What else can I help you with?
What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
A substance that undergoes a change in a chemical reaction?
A reactant
What is the rate of disappearance formula used to calculate the speed at which a substance is consumed or transformed in a chemical reaction?
The rate of disappearance formula is used to calculate the speed at which a substance is consumed or transformed in a chemical reaction. It is typically expressed as the change in concentration of the reactant over time.
What is the scientific definition of reactant?
Something that reacts to another substance.
Is burning alcohol in oxygen a physical or chemical change?
Burning alcohol in oxygen is a chemical change because it involves a chemical reaction that produces new substances with different properties. The alcohol (ethanol) reacts with oxygen to form carbon dioxide and water vapor, which are completely different from the original alcohol molecules.
What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
How does your mood change after you have consumed alcohol?
There is no standard set of mood changes that every person will experience when they have consumed alcohol. Some people actually become more "lively", outlandish, and wild, while other may be come more gloomy, distraught, surly, and further still people may not even have a change at all. The latter largely depends on the amount of alcohol consumed.
A substance that undergoes a change in a chemical reaction?
A reactant
What is the nameof the reactant consumed by the reaction?
The name of the reactant consumed in a reaction depends on the specific chemical reaction being referred to. In general, reactants are the starting substances that undergo a chemical change. If you provide more details about the specific reaction, I can give you the exact name of the reactant involved.
Why is burning alcohol a chemical change?
Burning alcohol is a chemical change because it involves a chemical reaction where the alcohol molecule is broken down into different substances (such as carbon dioxide and water) with new properties. Energy is released during the reaction, and the composition of the alcohol is permanently altered.
What is the rate of disappearance formula used to calculate the speed at which a substance is consumed or transformed in a chemical reaction?
The rate of disappearance formula is used to calculate the speed at which a substance is consumed or transformed in a chemical reaction. It is typically expressed as the change in concentration of the reactant over time.
When Liquid ethyl alcohol turns into a solid when placed in a low-temperature freezer a chemical reaction?
It does but it is Not a chemical change its physical change...
What is the scientific definition of reactant?
Something that reacts to another substance.
Do catalysts change during a reaction?
No
Is burning alcohol in oxygen a physical or chemical change?
Burning alcohol in oxygen is a chemical change because it involves a chemical reaction that produces new substances with different properties. The alcohol (ethanol) reacts with oxygen to form carbon dioxide and water vapor, which are completely different from the original alcohol molecules.
If ethyl alcohol boils at 79 degrees Celsius a physical or chemical change?
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
What happens when delta h is positive?
When ΔH (the change in enthalpy) is positive, it means that the reaction is endothermic, absorbing heat from its surroundings. This indicates that energy is being consumed rather than released during the chemical reaction.
