Step 1 – Remove blazer and put goggles on for health and safety reasons.
Step 2 – Collect the following equipment –
Thermometer – to check the temperate
Conical flask – to hold acid
1 litre breaker – contain water
Measuring cylinders x2 50ml 25ml
Blanco – to weight out the marble chips
Marble chips CaCO3 – which react with Hydrochloric acid
Stopwatch – to time when the reaction starts
Delivery tube – to pass the air
Camp stand – to hold the equipment
Boson – it heats up the water
Tripod – to hold the beaker at a certain height that has the most heat
Ice – to cool down the water of a certain temperate
Test tube holder – so you don’t burn your hand and it is safe.
Step 3 – Set up all the equipment.
A- Clamp Stand. B- Measuring tube (25ml) C- Delivery tube
D- Conical flask E- Reaction “what’s happening” F- Thermometer
G- Beaker H- Boson I- Tripod
J- Water K- 1 litre beaker
Step 4- My partner weighed the marble chips on the Balance, the amount we used was 1g.
Step 5- I poured the Hydrochloric acid into the 50ml measuring tube, the amount we used was 40ml.
Step 6- I filled the measuring tube with water and put my thumb over the top and press hard so there was no air in it.
Step 7- I filled the large beaker up with water and placed it near the clamp stand.
Step 8- I used the measuring tube and turned it over and put it in the beaker which has water in it then made sure there was no air trapped in the measuring tube.
Step 9- Make sure the delivery tube is fitted so the air that been created by the marble goes in the tube and not in the air.

...eriment I could improve many things like changing the marble size, time and heat.
The marble we used in the start of the experiment was too large which mean the rate of reaction was dropped really low, to overcome this problem we made sure we had small marble so that the experiment can be relievable and have a good set it result.
Another problem where found that time keeping from the experiment we were doing, the times weren’t spot on or we didn’t stop it in time, or too early.
You can see from the table at 35 the average time did not match the time on after and before temperature the reason could be we didn’t check the temperature correctly or maybe we had large rocks that the surface are is too little or we did not read the time correctly or we didn’t stop it in time, to overcome this problem we be to double check the time and take extra care with timing.

- How Concentration Affects The Speed Of A Chemical Reaction Aim --- To investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. Preliminary Research -------------------- The rate of a chemical reaction is the measure of how fast the reaction takes place. In a reaction particles must collide and overcome the fixed amount of energy for the reaction to take place. This energy is called the activation energy. The rate of reaction depends on four factors: « Temperature - An increase in temperature produces an increase in rate of reaction.... [tags: Papers]

- Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different concentrations of acid reacting with magnesium in two separate experiments, which will hopefully prove this initial prediction.... [tags: Papers]

Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips
- Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips Introduction ============ There are many factors that will affect the rate of reaction between hydrochloric acid and calcium carbonate. Some of them are as follows: * Temperature - If the temperature is higher, then the molecules in the solution have more energy, causing them to move around more which would mean they would react faster. * The surface area of the calcium carbonate - If the calcium carbonate is in a sphere shape, then there is not as much surface area than there would be if it was in a flat cuboid shape or perhaps...

Investigating the Effect of Concentration on the Speed of the Reaction Between Hydrochloric Acid and Sodium Thiosulphate
- Investigating the Effect of Concentration on the Speed of the Reaction Between Hydrochloric Acid and Sodium Thiosulphate Prediction: My prediction is, the higher the concentrations, the faster the reaction will occur in my experiment to make the x on the sheet on paper disappear. When there is more concentration, the molecules gain kinetic energy & the process of collision occurs. This causes the reaction to happen more rapidly therefore making a cloudy substance much quicker.... [tags: Papers]

- Reaction Rate is the measure of how quickly an organism’s neurons can communicate or react to a type of stimulus. In other words it is how fast an organism’s neurons can send signals to the brain and from the brain. The anatomy of a classic neuron is rather simple. A classic neuron comprises of a body and a tail. The body has a nucleus with arms protruding outwards, these are called dendrites. Dendrites are the postsynaptic neurons for synaptic communication, they receive neurotransmitters from the presynaptic neurons.... [tags: neuron reaction]
