Answer:
(-14+3/2b) - (1+8/2b) goes with -15-5/2b
(5+26)+2b+3/2) goes with 4b+13/2
(-10+b)+(7b-5) goes with 8b-15
(7/2b-3)-(8+6b) goes with -5/2b-11
Step-by-step explanation:
The complete balanced chemical reaction is:
<span>C7H16 + 3O2
--> 7CO2 + 8H2O</span>
So 3 moles of oxygen O2 is required for every 1 mole of
C7H16. In the same manner, 3 molecules of O2 is required for every 1 molecule
of C7H16.
Answer:
<span>3 molecules O2 </span>
Answer:
A
Step-by-step explanation:
The slope formula is y=mx+b. Y is a variable. m is the actual slope. It tells you how much the x will move. For example, if a slope was 2x, x would move up 2 and over 1. If the slope was 1/2 x, x would move up 1 and over 2. A way to remember slope is rise over run. X is a variable. B is a point on the y-intercept that is will the line will start. An example is y=x+3. The y-intercept is 3 and x would move up one and over one.
Given :
C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.
To Find :
Two possible lengths for CD.
Solution :
Their are two cases :
1)
When D is in between C and E .
. . .
C D E
Here, CD = CE - DE
CD = 15.8 - 3.5 cm
CD = 12.3 cm
2)
When E is in between D and C.
. . .
D E C
Here, CD = CE + DE
CD = 15.8 + 3.5 cm
CD = 19.3 cm
Hence, this is the required solution.
