How is stomach growling an example of a chemical reaction?
A gas is evolved as a product of a chemical reaction.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
What are energy changers?
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
How would you capture hydrogen from a chemical reaction of an acid and a metal?
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.
What heat gas production and color change can all be evidence of chemical change.?
- A gas is evolved from reactants only if a chemical reaction occured.- The same situation for the color change.These are very possible signs but they are not absolute; many other factors must be studied.
The starting substances that are evoled in a chemical reaction?
The substances evolved after a chemical reaction are called in English products and are not starting substances - the are called reactants.
How you call the starting substances that are evolved in a chemical reaction?
Reactants.
How is stomach growling an example of a chemical reaction?
A gas is evolved as a product of a chemical reaction.
If you are trying to decide whether a chemical reaction does or does not take place when two substances are mixed what kind of evidence will you look for?
change of state change of colour fizzing/gas bubbles
What is the meaning of chemical energy?
It's the potential of a chemical substance to sustain a transformation by a chemical reaction or, to transform other chemical substances. Batteries are an example. Making or breaking of chemical bonds involves energy, which may be absorbed or in other situation it may be evolved from a chemical system.
What is the starting material in a chemical reaction?
Check your local newspaper, online ads, and local signage for places to lease. As for what is the best kind of space for a small business, that would depend on what type of small business you're planning on opening.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
What is dust smoke or chemical?
- Dust is a fine powdered solid in the atmosphere (a suspension)- Smoke is a mixture of materials (solid, liquid, gases) evolved during burning.- Chemical fume is composed from substances (solid, liquid, gases) evolved during chemical reactions.
Is when a match burns heat is evolved an observation law or theory?
Burning (combustion) is a chemical reaction - oxidation; this reaction is exothermic. This is a law.
What is dust smoke or chemical fumes?
- Dust is a fine powdered solid in the atmosphere (a suspension)- Smoke is a mixture of materials (solid, liquid, gases) evolved during burning.- Chemical fume is composed from substances (solid, liquid, gases) evolved during chemical reactions.
What happens to energy and matter in a chemical reaction?
Energy and matter are both conserved during a chemical reaction, but the energy may change form, for example, from chemical potential energy to evolved heat. The matter also forms a new type of chemical bond and/or breaks an old type of chemical bond.
What are energy changers?
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
