Answer:
4 moles
Explanation:
= 
= 2 (moles)
CH4 + 2O2 → CO2 + 2H2O
1 : 2 : 1 : 2
2 (moles)
⇒ 
= 2 × 2 ÷ 1 = 4 (moles)
Answer:
pOH = 9.
Explanation:
The inverse relationship between the pH and pOH of any given solution can be written as:
pH = 14 - pOH
Or conversely:
pOH = 14 - pH
With the above information in mind we can <u>use the given pH to calculate the pOH</u>:
pOH = 14 - pH
pOH = 14 - 5
pOH = 9
Thus, black coffee has a pOH of 9.
The question is incomplete, the complete question is;
A block is pulled 0.90 m to the right in 2.5 s. What is the blocks average speed to the nearest hundredth of a m/s
Answer:
0.36 m/s to the hundredth place
Explanation:
Now let us remember the definition of speed. Speed is defined in physics as distance/time.
Here we have the distance as 0.9 m
We have the time as 2.5 s
Hence the average speed is obtained from;
Speed = 0.9/2.5 = 0.36 m/s to the hundredth place
It would be a synthesis reaction
