Answer:
6.75 sym.
Explanation:
Boyle's Law: The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.
Empirically => P ∝ 1/V => P = k(1/V) => k = P·V
For any conditions of Pressure & Volume, Pressure x Volume is a constant.
Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ = P₁V₁ / V₂
=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.
Is it multiple choice if so can you put them down
If:
work done = force x distance
distance = work done ÷ force
so:
50 ÷ 2.5 = 20m
3. The Chemical property of an unknown element is the number of valence electrons
4. The number of protons in one atom of an element
Hope I helped :))
Answer:
I think the total number of valence electrons in a water is 8.
