Different types of gas experiments

The Pop test 

Metal + Acid

Equation

- metal + sulfuric acid = metal salt + hydrogen.

Aim

-to show that hydrogen gas is produced when a metal reacts with acid

Equipment

-test tube

-boiling tube

-bunsen burner

-wooden splint

-bottle of acid

-a piece of metal

-safety glasses

Method

- light the bunsen burner

- add ou sample of metal to your test tube. Add 2 ml of acid

- carefully invert the boiling tube above the test tube containing the metal and acid.

- hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.

- when you think the tube is full, you lab partner should light a wooden splint

- carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Conclusion

- when we light the wooden splint with fire and put in the mouth of the tube it made a sound a popping sound.

Glowing Splint

Metal + Oxygen

Equation

metal oxide + hydrogen peroxide = Metal hydroxide + oxygen

Aim

-to make a metal oxide and observe the difference in properties of the product compared to the reactants

Equipment

-a piece of magnesium

-bunsen burner

-safety glasses

-metal scissor tongs

Method

-light the bunsen burner

-hold the piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the magnesium.

-place the other end of the magnesium into the bunsen flame(at the top of the blue flame)

-when the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes

Conclusion

We fire the magnesium and then it burn up into a real bright light for a few second. Then after that it turn into a white powder and its silver, grey, and kinda soft.

Lime water test

Metal Carbonate + Acid

Equation

metal carbonate + acid = metal salt + water + Carbondioxide

Aim

-to show that carbon dioxide gas is produced when a metal carbonate reacts with acid

Equipment

-2 boiling tube

-delivery tube and bung

-bunsen burner

-test tube rack

-wooden splint

-bottle of acid

-small amount of metal carbonate

-test tube tongs

-safety glasses

Method

-light the bunsen burner

-add a 'pea-sized' amount of the metal carbonate into one of the boiling tubes

-place this boiling tube into a test tube rack, ensure you have the bung and delivery

-add 5 mL of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube

-holding the other boiling tube with your tongs, capture the gas produced.

-when you think the tube is full your lab partner should light a wooden splint.

-carefully remove the boiling tube from under the delivery tube, taking care to keep it facing upright.

-insert the burning splint into the mouth of the test tube.

Conclusion

As soon we connected the lime water and the metal carbonate and acid with the delivery tube it reacted at that time. The lime water change its colour and its kinda like cloudy then back to it original colour.

Trashing Our Planet

What is the the Great Pacific Garbage Patch and where is it? 

-the great pacific patch is gradually as a result of ocean or marine pollution gathered by oceans currents. It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. It is located near Japan and the Eastern Garbage Patch.

How is it impacting the environment in a negative way?

-because the Great Pacific Patch and plastic pollution generally, is killing marine life. Seabirds and marine mammals are affected every year as well as many other species. For example: turtle often mistake plastic bag for prey such as jellyfish.

What is being done to help with this problem?

-Reuse plastic and try something new with it or create something with plastic that you can used. Stop throwing rubbish in the sea cause it is affecting marine animals and many other species in the sea.

 Problem about plastic pollution?

-Plastic pollution is the most common problem affecting the environment. It also threaten, ocean health, food safety and quality, human health, coastal tourism, and contributes to climate change. Plastic bottles which is the worst plastic is typically made from crude oil. These pollute the environment and pollute the air we breathe.

 What we could do to fix it?

-The best way is to reuse an single use plastic that you do not need. For examples (eg):takeout containers, straws, plastic bags, and purchasing, and carrying with you reuseable version of those product, including reusable grocery bags, produse bag, bottles, coffee cups.
