At Blueprint, we believe in educating first. Our MCAT blog was created to reflect this value. Our articles are written by the same MCAT experts who write our MCAT books, MCAT practice exams, and our MCAT course materials. We also partner with guest contributors regularly, both professionals and industry experts, to make sure that you are getting information that is not only relevant, but accurate.
Learn from the best with this free MCAT resource, updated with new articles regularly. If you need to know about a specific MCAT subject, changes being made to the MCAT exam, and general information about the MCAT, our blog is the perfect place for you.
Consider the following reaction: C6H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) ΔH = – 2808 kJ / mol Under what conditions will this reaction proceed spontaneously? A. Low temperature, low pressure B. Low…
The webinar session was run by Clara Gillan, one of our lead instructors and content developers. Clara discussed strategies that will help students conquer this difficult section of the exam. Unlike the science sections of the MCAT, there is no…
Which of the following processes occur at the same temperature? I. Boiling II. Condensation III. Sublimation IV. Evaporation A) I and IV only B) I and II only C) II and III only D) I, II, and IV only
The Keq for the following hypothetical reaction is 5.16 x 10-6. A2B (g) + C2 (g) → ABC (s) + AC (g) Which of the following is true concerning this reaction? A) The Keq value indicates that reactants are highly…
Hydrogen bonds form between H2O molecules, but not H2S, H2Se, or H2Te. This explains why: a) H2O is liquid at room temperature while the other compounds are gases. b) H2O is more volatile than the other compounds. c) H2O has…
The distance from a point charge is tripled. What is the ratio of the strength of the electric field at the original distance to the strength of the field at the new distance? a) 9:1 b) 3:1 c) 1:3 d)…
A researcher constructs a hypothetical reaction that follows a mechanism that uses the two reactions below: 3 Q2 + 2 AX4 → 2AX3Q + 2XQ + 2Q– 1. AX3+ Q2→ AX3Q + Q– 2. 2 AX4 + Q2 → AX3Q…
