Mg ribbon is allowed to react with hcl and another with ch3cooh in which fizzing will occur more vigorously and why?
Mg ribbon will react more vigorously with HCl compared to CH3COOH because HCl is a stronger acid than CH3COOH. This higher acidity of HCl results in a faster reaction rate with magnesium, leading to more intense fizzing.
Why two different substances have different melting point?
Different substances have different melting points because the strength of intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces) vary between substances. Substances that have stronger intermolecular forces require more energy to overcome them, resulting in a higher melting point. Conversely, substances with weaker intermolecular forces have lower melting points as they require less energy to transition from solid to liquid state.
Why can different substances be different phases at room temperature?
This is because different substances have varying inter molecular forces due to electron distributions. Also the weakest of the attractive forces are found in the gases and the stronger ones are found in the solids.
Why does Magnesium React with hydrochloric acid more vigorously than acetic acid?
Magnesium reacts more vigorously with hydrochloric acid because HCl is a stronger acid than acetic acid, so it can more easily donate protons to react with the magnesium. This reaction generates hydrogen gas and forms magnesium chloride. Acetic acid is a weaker acid, so it reacts more slowly and less vigorously with magnesium.

Does the melting point depend on the substances being melted?
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.

Why does smoking attack your health?
Because the smoke of a cigarette contains about 4,000 dangerous substances. What do you think that FOUR THOUSANDS of dangerous substances can do to your organism? To make you stronger and healthier?
In a chemical change how is the new substance different from the original substances?
Because it changes the identity of the old substances

What 'e'describes what most substances do when they get hot?
When most substances get hot, they tend to expand. This phenomenon occurs because the increased thermal energy causes the particles within the substance to move more vigorously, leading to greater distances between them. As a result, the overall volume of the substance increases. This behavior is a fundamental characteristic of solids, liquids, and gases, although the degree of expansion can vary among different materials.

Why do the pigments separate during column chromatography?
Because the retention coefficients of different substances are also different.
