KCl : K+ as cation and Cl- as anion
Answer:
3.55atm
Explanation:
We will apply Boyle's law formula in solving this problem.
P1V1 = P2V2
And with values given in the question
P1=initial pressure of gas = 1.75atm
V1=initial volume of gas =7.5L
P2=final pressure of gas inside new piston in atm
V2=final volume of gas = 3.7L
We need to find the final pressure
From the equation, P1V1 = P2V2,
We make P2 subject
P2 = (P1V1) / V2
P2 = (1.75×7.5)/3.7
P2=3.55atm
Therefore, the new pressure inside the piston is 3.55atm
Answer:
- Shredded leaves
- Small bits of straw or hay, finely shredded
- Shredded paper
- Torn cardboard in small bits
Tip: The smaller the pieces, the faster it decomposes. Even fruits and veggies can decompose quickly if they are blended or chopped into small portions. If you add some worms to the compost pile, everything should decompose quickly! Just remember to avoid eggshells because they take FOREVER to decompose.
