When compounds that are formed by ionic bonds decompose the products are usually what?
When compounds formed by ionic bonds decompose, the products are typically the separate ions that made up the original compounds. This decomposition process usually occurs when the ionic compound is subjected to heat, electricity, or chemical reactions that break the bonds holding the ions together.
What is formed in the air when hydrogen burns besides water?
Water is the only substance formed but energy (primarily in the form of heat) is also given off.
How was serpentine formed?
Serpentine is a metamorphic mineral, so it was formed by high heat and great pressure, most often from peridotite.
How serpentine formed?

Is a candle burns chemical reaction?
Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.Yes, whenever a candle burns, it is a combustion reaction between the carbon compounds of the wick and wax of the candle and of oxygen in the air. These compounds burn to create carbon dioxide and water, and also a few smaller carbon compounds, which is evident as the smoke rising occasionally from the flame. The flame you see and the heat you feel rising off of the burning wick is the evidence of an exothermic chemical reaction.Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.
How is carbon dioxide formed in quick bread?
Carbon dioxide is the result of the reaction between the yeast compounds and the gluten. The heat process causes the compounds to expel the carbon dioxide, which expands more than the oxygen in the bread.
How does a flat iron produce heat?
Through metals which are good conductors of heat: often these are compounds of metals which can ( due to the tight particles producing energy) heat to a desired temperature, copper being an example of this.
What is the general name given to the compounds formed when elements burn in oxygen?
Oh honey, we're talking about oxides here. When elements get cozy with oxygen and start burning, they form these compounds called oxides. It's like a fiery love affair between elements and oxygen, leaving behind these sassy oxides as their legacy.
5 indacations that a chamical reaction or change has accured?
- color change - precipitate - irreversible - heat given off - bubbles formed
What do you call the heat given to or given up from a substance?
The heat given to or given up from a substance is called heat transfer.
Why is coal a compound?
Coal is not a compound, but rather a complex mixture of organic compounds and inorganic minerals. It is formed from the remains of plants that have been subjected to heat and pressure over millions of years. The main organic compounds in coal are carbon, hydrogen, and oxygen.
What are the 3 examples of chemical change?
A solid is formed in a liquid (precipitate) The change isn't easy to reverse. Heat or light is given off.
