We will balance the equation in the following order: metals, amethals, carbon, hydrogen and oxygen (the most common order).
The metal present in the equation is Sr, which is already balanced (there are 1 on each side of the equation).
The amethal present in the equation is Cl. There is 2 Cl in the left side and only one in the right side. So, we will multiply the quantity of the molecule that contains Cl by 2. Doing this, we'll obtain:
Looking at the equation, we can see that it is now fully balanced. Hence, a balanced equation of the reaction is:
Answer:
<u>A Quantative Observation</u>: A type of observation which can be counted or measured, often using tools like a thermometer, a scale, or a ruler.
<u>Observation:</u> All the data collected during scientific investigations. It is best gathered by doing the investigation yourself, not reading other peoples’ work.
<u>Scientific Law</u>: a specific relationship under given conditions that tells what happens in the natural world. Based on a body of evidence, they are universal and will rarely if ever change.
<u>Scientific Theory</u>: a well-supported and widely accepted explanation of nature. They can and do change if new evidence arises.
I hope I got these right and I hope you got the help you wanted!
Answer:
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
Explanation:
The rate expression of the zero order kinetic are :
![R=k[A]^o](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5Eo)
[A]= initial concentration of reactant
k = rate constant
R = rate of reaction
We have :
Rate constant of the reaction , k = 0.0020 mol/L s

R = 0.0020 mol/L s
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
