Answer:
Solution given:
e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide
Solution given:
<u>Balanced</u><u> </u><u>chemical</u><u> </u><u>equation</u><u>:</u>
<u>when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide</u>
<u>f</u>) chromium (III) hydroxide plus sulfuric acid
<u>Balanced chemical equation:</u>
<u>When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.</u>
g) aluminum metal plus chlorine gas
<u>When aluminum metal is added to chlorine gas</u><u> </u><u>Combination reaction takes place and forms aluminum chloride.</u>
Hello There! ^_^
Your question: What is the pressure of a fixed volume of hydrogen gas at 38.8°C if it has a pressure of 1.36 atm at 15.0°C..?
Your answer: P1/ T1= P2/ T2
Change C to Kelvin
273+ C= K
38.3+ 273= 311K
15.0+ 273= 288K
2.38/ 288= P2/ 311.3
740.894= 288 (P2)
P2= 2.57 atm.
Thus, you got you answer!
Hope this helps!

Answer:
Three
Explanation:
1. Draw a Lewis structure
- Put the least electronegative atom (C) in the centre
- Attach the O and two S atoms to the C.
- Add enough electrons to give each atom an octet.
2. Draw the resonance structures
You should get one of the structures below.
It has a double bond and two single bonds.
The resonance structures will have the double bond in each of the other two positions.
