<h2>
Reacting Substances</h2>
To determine what would occur when two substances react, we must identify their charges.
There is what's called the criss-cross method where we put the substances with their charges side by side, and criss-cross their charges to get the number of atoms there are for each substance.
<h2>Solving the Question</h2>
We're given:
Mg has a charge of +2 and Cl has a charge of -1:
⇒
Criss-cross the charges:
⇒
Therefore, for every 1 atom of magnesium, there would be 2 atoms of chlorine.
<h2>Answer</h2>
For every 1 atom of magnesium, there would be 2 atoms of chlorine.
Answer:
The answer to your question is below
Explanation:
Data
Volume 1 = V1 = 3000 l
Temperature 1 = T1 = 30°C
Pressure 1 = P1 = 99 kPa
Volume 2 = ?
Temperature 2 = T2 = 16°C
Pressure 2 = P2 = 45.5 kPa
Process
1.- To find the new volume we need to convert the temperature to °K
T1 = 30 + 273 = 303°K
T2 = 16 + 273 = 289°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve it for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (99 x 3000 x 289) / (303 x 45.5)
-Result
V2 = 85833000 / 13786.5
V2 = 6225.8 l
There are no conversion factor ratios.
