It is c: a conductor that operates only at low temperatures
The chemical reaction would be written as:
2Na + Cl2 = 2NaCl
Since we are given the amounts of the reactants available for reaction, we have to determine the limiting reactant. And use this amount to calculate for the theoretical yield.
55 g Na ( 1 mol / 22.99 g ) = 2.39 mol Na
67.2 f Cl2 ( 1 mol / 70.9 g ) = 0.95 mol Cl2
Therefore, the limiting reactant would be Cl2 since it is the one consumed completely.
0.95 Cl2 ( 1 mol NaCl / 1 mol Cl2) = 0.95 NaCl produced from the reaction
Answer:
The name of the molecule which is given below is 2-pentene.
Explanation:
Alkenes are the organic compounds which are composed of carbon and hydrogen atoms, in which double bond is present.
In the given diagram:
Each corner and joints shows the carbon atoms and number of carbon atoms in it is 5.
One double bond is present in the 2nd position.
So the compound is 2 pentene.
Hence, 2 pentene is the name of the compound.
Answer:
The mismatched pair is : D. phenolics-peracetic acid
Explanation:
A. sodium hypochlorite-chlorine: Correct pair
Sodium hypochlorite solution (NaOCl) is made from the reaction of chlorine and sodium hydroxide solution.
B. formalin-formaldehyde : Correct pair
The formalin solution is a 37% aqueous solution of formaldehyde.
C. iodophor-iodine : Correct pair
Iodophor, a combination of iodine and solubilizing agent. When diluted with water, iodophor releases free iodine.
D. phenolics-peracetic acid : wrong pair
Phenolics is a noun used for phenols, aromatic hydrocarbons with a hydroxyl group. Whereas, peracetic acid or peroxyacetic acid is an organic peroxide.
E. benzalkonium chloride-quaternary ammonium compound: Correct pair
Benzalkonium chloride is a quaternary ammonium organic salt, used as a cationic surfactant.
