What else can I help you with?
What evidence do we have that changing sand to glass is a chemical change?
Glass contain not only melted sand but also other compounds forming new compounds.
What happens to the properties of atoms when they combine to form compounds?
they change!!
How do chlorine compounds change the chemical properties of a pool?
chemical
Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
What ways can the properties of glass be change?
It can be heated and change appearance, can be painted or stained, can be hardened.
Is breaking glass is a physical or chemical change?
Purely physical.
If properties of elements change they are mixed together and the mixture if called what?
If the properties of elements change when they are mixed together, the mixture is called a compound. Compounds result from chemical reactions between elements, where the atoms are bonded together in specific ratios. These compounds often possess unique properties distinct from their individual element components.
Do the properties of elements change when combined to form compounds true or false?
no they dont chane
How do the properties of the parts of a mixture compared to the properties of the parts before they become A mixture?
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
Do the properties of glass changed by heating?
Yes, heating glass can change its properties. When heated, glass may become softer, more malleable, and easier to shape due to increased molecular mobility. However, overheating can cause the glass to lose its shape, crack, or even melt, depending on the temperature achieved.
Which of the properties of glass would convince you that it isn't an ionic compound?
The lack of high melting and boiling points characteristic of ionic compounds would suggest that glass is not an ionic compound. Additionally, the absence of a regular repeating crystalline structure seen in ionic compounds further supports this conclusion. Glass is an amorphous solid, indicating a different bonding structure compared to typical ionic compounds.
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
