devlian [24]

This is covalent network type of solid.

For example, silicon dioxide (SiO₂) is covalent network solid with covalent bonding.

Covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.

Silicon(IV) oxide has continuous three-dimensional network of SiO₂ units and diamond has sp3 hybridization.

This solids do not have free electrons so they are good insulators.

They have strong covalent bonds, so they melt at extremely high temperature.

Other examples are quartz, diamond, and silicon carbide.

What is the definition of an Arrhenius acid?
Lorico [155]

Answer:

I <u>think</u> your answer is: C. ("An Arrhenius acid increases [H +] in the solution.")

Explanation:

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H + ); that is, an acid increases the concentration of H + ions in an aqueous solution. This causes the protonation of water, or the creation of the hydronium (H 3 O +) ion.

Hopefully this helps!

Have a great day! ^^

Which statement is true about the atomic mass?
nikdorinn [45]

the correct answer is A.

Each atom has three sub particles, which are electron, proton and neutron. To get the atomic mass for each atom, one has to add the masses of the proton, neutron and electron in an atom. For each atom, the major contributors to its mass are proton and neutron, this is because the mass of the electron is very small indeed. Thus, the atomic mass of an element is usually in the range of its mass number, which is obtained by the summation of proton and neutron. Since it is the number of proton that indicate an atomic number and it is the mass number that indicate atomic mass, therefore, atomic mass can be greater than the atomic number.
