The statement is False.
Ethanol is one of many toxic substances found in tobacco smoke.
Ethanol is used in the manufacture of drugs, plastics, lacquers, polishes, plasticizers, and cosmetics. Ethanol is utilized in remedy as a topical antiinfective, and as an antidote for ethylene glycol or methanol overdose.
Ethanol is a natural chemical compound. it's far simple alcohol with the chemical formula C₂H₆O. Its system can be additionally written as CH ₃−CH ₂−OH or C ₂H ₅OH and is frequently abbreviated as EtOH. Ethanol is a risky, flammable, colorless liquid with a characteristic wine-like smell and pungent taste.
Within the worst instances, there can also be respiratory problems, low blood strain, incontinence coronary heart troubles, blood troubles, liver damage, and loss of life.

Given:
0.103 grams of Zinc (solid)
50 ml of HCl
Density of HCl = 1.0 g/mL
Initial Temperature (Ti) = 22.5 C
Final Temperature (Tf) = 23.7 C
Solve for the mass of HCl:
50 mL * 1.0 g/mL = 50 g
Assume that the Cp for HCl is similar to the Cp of water:
q = mCpdT
= mCp (Tf - Ti)
= 50 g * 4.18 J/gC * (23.7 - 22.5)
q = 250.8 J = H
Answer:
A.)
Explanation:
The first structure accurately represents ethyl ethanoate because there is an ethyl group (2 carbons) directly attached to the oxygen within the parent chain and there are 2 carbons (the eth- in ethanoate) attached to the double bonded oxygen.
The second structure is not ethyl ethanoate. There is an ethyl group directly attached to the oxygen within the parent chain. However, there are 3 carbons attached to the double bonded oxygen. This makes the structure ethyl propanoate.
