Answer:
3.5 atm
Explanation:
Given data
- Initial pressure (P₁): 47.9 atm
- Initial volume (V₁): 21 L
We can find the maximum pressure that the gas can exert (final pressure) using Boyle´s law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 47.9 atm × 21 L / 290 L
P₂ = 3.5 atm

Explanation: I asked my chemistry teacher lol
Hey there!
Magnesium chlorate: Mg(ClO₃)₂
Find molar mass.
Mg: 1 x 24.305 = 24.305
Cl: 2 x 35.453 = 70.906
O: 6 x 16 = 96
------------------------------------
191.211 g/mol
We have 187.54 grams.
187.54 ÷ 191.211 = 0.9808
There are 0.9808 moles in 187.54 grams of magnesium chlorate.
Hope this helps!
Answer:
Transition metals, alkali metals, alkaline earth metals Transition metals - Middle of the periodic chart, only average reactivity. alkali metals - As mentioned above, very reactive. Bad choice, going from lower reactivity to higher reactivity.
Hope this answer is right!
The ionization energy or ionization potential is - the energy required to remove an electron from an element in its gaseous state.
