CO2 molecular shape: hybridization of the central atom write in normal characters sp, sp2, sp3 name: number of sigma bonds: number of pi bonds:

Give the following details about HBr total number of electrons: name: number of sigma bonds: number of pi bonds:

Solutions are really liquid-phase mixtures. Briefly choose the best identification of the type of intermolecular force between the solute and solvent in a water solution that has CaCl2 dissolved in it.

The number of calories in 3.0 g of glucose (blood sugar) is listed as 10.0 cal. If 15.0 g of glucose is reacted in a calorimeter, such that all of the energy is released and captured in a 1,000.00-gram water bath surrounding the calorimeter, what is the expected final temperature of the water following the reaction if the initial water temperature is 21.0 °C? The specific heat of water is 4.18 J/g °C or 1.00 cal/g °C. Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter your answer in the text box below.

A 2.5-gram sample of french fries is placed in a calorimeter with 500.0 g of water at an initial temperature of 21 °C. After the combustion of the french fries, the water has a temperature of 48 °C. What is the caloric value (kcal/g) of the french fries?

Give the name and symbol for your favorite element and briefly explain why it has a special place in your heart. Make sure you spell the name correctly and give the proper symbol for the said element.  Example: I like xenon (Xe). It has a cool name, and balloons filled with xenon drop like rocks. Not to mention those bright headlights on expensive cars.

Now that you have drawn the Lewis structure, give the following details about Formaldehyde (CH2O) continued bonding electron pairs on O atom: nonbonding electron pairs on O atom: shape of the molecule: hybridization of the central atom:
