Answer: There are about 0.28 molecules in 43.9 g of carbon tetrachloride. If you are rounding up, it would be 0.3
Explanation:
Cm^3 = mL
1.11 g/cm^3 = 1.11 g/mL
Density (g/mL) multiplied by volume (mL) will give us the mass (g)
1.11 g/mL * 385 mL = 427.35 g
And since we have 3 significant figures, we have 427. g.
Answer:
This is google's answer for the last question
Explanation:
The kinetic energy increases as the particles move faster. The potential energy increases as the particles move farther apart. How are thermal energy and temperature related? When the temperature of an object increases, the average kinetic energy of its particles increases.
Answer: The spontaneous intermingling of atoms among different substances is accomplished by diffusion.
Explanation:
Diffusion means to spread out. In diffusion, the molecules or atoms move from a region of high concentration to low concentration.
In other words, we can say that the spontaneous intermingling of atoms among different substances is accomplished by diffusion. Diffusion depends on the random walk of an atom or molecule.
Molecular kinetic energy is the energy of a gas at ordinary temperature in which the atoms or molecules are in rapid motion.
Displacement is the property in which a reactive element displaces less reactive element from its position.
Condensation is the process of changing water vapor into liquid.
Thus, it can be concluded that the spontaneous intermingling of atoms among different substances is accomplished by diffusion.
