Hello!</h2>
The answer is:
The new temperature will be equal to 4 K.
<h2>
Why?</h2>
We are given the volume, the first temperature and the new volume after the gas is compressed. To calculate the new temperature after the gas was compressed, we need to use Charles's Law.
Charles's Law establishes a relationship between the volume and the temperature at a gas while its pressure is constant.
Now, to calculate the new temperature we need to assume that the pressure is kept constant, otherwise, the problem would not have a solution.
From Charle's Law, we have:
So, we are given the following information:
Then, isolating the new temperature and substituting the given information, we have:
Hence, the new temperature will be equal to 4 K.
Have a nice day!
Answer:
26.3 mol O₂
Explanation:
Step 1: Write the balanced equation
4 FeCl₃ + 3 O₂ ⇒ 2 Fe₂O₃ + 6 Cl₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of FeCl₃ to O₂ is 4:3.
Step 3: Calculate how many moles of O₂ are needed to react completely with 35.0 mol of FeCl₃
We will use the previously established molar ratio.
35.0 mol FeCl₃ × 3 mol O₂/4 mol FeCl₃ = 26.3 mol O₂
If it's a cube you use this formula Edge to the 3rd power example if the edge of a cube is 6 you supposed to do 6 times 6 times 6 which is 216
Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
