Answer:
C₂H₂(g) + 2.5 O₂(g) ⇒ 2 CO₂(g) + H₂O(l) ΔH° = -1300 kJ/mol
Explanation:
In the combustion of acetylene, it reacts with oxygen to produce carbon dioxide and water. The corresponding chemical equation is:
C₂H₂(g) + 2.5 O₂(g) ⇒ 2 CO₂(g) + H₂O(l)
The thermochemical equation includes the balanced chemical equation, stating the states of aggregation and the enthalpy of the reaction.
C₂H₂(g) + 2.5 O₂(g) ⇒ 2 CO₂(g) + H₂O(l) ΔH° = -1300 kJ/mol
Denitrification is part of the nitrogen cycle
If you have a hamster with short fur, what possible genotypes could the hamster have?
Answer: <u>FF or Ff </u>
Explanation:
If you have a hamster with short fur, what possible genotypes could the hamster have? FF or Ff . ... The mystery hamster was a genotype ff and the phenotype for long fur and the parents can create offspring that have long fur or short fur because they are heterozygous dominant.

1) 2K(s) + 2H₂O(l)→ 2KOH(aq) + H₂<span>(g)
This is a single replacement reaction where K reacts with H</span>₂O , displaces the H⁺ ion in water and combines with OH⁻ to form a base.

2) 2B</span>i(NO₃)₃(aq) + 3H₂S(g)→ Bi₂S₃(s) + 6HNO₃<span>(aq)
</span>This is a double displacement reaction where the ions are exchanged and form new compounds. Since ions are exchanged between 2 compounds its called double displacement.
3) 2HNO₃<span>(aq) + Ba(OH)</span>₂<span> → Ba(NO</span>₃<span>)</span>₂<span>(aq) + 2H</span>₂O<span>(l)
This is an acid base reaction where nitric acid and barium hydroxide react to form the respective salt and water</span>
The chemical formula of chromium (II) nitrate is as shown below.
Cr₂NO₃
The number in the subscript of the chemical formula of the given element signifies the number of atom or ions of the given element. In this regard, based on the chemical formula written for chromium (II) nitrate, the number of chromium ions would have to be 2.
