Answer:
OZ2 is the oxygen and DY5 is Dynamite
Explanation:
First convert each mass to moles by dividing by the molar mass.
0.347g Oxygen = 0.022 moles
0.260g Carbon = 0.022 moles
1.537g Chlorine = 0.043 moles
Divide each by smallest mole vale (0.022)
Oxygen = 0.022/0.022 = 1
Carbon = 0.022/0.022 = 1
Chlorine = 0.043/0.022 = 2
Therefore the empirical formula is COCl2
The answer for 1/0.00032 in standard scientific notation is 3.125 * 10^3.
<u>Explanation</u>:
For conversion of the given number in scientific notation follow
a * 10^b
The steps to see how 3,125 written in scientific notation as follows.
Step 1
To find a, The number is moved right to one decimal place.
Original Number: 3,125
New Number: 3.125
Step 2
Now, to find b, Find the decimal count on the right side.
New Number: 3 .1 2 5
Decimal Count: 1 2 3
There are three places found.
Step 3
Now we can reconstruct the number into scientific notation.
The Scientific notation is: a x 10^b
a = 3.125
b = 3
Now writing the whole thing:
3.125 x 10^3
Step 4
Check your work:
10^3 = 1,000 x 3.125 = 3,125.
