Why can't some substances not go through chemical changes easily?
Some substances have stable chemical structures, making it difficult for them to undergo chemical changes. This can be due to strong bonds holding the atoms together or a lack of reactive sites for other substances to interact with. Additionally, factors such as temperature, pressure, and presence of catalysts can also influence the ease of chemical changes in a substance.
Why are petrol pumps made out of aluminium?
Petrol pumps are made out of aluminum because it is lightweight, durable, and resistant to corrosion from fuels and other chemicals. It also allows for ease of manufacturing and maintenance due to its malleability and strength.
What physical characteristics are important in the construction of laboratory devices used for measuring accurate volumes of liquids?
Important physical characteristics for laboratory devices used for measuring accurate volumes of liquids include precision in calibration markings, uniformity in construction material to prevent chemical interactions, and a tight seal to prevent evaporation or leakage. Additionally, ergonomic design for ease of handling and usage is crucial for accurate measurements.
What is chemical names replaced with?
Chemical names are often replaced with chemical formulas or common names for simplicity and ease of communication. For instance, "sodium chloride" is commonly referred to as "table salt," while its chemical formula is NaCl. In professional settings, using IUPAC nomenclature provides a standardized way to name compounds, ensuring clarity across different languages and regions.
When sand and gravel mix together is it reversible?
Yes, the mixing of sand and gravel is a physical change, which means it is generally reversible. You can separate sand and gravel by using methods like sieving or washing, as their different sizes and densities allow for such separation. However, the ease of separation may depend on the specific mixture and the method used.
Is flmmability a chemical or physical property?
Chemical property; flammability implies ease of burning, and burning is a chemical change.
Is conductivity of a metal a chemical?
Conductivity is not a chemical, it is the faculty of different metals to allow electrons to travel inside a conductor with more or less ease. This is a physical property.
Is the flammability of ether a physical or chemical change?
The flammability of ether is a chemical change because it involves the breaking and forming of chemical bonds to produce heat and light. When ether reacts with oxygen during combustion, new chemical compounds are formed.
Is reactivity a physical or chemical property of matter?
Reactivity is a chemical property of matter that describes how easily a substance undergoes chemical reactions with other substances. It is related to the ease with which the atoms of an element combine with other atoms to form compounds.
What are the benefits of using an aluminum frame for a window screen?
Using an aluminum frame for a window screen offers benefits such as durability, resistance to corrosion, lightweight construction, and ease of maintenance.
Does physical therapy work for headaches?
Physical therapy treatment can treat headaches without any painkillers. Our therapists will teach you how to manage and ease headaches.
What metal is a fork made out of?
Forks are commonly made of stainless steel, which is a metal alloy composed of iron, chromium, and nickel. This material is chosen for its durability, corrosion resistance, and ease of cleaning.
What does the ease of changing production to respond to price change determine?

What is the series?
An activity series is a list of elements organized according to the ease in which an element can undergo certain chemical reactions.
What are the benefits of using black PEX pipe for plumbing installations?
The benefits of using black PEX pipe for plumbing installations include its flexibility, resistance to corrosion and chemicals, durability, and ease of installation.
