What else can I help you with?
What is true about combustion reactions?
Combustion reactions involve a substance combining rapidly with oxygen gas to produce heat, light, and often a flame. They are exothermic reactions, meaning they release energy in the form of heat. Combustion reactions are commonly used in engines, stoves, and heaters.
What always the basis of behavior?
response to stimuli
Do shield volcanoes produce quiet or explosive eruptions?
Eruptions at shield volcanoes are almost always non-explosive.
Do all neutralization process neutral salts is produce?
Neutralization reactions (combination of a base and an acid) will always produce a salt and water, with salt meaning any ionic compound that isn't an oxide.
The mortality rate in otoplasty is most closely associated with what complication?
The mortality rate in otoplasty is extremely low and is almost always associated with anesthesia reactions.
Can tissues be inflamed but not infected?
Yes, tissues can be inflamed without being infected. Inflammation is a natural immune response to various stimuli, such as injury, allergens, or autoimmune reactions, and does not always involve pathogens like bacteria or viruses. Conditions such as arthritis or allergic reactions can cause inflammation without any underlying infection.
What type of reactions always release energy?
exothermic reactions
Why are formations of odor and color not always signs of a chemical reaction?
because a part of reactions either don't produce any gasses and/or solids or they are produced, but are odour- and/or colorless
Why are combustion reactions considered exceptions to the rules of chemical reactions?
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
Do purple flowers always produce purple flowers?
Almost always, but genetic studies show that differential features can slightly change it. Also, if they cross pollenate by bee, animal, human, or wind.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Are single displacement and double displacement reactions always redox reactions?
No, single displacement and double displacement reactions are not always redox reactions. Redox reactions involve electron transfer between reactants, while single displacement and double displacement reactions do not always involve the transfer of electrons.
