A.has mass and takes up space
1.
The balanced chemical reaction is:
N2 +3 I2 = 2NI3
We are given the amount of product formed.
This will be the starting point of our calculations.
3.58 g NI3 ( 1 mol NI3 / 394.71 g NI3 ) ( 3
mol I2 / 2 mol NI3 ) = 0.014 mol I2.
Thus, 0.014 mol of I2 is needed to form the
given amount of NI3.
Explanation:
A 57.9 g sample of glass is cooled by 2.70'C how much heat does it release
1560
Element:- Gold.
Compound:- Sodium Chloride (NaCl).

Isotopes:- two atoms of hydrogen, each with a different number of neutrons
Cation:- an atom that has developed a positive charge.
Anion: an atom that has gained a negative charge
Answer: It is important to conduct multiple trials so one can get the best results, additionally, multiple trials with result in minimal errors. Finally it is important to conduct multiple trials because it will show you the actual answer/solution/whatever. If you do something once their may of been a random unknown affect and you would of never knew because you only conducted the experiement once.
