A)Could you add marbles to a beaker filled with sand and get the same results?
B)How does the Particle theory model explain that a substance can be solid while having spaces between its particles?
C)Why does 50 ml of water and 5oml of sugar NOT produce 100 ml of a solution when mixed?
D)How does the particle theory of matter explain the decrease in volume when alcohol is added to water?
THANKS TO ANYONE/EVERYONE WHO HELPS ME OUT!
A. Same results as what?
B. Compare the density of two materials; i.e., Al and Au. Al is about 2.7 g/cc and Au is close to 20 g/cc. So th same mass of Al occupies much more space. Why. Because of the spaces between Au atoms are not th same as spaces between Al atoms.
C. Some of the sugar molecules fit into the spaces between H2o MOLEUCLES.
D. See the answer to C.
how dose the particle theory modle explain that a substance can be solid while having spaces between its particles?
A) No, adding marbles to a beaker filled with sand would not produce the same results. The marbles are generally denser and larger than the sand particles, so they would not fill the spaces between the sand particles. Instead, the marbles would displace the sand, causing it to move and potentially spill out of the beaker.
B) According to the Particle Theory model, substances are made up of tiny, constantly moving particles. Even in a solid state, these particles are not tightly packed together. Instead, there are spaces between the particles. This is because the particles are in constant motion, vibrating in place. The spaces between particles explain why a substance can still be solid while having gaps between its particles.
C) When mixing water and sugar, the volume of the resulting solution may not be exactly 100 ml due to a phenomenon called solvation. The sugar molecules dissolve in the water, occupying some of the space between the water molecules. This leads to a decrease in the overall volume. The exact volume change depends on various factors like the nature of the solute and the solvent, temperature, and pressure.
D) The particle theory of matter can explain the decrease in volume when alcohol is added to water through the phenomenon known as "partial molar volume." When alcohol is added to water, the alcohol molecules insert themselves between the water molecules, disrupting the hydrogen bonding between water molecules. This results in a decrease in the overall volume of the solution. Additionally, alcohol molecules are generally less dense than water molecules, leading to an additional decrease in volume.
A) To answer the question of whether adding marbles to a beaker filled with sand would yield the same results, we need to consider the properties of the substances involved. Marbles and sand are both made up of particles, but they have different sizes and shapes.
If you were to add marbles to a beaker filled with sand, the marbles could potentially displace some of the sand, as they are larger and may not fit into the spaces between the sand particles. However, this would depend on the size of the marbles and the space between the sand particles.
To determine the results, you could conduct an experiment by pouring a known quantity of marbles into the beaker filled with sand and measure any volume changes that occur. You would also need to consider factors such as the size of the particles, the density of the substances, and the particular shape and arrangement of the particles.
