What does a positive triangle h for a molecule mean?

Answer 1

I'm not sure exactly what triangle you are talking about, but if it is in an equation, it means "change in" whatever variable it is next to (and the proper word for it is "delta").

In the specific case where it's written under or over the arrow in a reaction, it means "heat" as in "you have to heat this in order to make the reaction happen."

A point-down triangle is pronounced "del" and is somewhat different mathematically, but it's still related to the concept of change. A triangle can also be an instrument in chemistry that holds a crucible in labs.

ok well i think what your asking, is what the triangle above the arrow in an equation means. I'm pretty sure it means heat. So if there is a triangle above the arrow in a reaction equation it means that heat was used to make this reaction occurs. hope that helps

Answer 2

A positive triangle symbol (Δ+) above a molecule indicates that the molecule is electrophilic, meaning it can accept electrons in a chemical reaction. This symbol is often used in organic chemistry to represent an electron-deficient species that can react with nucleophiles.

Answer 3

Fire triangle has three things called Oxygen , fuel and heat [ these are the things you need to create a fire !
