Answer:
52.99 kPa
Explanation:
Initial volume V1 = 2.7 L
Initial Pressure P1 = 78.5 kPa
Final Volume V2 = 4.0L
Final Pressure P2 = ?
Temperature is constant
The relationship between these quantities is given by the mathematical expression of Boyles law. This is given as;
V1P1 = V2P2
P2 = V1P1 / V2
P2 = 2.7 * 78.5 / 4.0
P2 = 52.99 kPa
Answer:
Explanation:
The symbol for TIN is Sn.
When Sn loses 2 electrons, it gets a double positive charge ( +2 ) and becomes 
.
It becomes a cation.
The name of Ion is Tin ( II ) Ion.

Answer:
The correct answers are: <u>Each oxygen of carbonate ion has -2/3 or -0.67 charge.</u>
<u>Bond order of each carbon‑oxygen bond in the carbonate ion</u> = <u>1.33</u>
Explanation:
The carbonate ion (CO₃²⁻) is an organic compound, in which a carbon atom is covalently bonded to three oxygen atoms. The net formal charge on a carbonate ion is −2.
The carbonate ion is <u>resonance stabilized</u> and has three equivalent resonating structures, which exhibits that all the three carbon-oxygen bonds in a carbonate ion are equivalent.
In the resonance hybrid of carbonate ion,<u> the negative charge is equally delocalized on all the three oxygen atoms. </u>
<u>Thus, each bonded oxygen has -2/3 or -0.67 charge.</u>
<u />
In a carbonate ion there is one double bond oxygen (C=O) and two single bonded oxygen (C-O). Bond order of 1 C=O is 2 and bond order of C-O is 1.
∴ <u>Bond order</u> = sum of all bond orders ÷ number of bonding groups = (2+1+1) ÷ 3 = <u>1.33</u>
