Answer:
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Explanation:
Let's consider the unbalanced single displacement reaction between chlorine and potassium bromide.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + KCl(aq)
We will start balancing Cl atoms by multiplying KCl by 2.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Finally, to get the balanced equation, we have to multiply KBr by 2.
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
The periodic table is a representative of all elements we know today.
Answer: Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
I making my page look smart :)
1. 0+15+30+45+60=150/5=30 s
0+10+16+22+27=75/5=15 cm^3
then, 15/30= 0.5 cm^3/s(average rate of rxn)
2. 0+15+30+45+60+75+90+105+120=540/9=60 s
0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3
then, 24.89/60=0.414cm^3/s (avrg rate of rxn)
3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn
4. 16/30= 0.533cm^3/s
5. 39.5/105= 0.37cm^3/s
