AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!
1 mole contains = 6.02x10^23 atoms. 0.31mole contains = 0.31x6.02x10^23 = 1.8662x10^23.
Answer:
9L
Explanation:
Given parameters:
Initial volume V₁ = 3.6L
Initial pressure P₁ = 2.5atm
Final pressure P₂ = 1atm
Unknown:
Final volume V₂ = ?
Condition: constant temperature = 25°C
Solution:
This problem compares the volume and pressure of a gas at constant temperature.
This is highly synonymous to the postulate of Boyle's law. It states that "the volume of a fixed mass of gas is inversely proportional to the pressure provided that temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
where P and V are pressure and volume
1 and 2 are initial and final states
Input the parameters and solve for V₂;
2.5 x 3.6 = 1 x V₂
V₂ = 9L
