Why do molecules combined into chains?
PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K
(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)
n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
Answer: Alcohol
Explanation:
A neutralization reaction involves the combining of an acid and a base to create a salt and water. Reactants = acid + base. Products = salt + water. No alcohol is involved with a neutralization reaction.

Explanation:
Answer:
The correct answer is 6.31 M
Explanation:
The molecular weight (MM) of NaOH is calculated as follows:
MM(NaOH) = Molar mass Na + Molar mass O + Molar mass H
= 23 g/mol + 16 g/mol + 1 g/mol
= 40 g/mol
We need the MM to convert from grams to moles. The molarity (moles of solute per liter of solution, in mol/L) can be calculated by dividing the mass into the volume in liters (195 ml = 0.195 L) and then multiplying by the MM as follows:
M = 49.24 g/0.195 L x 1 mol/40 g = 6.31 mol/L = 6.31 M
