In the following reaction, how many grams of lead (ii) nitrate pb(no3)2 will produce 425 grams of sodium nitrate (nano3)?

List four observations that indicate that a chemical reaction may be taking place

Summarize possible ways in which phases of matter could combine to form a solution.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
