a.m.u = 82.08/6.02 × 10^-23

= 13.6 × 10^-23

= 1.36 × 10^-22 grams.

How is a series circuit different from a parallel circuit?
beks73 [17]

Answer:

C. A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through

Explanation:

A circuit that are made of one loop is called series circuit. On the other hand, the parallel circuit has at least two loops. The circuit type has nothing to do with open or closed circuit.

If any part of the series circuit got cut, the current will stop flowing since there is only one loop. A parallel circuit has more loop so the circuit might still work even if a part of the circuit got cut.

What is the molecular formula of each compound?<br> (c) Empirical formula HgCl (m = 5 472.1 g/mol)
beks73 [17]

The molecular formula of HgCl (m = 5 472.1 g/mol) is Hg2Cl4.

The molecular formula is an expression that defines the number of atoms of each element in one molecule of a compound. It shows the actual number of each atom in a molecule.

<h3>Molecular formula: What is it?</h3>

A chemical formula is a way to communicate information in chemistry about the proportions of atoms that make up a specific chemical compound or molecule. Chemical element symbols, numbers, and occasionally other symbols like parentheses, dashes, brackets, commas, and plus and minus signs are used to represent the chemical elements.

A molecule's molecular formula reveals which atoms and how many of each kind are included within it. No subscript is used if there is just one atom of a certain kind. A subscript is added to the symbol for an atom if it contains two or more of a certain type of atom.
