the difference is where the triple bond occurs. if it occurs between the first and second carbon it is 1-butyne if the triple bond occurs between the second and third carbon it is 2-butyne the difference is where the triple bond occurs. if it occurs between the first and second carbon it is 1-butyne if the triple bond occurs between the second and third carbon it is 2-butyne
It is a chemical change, some other signs of chemical changes you should look for to differentiate between physical and chemical changes are: thermal energy radiating off of the objects, the result in another object that has different properties then the first two, etc...
Acids release hydrogen ions (H+) in water, while bases release hydroxide ions (OH-) in water. You can differentiate between an acid and a base in a chemical reaction by measuring the pH of the solution. Acids have a pH less than 7, while bases have a pH greater than 7.
Chemical change. References: Intro to Matter book.
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
Coefficients should be placed in front of the chemical formulas in a chemical equation to balance it. They are used to ensure that the number of atoms of each element is the same on both the reactant and product sides of the equation.
True
As your child...you should not differentiate at all.
Differentiate between solicited and un-solicited letters
Assign a different number to each... no?

you should know better Jehovah and Christ in order to differentiate them.
chemical, pathogen, enzyme, hormone
No, it should not. It is not difficult to differentiate between tennis and table tennis.
Yes, magazine titles should be italicized when used in an essay. This is to differentiate them from the rest of the paragraph.
