Answer:
323.15 °C
Explanation:
Considering the ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of the gas.
P ∝ T
Also,
Using Charle's law
Given ,
P₂ = 2P₁
T₁ = 25 °C
T₂ = ?
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using above equation as:
New temperature = 596.3 K
Also,
T(K) - 273.15 = T( °C)
<u>So, Temperature = 596.3 - 273.15 °C = 323.15 °C</u>
Answer:
Explanation:
A stable compound has a net charge of 0. Basically, when added, the two ion charges must equal 0 and balance each other out.
We have one ion with a charge of +4. There is another ion of -2. Clearly, these are not balanced yet.
We need more -2 ions to balance it. If we have 2 ions, then their charge is -4 because:
- 2 * -2 charge = -4 charge
The +4 ion and 2 -2 ions (with a charge of -4) balance each other out and create a net charge of 0. So, <u>2 ions with a charge of -2</u> are necessary to create a stable compound.
