Answer:
Title: Effect of soda color on the choice of Allison's friends.
Independent variable: Color of Soda
Dependent variable: Friends' choice/Number of friends that chose a particular soda
Please find the data table attached as an image.
Explanation:
A data table is used to organize the data recorded after an experiment. The data table shows the title of the experiment, which is written directly above the table. It also shows the independent variable (on the first column) and the dependent variable (on other columns to the right).
- In this experiment, the title of the data table can be written as EFFECT OF COLOR OF SODA ON THE CHOICE OF ALLISON'S FRIENDS.
- The independent variable is the manipulated or changed variable, which is the COLOR OF SODA in this case.
- The dependent variable is the variable that is measured in an experiment, which is the NUMBER OF FRIENDS THAT CHOSE EACH SODA in this case.
This is mind numbing, but I got you.
3NaOH + 1FeCl<em>3</em> = 1Fe(OH)<em>3 </em>+ 3NaCl
3Mg + 2H<em>3</em>(PO)<em>4</em> = 1Mg(PO<em>4</em>)<em>2</em> + 3H<em>2</em>
We find out the molar mass of NH₃.
atomic mass (N)=14 u
atomic mass (H)=1 u
atomic weight (NH₃)=14 u + 3(1u)=17 u
Therefore the molar mass of NH₃ will be: 17 g/mol
Then:
1 mol of water=18 g
2) We know that:
1 mol of any substance=6.022 * 10²³ particles.
3)We calculate the mass of 8.00 *10²² molecules
18 g of water----------------------------6.022*10²³ molecules
x---------------------------------------------8.00*10²² molecules
x=(18 g of water * 8.00*10²² molecules) / 6.022 * 10²³ molecules=2.39 g
Answer: the mass of 8.00 *10²² molecules of NH₃ would be 2.39 g.
B. the shape of a molecule determines its properties and interactions
<span> I suppose carbon dioxide produced from burning coal and oil can be recycled and converted to methanol. i hope this answers your question</span>
