Answer:
C4H3O
Explanation:
Data obtained from the question include:
Carbon (C) = 68.85%
Hydrogen (H) = 4.95%
Since the vaccine contains carbon, hydrogen and oxygen, the remaining percentage will be for oxygen. The percentage of oxygen will be:
Oxygen (O) = 100 - (68.85 + 4.95)
= 26.2%
The empirical formula for the vaccine can be obtained as follow:
Carbon (C) = 68.85%
Hydrogen (H) = 4.95%
Oxygen (O) = 26.2%
Divide the above by their individual molar mass as shown below:
C = 68.85/12 = 5.7375
H = 4.95/1 = 4.95
O = 26.2/16 = 1.6375
Next, divide by the smallest number as shown below:
C = 5.7375/1.6375 = 4
H = 4.95/1.6375 = 3
O = 1.6375/1.6375 = 1
Therefore, the empirical formula for the vaccine is C4H3O
SORTING METHOD can easily be used to separate a mixture of steel ball bearing and marbles. This separation method is suitable because the two substances that are mixed together have big sizes, so it is easy to separate the two by hand picking the particles. Sorting method is usually used as a separation technique when the size of the mixture is big and the mixed substances are in the same state.
I believe it's b) distillation
All you have to do is explain the relationship between years and inches. The most rain was in 2004 with 10 inches and the least was in 1998 with 4 inches. In recent years there has been more rain than in the past. For the analysis just summarize that.
<span>Erosion by wind or water transports the rock particles and sediments to other sooner or later hitting the ocean.then the rocks form together to make sediment rock! :D</span>
