Are the labs in Exploring Creation with Chemistry really college prep?
Chemistry Experiment 15.2 , Step 21, says the solution should be bluer, but the explanation on p. 546 says pink. Can you explain this?
Chemistry Sample Lab Report
Does it matter that my Lewis structures do not look exactly like the ones in the answer book?
Do non-bonding electrons need to be drawn as pairs in a Lewis structure?
Do you have additional help for the calorimetry problems?
Do you have any general help for significant figures?
Do you have a sample calculation for Experiment 9.2?
For Example 3.2, how do I do the math?
For Example 3.3, how do I do the math?
For Module 1, Test Question 17, why is the answer rounded to the tens place?
For Module 5, Review Question 8, how can two atoms have the same electronegativity? Doesn't electronegativity vary when moving in different directions on the periodic chart?
For On Your Own 5.10d, why can't I put the F’s across from each other and the Cl’s across from each other? Wouldn’t the bonds cancel each other out, then, and make the molecule non-polar covalent?
How can I find denatured ethanol for the alcohol burner?
How did Hess discover that the enthalpy of formation for elements in their elemental form is zero?
How did you arrive at the answer for Module 4, Test Question 14?
How did you get K2SO4 as a product for Module 9, Practice Problem 10?
How do I balance the equation in On Your Own 9.4c?
How do I convert from grams of sodium stearate to moles of sodium stearate in Experiment 7.1?
How do I determine the salt produced in acid/base reactions in Module 9?
How do I distinguish between ionic, polar covalent, and nonpolar covalent?
How do I figure out the significant figures in Module 12, Practice Problem 7?
How do I find powdered drain cleaner or lye for Experiments 2.1, 9.1, 10.3, and 13.1?
How do you know that the salt in On Your Own 13.1c is K2CO3?
Is the periodic table allowed to be used on the tests?
What can I use instead of red cabbage in the chemistry experiments?
What help do you have for the calorimetry problems?
What is an isotope?
What is sodium hypochlorite (in bleach), and what happens when it is mixed with ammonia?
What is the blue green stuff formed in Experiment 2.2?
What kind of dishwashing liquid should I use for Experiment 7.1?
When I try to determine polar or non-polar, my Lewis structures do not lead me to the same conclusions as in the book. Why, for example, is CO2 non polar?
Where are the MicroChem experiments?
Where are the sample calculations for Experiment 7.1?
Why can't ultraviolet rays be deflected off the oxygen molecules back into space?
Why did Chemistry Experiment 12.1 not work out the way it was supposed to? The temperature rose during melting, boiling, or both.
Why did the water and syrup layers mix in Experiment 6.4?
Why does the amount of CaCO3 change in On Your Own 15.10a? I thought changes in solids did not affect an equilibrium.
Why do gaseous solutes decrease in solubility with increasing temperature?
Why don't antifreeze makers use ionic solutes to make antifreeze? With the higher "i," ionic solutes would protect against freezing better than the polar solutes they use now.
Why is the answer rounded to 2 x 10^3 J/g°C in Module 12, Practice Problem 10?
