When writing an aim, it should be in the format of the Goal (what do you want to achieve) and the Means (how you plan to achieve it).

Read over Exercise 6 in your lab manual to assist you with completing the aim of this experiment. Record the aim in your laboratory notebook, so that you will be able to address it when you write the conclusion for your lab report.

Aim:

To determine the composition of Monash University's new  by using  and a  curve of change in  vs mixture composition.

If you have a mixture composed of 0.87 g Citric Acid (CA) + 1.13 g Sodium Bicarbonate (SB), determine:

a) The mass fraction of CA in the mixture (m_CA/m_Total) (report answer to 2 decimal places) 

b) The mole fraction of CA in the mixture (n_CA/n_Total) (report answer to 2 decimal places) 

c) The molar ratio (n_SB/n_CA) (report answer as an integer) 

Based on your findings in

Q11, what is the heat lost by the calorimeter (i.e. the surroundings)? 

Note: q(reaction) + q(calorimeter) = 0

Sodium bicarbonate reacted

with citric acid in 1 L of water, resulting in a temperature decrease of 10.11

The specific heat capacity

of water is 4.184 J K

 q(reaction) =

-mcΔT 

where m = mass of water

The specific heat capacity

of water is 4.184 J K

Determine the number of moles in:

 a) 0.87 g Citric Acid, CA (M = 192.124 g mol^-1)

 b) 1.13 g Sodium Bicarbonate, SB (M = 84.007 g mol^-1)

A sample of 0.87g citric

acid and 1.13g of sodium bicarbonate was added to 30mL deionised water in a

coffee cup calorimeter with an initial temperature of 22 

1. What

is the change in temperature?

2. Based on the temperature

change, what type of reaction is it?

What shouldn't you touch when you are setting up your calorimeter?

In a classroom containing metal and plastic chairs, people often say that the metal chairs feel colder than the plastic chairs. This is because:

A piece of iron railway track will get longer when it is in the hot sun, and that is why there are usually gaps between pieces of track.

When the track expands the iron atoms:

A molecule of gaseous dinitrogen tetroxide, N₂O₄, contains an N-N bond. The bond can break to form two molecules of gaseous nitrogen dioxide, NO₂.

Which of the following statements is true?
