Does an ice cream melting in a bowl count as a chemical reaction?
No, its a physical change. It make be changing from a solid to a liquid, but it is not changing at a chemical level, only at a physical level. No matter how you slice it, it is still ice cream (but maybe a little drippy).
How does vinegar act as a neutralizer in chemical reactions?
Vinegar acts as a neutralizer in chemical reactions by reacting with bases to form water and a salt, which helps to balance the pH level and neutralize the solution.
Is reacting to air a physical or chemical property?
Reacting to air is a chemical property because it involves a change in the chemical composition of the substance when it comes into contact with oxygen in the air, leading to the formation of new compounds. It reflects how a substance interacts with its environment on a molecular level.
What is the difference between phyical and chemical changes?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
How is a chemical combination different from a physical combination of elements?
A chemical combination involves elements or compounds reacting and forming new substances with different properties due to rearrangement of atoms at a molecular level. A physical combination is a mixture where elements or compounds retain their original properties and can be physically separated through methods like filtration or distillation.
Is the addition of heat to solid sodium chloride until it melts a chemical reaction?
Chemical reactions happen on a molecular level Physical reactions are concerned with a change in state or energy level, so melting is considered a physical reaction since there is no molecular change just a change in state.
Why ice melting a chemical change?
Ice melting is a physical change rather than a chemical change because the substance (water) remains the same at a molecular level. The process involves a change in state from solid to liquid due to the absorption of heat energy, with no alteration to the chemical composition of the material.
What electrons of an element are responsible for reacting and bonding with other elements?
Valence electrons are responsible for reacting and bonding with other elements. These are the electrons in the outermost energy level of an atom and determine the atom's ability to form chemical bonds with other atoms.
What energy level of an atom affects the chemical behavior of different elements?
The highest level. Or the outer, valence shell.
Can matter undergo changes in both its physical and its chemical properties Explain please?
Yes, matter can undergo changes in both its physical and chemical properties. Physical changes involve alterations in the form or state of matter without changing its chemical composition, such as melting ice into water. Chemical changes, on the other hand, involve transformations at the molecular level, resulting in the formation of new substances with different chemical properties, such as rusting of iron.
Is the addition of heat to solid sodium chloride until it melts is a chemical reaction?
Chemical reactions happen on a molecular level Physical reactions are concerned with a change in state or energy level, so melting is considered a physical reaction since there is no molecular change just a change in state.
What is the melting point of water at sea level and what happens to this point at altitudes above sea level?
i think you mean what is the melting point of ice as water cant melt. the melting point of ice at sea level is 100 degres celsius
