Properties of the following are:
Alpha particle - positively charged particle (+) that consists of two electrons and two neutrons.
Cathode rays - it is the stream of electrons (negatively charged) found in vacuum.
Protons - are particles that carry positive charge and is present inside the nucleus of an atom.
Electrons - are particles that carry negative charge and is present in the orbits of the atom.
Neutrons - electrically neutral particle (0 charge) present inside the nucleus of an atom. However, it has its own mass.
the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.
<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>
As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.

Answer:
0.20M
Explanation:
Molarity (by definition) = moles / Volume in Liters
∴Molarity = 0.030mol/0.15Liter = 0.20M
Yes it is possible
Explanation:
Galena and gold can become encrusted together. They can form together in the same geologic setting.
- Gold usually occurs freely in nature uncombined with other atoms.
- Galena is the largest ore of lead.
- Both minerals can become twinned under appropriate geologic conditions.
- They are usually seen in pegmatitic intrusions in a rock body as product of late stage melt crystallization.

Answer:
NaCl
Explanation:
Thus, for the compound between Na + and Cl −, we have the ionic formula NaCl (Figure 3.5 "NaCl = Table Salt").
