Metalloids are all solid at room temperature<span>. Some metalloids, such as silicon and germanium, can act as </span>electrical<span> conductors under the right conditions, thus they are called semiconductors. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is brittle - a characteristic of some nonmetals).

What is the particle theory
kolezko [41]

Answer:

The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.

Six main points of the particle theory:

• All matter is made of particles.

• Particles have space between them.

• Particles are always moving.

• Particles move faster and get farther apart when heated.

• Particles are attracted to each other.

• All Particles of the same substance are identical

To determine the molar mass of an unknown organic acid, HA, a 1.056 g sample is titrated with standardized NaOH. Calculate the m
meriva

Explanation:

Equation for the given reaction is as follows.

     HA(aq) + NaOH(aq) \rightarrow NaA(aq) + H_{2}O(l)

Therefore, moles of NaOH and HA are calculated as follows.

     Moles of NaOH = 0.256 M \times 0.03378 L

                                = 8.64 \times 10^{-3}

                                = 0.00864 mol

     Moles of HA = 0.00864

Also,  moles = \frac{\text{weight}}{\text{molecular weight}}

      Molecular weight = \frac{1.056 g}{0.00864 mol}

                                    = 122.22 g/mol

Thus, we can conclude that molar mass of given unknown organic acid is 122.22 g/mol.

What happens when an atom forms an ion?
Snowcat [4.5K]

Answer:

An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge.
