Why did the antacid disslove faster when broken up into smaller pieces?
Breaking the antacid into smaller pieces increases the surface area exposed to the solvent, allowing for more efficient dissolution. This results in faster dissolution because the solvent can more easily reach and react with the molecules of the antacid.
Why hot metals easily be beaten into shape?
Hot metals can be easily beaten into shape because heating them makes the metal more malleable and ductile. This reduces the amount of force required to deform the metal, allowing it to be shaped and molded more easily. Heating also causes the metal to lose its crystalline structure, making it less brittle and prone to cracking during the shaping process.
Which group of carbohydrates cannot be hydrolyzed to give smaller molecules?
Polysaccharides (such as starch and cellulose) are the group of carbohydrates that cannot be hydrolyzed to give smaller molecules. They consist of long chains of monosaccharides linked together by glycosidic bonds that are not easily broken down by hydrolysis.
Why can short range dislocation obstacles be overcomed by heating?
Heating increases the mobility of atoms within the material, allowing dislocations to move more easily around obstacles. This results in the dislocations being able to overcome the short range obstacles that were hindering their movement.
Why is phosphine a gas?
Phosphine is a gas at room temperature because its molecules are relatively small and have weak intermolecular forces. This results in low binding energy between the molecules, allowing them to move freely and escape into the gas phase easily.
Why do solvent molecules evaporate easily?
Solvent molecules evaporate easily because they have low intermolecular forces holding them together, allowing them to escape into the gas phase more readily. Additionally, solvent molecules often have weaker interactions with the solute molecules, allowing them to break free and evaporate more easily.

Does gas compress easily?
Yes, gas compresses easily because the molecules in a gas are far apart and have high kinetic energy, allowing them to move closer together when pressure is applied. This is why gas can be compressed into a smaller volume compared to liquids and solids.
Do larger molecules diffuse more readily than smaller molecules?
No, smaller molecules generally diffuse more readily than larger molecules because they can move through pores and gaps in substances more easily due to their smaller size. This is why smaller molecules like oxygen and carbon dioxide can diffuse through cell membranes more quickly than larger molecules like proteins.

Molecules A and B are both organic molecules found in many cells when tested it is found that molecule A cannot pass through a cell membrane but molecule B easily passes through state one way the two?
Molecule A may be too large or too polar to pass through the cell membrane effectively, while molecule B may be smaller and more nonpolar allowing it to pass through easily via diffusion. The difference in membrane permeability between the two molecules could be due to variations in size, charge, polarity, or interaction with membrane proteins.

When a solvent is heated it can dissolve more what and less what?
When a solvent is heated, it can dissolve more solute (increased solubility) because the increased temperature increases the kinetic energy of solvent molecules, allowing them to break apart solute molecules more easily. On the other hand, heating the solvent can decrease the solubility of gases since gases are less soluble in warmer solutions due to decreased gas solubility at higher temperatures.
Why can you compress a gas but not liquid or a solid?
The question is based on the misconception that liquids and solids cannot be compressed: they can. The molecules of gas are further apart allowing them to be compressed more easily.
Why you can easily move your hand in air but not in solids?
When moving your hand in the air, the molecules are more spread out, allowing you to easily push through the spaces. In solids, the molecules are closely packed, creating resistance when trying to move your hand through them. This resistance is what makes it harder to move your hand in solids than in the air.
