Answer:
The Final Answer would be 14.9987.
Step-by-step explanation:
Given:
We need to Subtract the above number.
Since the larger number is standard Notation form and smaller number is in Scientific notation form
So first we will convert the Scientific notation Number in standard Notation form we get;
Now Subtracting the smaller Number from larger number we get;
Hence The Final Answer would be 14.9987.
(3)(-5) = -15
Answer : -15
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
Answer:
22½ in³ or 22.5 in³
Step-by-step explanation:
V=bwh
V=5(3)(1.5)
V=15(1.5)
V=22.5
3=6 ; 6+8=180
(2x-5)+(x+5)=180
X=60
6=115, 8=65
Hope that answer can help you!
