Denzel Washington

 What is something you learn from the video?

I learned that the hard you try becomes what you want , one day you will succeed in the process of becoming what you want . Also he said that one day he was helping his mom , because she owns a hair salon store. And whale he was working he keeps looking in the mirror and the old lady keeps staring at her and she said “ young boy I have a prophecy , A spiritual prophecy , You are going to travel the world and speak to millions of people” but he's think how when he failed his education , and his prayers was answered ………. But then the old lady was right and one day he became a successful businessman .

What is something you see that can change your life ?

Something about the video that can change my life is that if you fail that fail will one day become successful if you try harder and never giving up on you dreams and goals, Finally one day all you want will be success

Diffrent types of gas experiments

Testing for Hydrogen Gas

Metal + Acid = metal salt + hydrogen

Magnesium + Sulfuric Acid = magnesium sulfate + hydrogen 

Equipment: A test tube, a boiling tube, bunsen burner, wooden splint, a bottle of acid, a piece of metal, safety glasses.

Method:

• Light a bunsen burner

• Add your sample of metal to your test tube add sml of acid

• carefully invert the boiling tube above the test tube containing the metal and acid ( as shown in the diagram below)

• Hold the test tube together for a few minutes allowing time for the inverted boiling tube fill with gas

• When you think the tube is full, your lab partner should light a wooden splint.

• Carefully , but quickly, titl 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

Metal + acid = Metal Salt + Hydrogen (Poptest)

Metal + Oxygen = Metal Oxide

Metal Oxide + Hydrogen Peroxide = Metal Hydroxide + Oxygen ( Glowing Splint)

Making a Metal Oxide

Aim: To make a metal oxide and observe the different in properties of the product compared to the reactants

Equipment:A piece of magnesium, Bunsen burner, safety glasses, metal scissor tog

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 : When we light up the magnesium we had to look away because the light was to bright your eyes might get infected 

Testing For Carbon Dioxide Gas 

Aim: To show that carbon dioxide gas is produced  when a metal carbonate reacts with acid

Equipment: Two boiling tubes, delivery tube and bung, Bunsen burner, test tube rack,wooden splint, a bottle of acid, small amount of metal carbonate, test tube tongs safety glasses.

Method: 

• Light your 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 tube ready
• 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 as shown in the diagram below
• When you think the tube is full, your lab partner should light a wooden splint
• Carefully remove the boiling tube for 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 as we put the half of the tube the the lime juice it bubbled up and the lime juice kinda went cloudy.
