Answer:
The volume of the balloon will be 5.11L
Explanation:
An excersise to solve with the Ideal Gases Law
First of all, let's convert the pressure in mmHg to atm
1 atm = 760 mmHg
760 mmHg ___ 1 atm
755.4 mmHg ____ (755.4 / 760) = 0.993 atm
922.3 mmHg ____ ( 922.3 / 760) = 1.214 atm
T° in K = 273 + °C
28.5 °C +273 = 301.5K
26.35°C + 273= 299.35K
P . V = n . R .T
First situation: 0.993atm . 6.25L = n . 0.082 . 301.5K
(0.993atm . 6.25L) / 0.082 . 301.5 = n
0.251 moles = n
Second situation:
1.214 atm . V = 0.251 moles . 0.082 . 301.5K
V = (0.251 moles . 0.082 . 301.5K) / 1.214 atm
V = 5.11L
Answer:
Magnesium + iron chloride → iron + magnesium chloride
Explanation:
It is the single replacement reaction.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Molecular equation:
Magnesium + iron chloride → iron + magnesium chloride
Chemical equation:
Mg(s) + FeCl₂(aq) → MgCl₂(aq) + Fe(s)
Ionic equation:
Mg(s) + Fe²⁺(aq) + 2Cl⁻(aq) → Mg²⁺(aq) + 2Cl⁻(aq) + Fe(s)
Net ionic equation:
Mg(s) + Fe²⁺(aq) → Fe(s) + Mg²⁺(aq)
Answer:
c
Explanation:
because forces act on an object and make it change direction based upon strength hope this helps.
