Among the solubility rules previously discussed is the statement: Carbonates, phosphates, borates, and arsenates-except those of the ammonium ion and the alkali metals-are insoluble.
(a) Write the expression for the equilibrium constant for the reaction represented by the equation
CaCO3(s) ? Ca2+(aq) + CO3 -(aq). Is Kc > 1, < 1, or ≈ 1? Explain your answer
0.015 grams Mg was placed in a 153mL flask. The flask was immersed in a water bath whose temp was 24 Celsius. When 5mLs of 1.0M HCL were injected into the flask the attached pressure sensor rose from 100.3 kpa to 108.7 kpa.
A lab procedure requires 35.0 mL of a liquid. Which of the following glassware should be used to obtain the volume with the greatest number of significant figures: 50mL beaker, 100mL erlenmeyer flask, 250mL graduated cylinder, 50mL graduated cylin..
Write an equation of the dissolution reaction for each of the precipitates that was soluble in CH3COOH. Al2(SO4)3+NaOH
For a steel bar deformation begins at 400MPa, it has a modulus of elasticity of 207GPa. a) What is the maximum load that can be applied to a cylindrical specimen 10mm diameter and 60mm long without plastic deformation? b) What is the maximum length ..
How would your results have changed (qualitatively, but explain your reasoning!) id the FAAS standards were all diluted from a stock solution that was reported to be 200ppm but was really only 185
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
if smaller what does this tell you about concentration you determined. write equilibrium exoression to rationalize explanation. How would temp impact ksp
Write a reaction for the formation of a peptide bond between alanine and serine. React the amino group of alanine with carboxyl group of serine. Remember that there are 2 products in this reaction.
