The final tutorial in our series on gas stoichiometry will focus on an equation that combines different theories to comprehensively examine the properties of gases. However, we will soon see why this equation isn’t `ideal’ . … More Gas Stoichiometry: The Ideal Gas Law
In the previous tutorial, we examined how to calculate the mass, amount and volume of a gas at standard temperature and pressure (STP). In this tutorial, we are going to calculate the same variables for gases in isolation and as part of a reaction – but at room temperature and pressure (RTP). … More Gas Stoichiometry: RTP
When it comes to working out the mass, amount or volume of a gaseous substance in isolation or in a reaction, you have to consider the properties of temperature and pressure.
The first part of this tutorial on gas stoichiometry will focus on calculating the volume (in dm3 or litres), amount in moles and mass in grams of gaseous substances in isolation or within a reaction at standard temperature and pressure (STP). … More Gas Stoichiometry: STP
Those of you who have been following my blog since the beginning (which seems long ago but was actually less than a year ago) may notice a slight difference on the site and the associated social media pages. I have decided to change the name of the blog to ‘Science and Joe’.
This new name is meant to reflect the majority of the content on this blog (i.e. sciencey stuff). However, I will also be writing some lifestyle posts, mainly about being a mature student and how I’m trying to lead a healthier and more balanced life.
Welcome to ‘Science and Joe’: it’s the same house with a new front door. … More Same Stuff: Slightly Different Name
Last week I had the pleasure of attending a science festival in which some amazing individuals shared their work and thoughts to an audience of proud science geeks. I found each talk so inspiring and it has prompted me to think even more about the broad range of career options available in clinical, laboratory and other environments.

In this tutorial, we are going to go through how to calculate the percentage yield and the atom economy of a reaction. … More Percentage Yield and Atom Economy
Highlighter pens, slightly crinkled lecture notes and trying to remember a piece of information that entered your brain about 8 months ago but has since decided to take a vacation somewhere else: these are just some of the features of revision during exam season – for me anyway. … More Exam Season: Revision-Life Balance
In this first part of the third tutorial of the trio of tutorials on stoichiometry on this blog, we are going to be going through: what a limiting reactant is and how to identify one in a chemical reaction; how to calculate the amount of product produced using a certain amount of a limiting reactant and how to identify the excess reactant and work out how much excess is left over from a chemical reaction. … More Limiting and Excess Reactants
In this tutorial, we are going to be working out the number of particles – which could be atoms, molecules or formula units – of a substance that are acting as either a reactant or a product of a chemical reaction. … More Determining the Number of Particles of a Reactant or a Product of a Chemical Reaction (with and without Conversion Factors)
In this tutorial, we’ll go over some mole ratio questions while will involve calculating the amount in moles of a reactant or product using the amount in moles of a substance on the other side of a balanced chemical equation.
We are also going to be going over how to calculate the number of particles (atoms, molecules or formula units) that are acting as a reactant or is a product of a chemical reaction. This will be discussed in next tutorial – entitled ‘Determining the Number of Particles of a Reactant or a Product of a Chemical Reaction (with and without Conversion Factors)’. … More Mole Ratio Questions (with and without Conversion Factors)
