<h2>
Hello!</h2>
The answer is: The new pressure of the gas is 3.6 atm.
<h2>
Why?</h2>
From the statement we know that the gas is kept at a constant temperature of 0°C, so, if the gas keeps a constant temperature we can use the Boyle's Law to solve this problem.
The Boyle's Law states that:
Where,
P is the pressure of the gas.
V is the volume of the gas.
So, the given information is:
Now, substituting it into the Boyle's Law equation to calculate the new pressure, we have:
So, the new pressure is 3.6 atm.
Have a nice day!
V1/T1=V2/T2
(10)/(358K)=(V2)/(278)
V2=7.765363128 L
Answer:
The combining capacity or power of iron in FeCl3 is +3
Explanation:
The combining capacity or power of an atom of an element is the charge which that atom possesses when it combines with other atoms to form compounds. It is also known as valency or valence.
To determine the combining capacity of iron in FeCl3, the following steps are followed:
1. Group 7 elements have a combining capacity of -1, therefore, the combining capacity of Chlorine in FeCl3 is -1
2. The sum of oxidation numbers of a neutral compound is zero, therefore, Fe + 3 × Cl = 0
Let, the combining capacity of Iron be y.
y + (-1 × 3) = 0
y - 3 = 0
y = +3
Therefore, the combining capacity of iron in FeCl3 is +3
The collection of elements on the right side of the periodic table with electron sequetianlly filling the p orbitals of their valence shells are named noble gases.
The noble gases are in the group 18.
The last orbital of the noble gases are:
Gas last orbital
He 1s
Ne 2p6
Ar 3p6
Kr 4p6
Xe 5p6
Rn 6p6
As you see the p orbitals of the noble gases are complete. That is what confere them their great stability.
Answer:
The Solar Nebula Theory accounts for the creation of solar systems, stars, and planets. The theory accounts for planet composition by stating that iron compounds, silicates, and dust clump together to form planetesimals. Because of the proximity of the sun, ices and gases cannot condensate near them, so they do not become gas giants. The planetesimals then collide together due to gravity and collect to form our rocky planets.
