Based on Heisenberg's uncertainty principle, the position and velocity of a particle cannot be determined simultaneously with accuracy.
In other words, Heisenberg's uncertainty principle states that the more accurately we know the position of a particle the less accurately we can know its velocity. Mathematically it is given as:
Δx.mΔv >= h/2π
where: Δx = uncertainty in position
m = mass
Δv = uncertainty in velocity
h = plancks constant
Answer:
V₂ = 21.3 dm³
Explanation:
Given data:
Initial volume of gas = 3.00 dm³
Initial pressure = 101 Kpa
Final pressure = 14.2 Kpa
Final volume = ?
Solution;
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
101 Kpa × 3.00 dm³ = 14.2 Kpa × V₂
V₂ = 303 Kpa. dm³/ 14.2 Kpa
V₂ = 21.3 dm³

Answer:
The electron cloud keeps the surronds the atom like abubble and the orbit is what the electrons go around
Explanation:
Answer:
It depends what the compound is.
Explanation:
You need to use Avogadro's number (6.22*10^23) to convert the number of molecules of a compound to moles of the compound. From there, you can use the molar mass of the compound (grams per mole) to get the mass. You can get the molar mass by googling "molar mass of [compound]" or calculate it yourself using the periodic table.
So: 8.2*10^11 molecules of the compound * (1 mole of the compound/6.022*10^23 molecules of the compound) * (# of grams/1 mole of the compound)
Yuppppp they are absolutely rightt
