ساینمنت انگلیسی(38308)*

شرح پروژه

سلام وقت بخیر  میخواستم بدونم شما اساینمنت انگلیسی هم انجام میدین؟  شیمی به زبان انگلیسی  1) Choose one of the following chemical

reactions to investigate.

Metals reacting with acids as follows:

X (S) + H2SO A (ag)

-› XSO A (ag) + H2 (g)

Carbonate or carbonate salts react with

acids as follows:

XCO3 (S) + 2 HCI (aq)

> XCI2 (ag) + H20

(g) + CO2 (g)

Hydrogen peroxide decomposes as follows:

2 H202 (aq)

- 2 H20 (1) + 02 (g)

2) Write an appropriate testable question that

you will attempt to answer in this investigation.

Your question must state the manipulated and

responding variables (i.e. the independent and

dependent variables).

Note

- you will plan to investigate the affect of

two of the following factors

- the concentration

surface area, temperature, and catalysts.3) Write a hypothesis outlining how the factor or

factors you have chosen affect chemical reaction

rates. Then, predict the results of your

investigation based on this hypothesis.

4) Identify all major independent, dependent, and

controlled variables in your investigation.

5) Describe your experimental set-up and

procedure, including the independent,

dependent, and controlled variables. Make sure

to include the following information:

Basic safety precautions required in a lab

The independent, dependent, and

controlled variables

All necessary chemicals and equipment

Safety information for the chemicals being

used

- in this section, you will include

appropriate safety labels.
