Making salts

Aim: To produce sodium chloride salt by carrying out a neutralisation reaction

1.  using the measuring cylinder measure 10 ml of HCI and pour it into your 50 ml beaker. add dilute NaOH a few at a time while stirring with a glass rod. 
2. Every 10-15 drops stop adding the NaOH  and use the glass stirring rod to transfer a drop of a solution to a spotting tile. Test it's pH using universal indicator.
3. Keep adding NaOH and test the solution by repeating step 2. As you get closer to neutral you may need to test the solution after every drop.
4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment needed

Neutralization

• A chemical reaction occurs when a acid and a base is mixed. The base stops the effect of the acid. This reaction is called neutralization. This is because a neutral solution is made if you add the right amount of acid and base  

• The aim is to identify the neutralization's reaction

In 10 wood we have been learning to use a gantt chart. A Gantt chart is a type of bar chart that shows a the project's schedule. This chart has the tasks that are to be done on the vertical (straight up and down) axis, and the time on a horizontal (across) axis.

Here is my example of a gantt chart I done.

I start again with the blue because i had made a error in my build a boat project, which made restart

Just Three Of Us Left, Just Three

Three of us. Just three of us left. Only one will live to see the morning, as the circle gets smaller and smaller There goes one killed by a shotgun. now it's just just me and him and i have no clue where he is. exploding trees.
Rocks and previously built bases to get visual on the other player.
Then i see him saw through the sky like a rocket then deploying his paper parasol gliding towards me, i build myself a 1x1 base to protect myself he builds himself one to.
Resetting the play i start firing me grenade launcher hoping to destroy his base, then successful i fired my scar hitting him for 90 before he defended himself with walls, then i new he was fully shielded. Launching one last grenade, i watched it lob over his building and landing perfectly beside him then exploding him there i have done it, i have a Victory Royale with 9 kills.
