Answer:
Option B. Single replacement reaction
Explanation:
To know which option is correct, it is important that we know the definition of each option. The definition of each option is given below:
1. Synthesis reaction is a reaction in which two different elements or compound combine together to produce a new compound different from the two starting elements or compound. An example is illustrated below:
C + D —> E
2. Single replacement reaction is a reaction in which an element replaces or displaces another element in a compound. An example is illustrated below:
D + BC —> B + CD
3. Combustion reaction is a reaction in a substance react with oxygen to generate carbon dioxide (CO₂) and water (H₂O). An example can be seen when organic compound react with oxygen to produce carbon dioxide (CO₂) and water (H₂O). This is illustrated below:
CₓHᵧ + (x + y/4) O₂ —> xCO₂ + (y/2) H₂O
4. Double replacement reaction is a reaction in which the ions of the two reacting compound replaces one another to form new products. This is illustrated below:
X⁺Y¯ + U⁺V¯ —> X⁺V¯ + U⁺Y¯
5. Decomposition reaction is a reaction in which a large compound breaks down into two or more elements or compound. An example is illustrated below:
GH —> G + H
Now, observing the equation given in the question above:
Sn + 2HCl —> SnCl₂ + H₂
We can see that Sn replaces H in HCl to produce SnCl₂.
Therefore, the reaction is a single replacement reaction.
Answer:Correct
Explanation:According to the balanced chemical reaction, 2 mol FeBr3 are consumed for every 3 mol Na2S consumed.
Phosphoenol pyruvate enzyme is not part of gluconeogenesis.
<h3>Phosphoenol pyruvate</h3>
The ester formed when pyruvate and phosphate are combined to form an enol results in phosphoenol pyruvate (2-phosphoenolpyruvate, or PEP). As an anion, it exists. In biochemistry, PEP is a crucial intermediary. Involved in glycolysis and gluconeogenesis, it boasts the highest-energy phosphate bond yet discovered in an organism (61.9 kJ/mol). It also plays a role in carbon fixation and the manufacture of a number of aromatic chemicals in plants. In bacteria, it provides energy for the phosphotransferase system. Enolase reacts with 2-phosphoglyceric acid to produce PEP as a result. Pyruvate kinase (PK) converts PEP to pyruvic acid, and this process produces adenosine triphosphate (ATP) via substrate-level phosphorylation. One of the main units of currency for chemical energy in cells is ATP.

Answer:
+4
Explanation:
The oxidation number of C in carbon dioxide (CO2) is (rules 1 & 2): 0 + (2 x 2) = +4 [Check (rule 3): +4 + 2(-2) = 0] The oxidation number of C in methane (CH4) is (rules 1 & 2): 0 – (4 x1) = -4 [Check (rule 3): -4 + 4(-1) = 0].
Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. ... Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1.
