3. Benzene contains only carbon and hydrogen and is 7.74% hydrogen by mass; the molar mass of benzene is
78.1 g/mol. Determine the empirical formula of benzene. (4 pts)
4. Balance the following equation and use it for the problem that follows:
Pb(NO3)2(aq) + _KI(aq) → _KNO3(aq) + _Pb126)
25.0 mL of 0.400 mol/L Pb(NO3)2(aq, is mixed with 300.0 mL of 0.220 mol/L KI. What is the maximum
(aq)
amount of precipitate (the solid on the product side) that can form (ie the theoretical yield)? (7 pts)

I need help with these questions in chemistry lab
I need help with these questions in chemistry lab1) Assume an air bubble had been in the buret tip when you took your first reading and it was replaced by NaOH during the course of the titration. Would your experimental value for the concentration of NaOH be too high, too low, or unchanged as compared to the true value? Explain 2) Assume the buret had been wet with water because it was not adequately rinsed with base. Would your experimental value for concentration of NaOH be too high, too low, or unchanged as compared to the true value? Explain3) Using your calculated concentration of NaOH from lab how many grams of KHP would you need to start with in order to have an end point at 35.00 mL?4) If 0.839 g of KHP were titrated, and 34.58 mL NaOH solution were necessary to reach the equivalence point, what is the concentration of the NaOH solution? (Make sure to report the correct number of significant figures).*** Make sure it's not plagiarized

Metamorphic Rocks Laboratory
Write a short paragraph describing each of the two rocks (thus two paragraphs). Photograph each rock with a sense of scale (a pen, a coin, a ruler). The photographs must be in focus. Use the "macro" setting on your camera; usually it's indicated by a little "tulip" icon like this: Post your pictures in the Rock Identification Working Area discussion board (one thread per assigned group of three students).With your assigned group (again; see Announcements), collectively identify your rocks and verify each other's identifications. You can seek validation of your identifications from the instructor.Once the identifications are solid, collaborate to answer the following five questions for each rock sample in the group:What type of rock is this? (igneous, metamorphic, or sedimentary)What are the dominant minerals in the rock? (e.g., quartz, biotite, calcite, etcWhat is the name of the rock? (e.g., basalt, granite, sandstone, etc.)Where is this rock from? (Where did you obtain the rock?)What processes were responsible for creating this rock? (Interpret the history behind this rock sample.)If igneous, describe the character of the melt that generated the rock (mafic or felsic) and its cooling history (aphanitic vs. phaneritic: extrusive or intrusive?).
