<h3>
Answer:</h3>
1270 Psi
<h3>
Explanation:</h3>
<u>We are given;</u>
- Pressure in the tank, P₁ as 422 psi
- Temperature in the tank, T₁ as 20.0 K
- New temperature in the tank, T₂ as 60.0 K
We are required to determine the pressure at 60.0 K
- We are going to use the pressure law;
- According to the pressure law, the pressure of a gas is directly proportional to the temperature at constant volume.
- That is;
- Thus,
- At different pressures and temperature;
- Thus, rearranging the formula;
Hence;
Therefore;
P₂=1266 Psi
= 1270 Psi
Thus, the pressure at 60.0 K is 1270 Psi
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
The volume of gas that exerts a pressure of 457 mmhg if exerted a pressure of 2.50 atm when its volume was 25.0ml is calculated as follows
by use of Bolyes law formula that is P1V1=P2V2
P1= 457mmhg
V1=?
P1 = 2.50 atm = 2.50 x760 = 1900mmhg
V2= 25,0 ml
V1 from the formula above = P2V2/P1
= 1900mm hg x25 ml/ 457 mm hg = 104 ml
Answer:
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.
