Answer:
304.51.
Step-by-step explanation:
Your question is kind of confusing but I think your question is 8.23 x 37. The answer to that is 304.51.
For this case, we have that by definition, if two lines are parallel, then their slopes are equal, that is, it is fulfilled:
So, if we have:
Where 
This line has 
So, a line parallel to it will have:
Answer:
Answer:
22.4 litres
Step-by-step explanation:
Reaction:
2Mg (s) + O2 (g) → 2 MgO (s)
From the reaction, we know that 2 moles of Mg (s) react with 1 mol of O2
STP conditions mean:
- absolute temperature of 273.15 K
- absolute pressure of 1 atm
Using the equation of state for ideal gases:
PV = nRT
where P is the absolute pressure, T is the absolute temperature, n are the moles, V is the volume, and R is the gas constant = 0.082 atm*L/(mol*K). Solving for V and replacing:
V = nRT/P
V = 1*0.082*273.15/1
V = 22.4 litres
