Answer:
Explanation:
The decomposition of follows the equation
By definition, the rate of a chemical reaction can be expressed by
The rate of appearance of is related to the rate of disappearance of by the stoichiometry. This means that, for each mole of that appears 2 moles of are consumed. So
Answer:
if you want the symbol of atom the answer is Boron
Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
Answer:
evaporation means the state of the water went from liquid to gas which is a physical change. the sugar is still in the beaker which means its chemical properties did not change.
