I am a high school chemistry teacher and have been teaching various topics of chemistry for six years.l love to help my students and others in any possible way.
Which of the following compounds can be an alkane?(a) $\mathrm{C}_{2} \mathrm{H}_{4}$(c) $\mathrm{C}_{14} \mathrm{H}_{30}$(b) $\mathrm{C}_{5} \mathrm{H}_{12}$(d) $\mathrm{C}_{7} \mathrm{H}_{8}$
One of the structural isomers with the formula $\mathrm{C}_{9} \mathrm{H}_{20}$ has the name 3 -ethyl- 2 -methylhexane. Draw its structure. Draw and name another structural isomer of $\mathrm{C}_{9} \mathrm{H}_{20}$ in which there is a five-carbon chain.
Give the systematic name for the following alkane:
Draw structures for the following compounds.(a) 3 -ethylpentane(c) $2,4-$ dimethylpentane(b) 2,3 -dimethylpentane(d) 2,2 -dimethylpentane
Four (of six possible) dimethylhexanes are named below. Draw the structures of each, and determine which of these isomers has a chiral carbon center.(a) 2,2 -dimethylhexane(c) $2,4-$ dimethylhexane(b) 2,3 -dimethylhexane(d) 2,5 -dimethylhexane
a) What is the molarity (M = mol/L) of H2SO4 if 25.0 mg is present in 500 mL of aqueoussolution? b) What is the molarity of HCl if 60.0 mg is present in 500 mL of aqueous solution? c) What is the pH of the two solutions? Which has the higher H+ concentration? d) What is the pOH of these two solutions?
Determine the Kc value for the following expression:Na2CO3(s) + 2HCl(aq) ↔ 2NaCl(aq) + CO2(g) + H2O(l)A. Kc = [NaCl]2 [CO2] / [HCl]2B. Kc = [NaCl]2 [CO2] [H2O] / [HCl]2C. Kc = [NaCl]2 [CO2] [H2O] / [Na2CO3] [HCl]2D. Kc = [CO2]
