I think that the sun is the center of the universe, not a human being. Everything revolves around the sun, not someone. U know when to sleep, when the time is, and when to wake up based on the sun. All the planets revolve around it. This is why I think the sun is the center of the universe, not a human being.
If the equation is complete the products would be manganese chloride and oxygen gas would be given off.
MnCl2 + O2
Answer:
Explanation:
None of the statement is true for both chemical and nuclear reactions. In chemical reactions, mass is always conserved and the type of atoms are also conserved.
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
