A scientist conducts an experiment to determine the rate of NO formation in the reaction N2(g) + O2(g)–>2 NO(g).If the initial concentration of N2 was 0.500 M and the concentration of N2 was 0.450 M after 0.100 sec, what is the rate of the reaction? Show work

You have been given an assertion statement and a reason. Select from A- D to locate the correct statement ? A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true. Assertion (A): AgBr will precipitate before AgCl when a solution containing 0.050 M AgNO₃, 0.030 M NaCl, and 0.030 M NaBr is mixed. Reason (R): Ag⁺ ions have a stronger attraction to Br⁻ than to Cl⁻ because bromide is a larger anion.

Calcium oxalate, CaC2O4, is a common component of kidney stones and dissolves according to: CaC2O4(s)        Ca2+(aq)+C2O42−(aq) Given that the solubility product constant Ksp=2.3×10−9 Explain how high concentrations of calcium or oxalate ions in urine can lead to kidney stone formation. If the concentration of C2O42- in urine is 1.0×10−4 , calculate the maximum Ca2+ concentration before precipitation occurs. Show calculations on the scratch paper.
