Answer:
PV=nRT
Explanation:
T=PV/nR
P=5.6atm n= 4 mol V=12 L R =.082Latm/K mol
T= (5.6 atm)(12 L)/(4 mol)(.082Latm/K mol)
T = 205 K = -68 C
b)this base ionizes slightly in a aqueous solution
c)this is a strong base
d)an aqueous solution of this base would be acidic

Answer:
The time saved on a ten mile trip by traveling at 60 mph instead of 55 mph is 54 seconds
Explanation:
Velocity is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction. So velocity is the change in position of a body over time:
The mile per hour (mph) is a unit of speed measurement that expresses the number of international miles traveled per hour.
From the definition of speed it can be deduced that the time it takes to travel a certain distance at a constant velocity is:
velocity*time=position
Then, if the position is 10 miles and the velocity is 55 mph:
time=0.1818 hours
If 1 hour is 60 minutes, the time can be expressed as:
time=0.1818 hours*60 minutes= 10.90 minutes
The position is now constant at 10 miles, but the speed is 60 mph. So the time it takes to travel that distance at that speed is:
time=0.166 hours
If 1 hour is 60 minutes, the time can be expressed as:
time=0.166 hours*60 minutes= 10 minutes
To calculate the time you will save, the subtraction of both times obtained is performed:
10.9 minutes - 10 minutes= 0.9 minutes
If 1 minute is 60 seconds, the time can be expressed as:
0.9 minutes*60 seconds= 54 seconds
The time saved on a ten mile trip by traveling at 60 mph instead of 55 mph is 54 seconds
Time = Distance/Rate
for 60 mph
Time = 10 miles/60 mph
= 0.1666 * 60 minutes = 10 minutes
for 55 mph
Time = 10 miles/55 mph
= 0.181818 * 60 minutes = 10.90 minutes
2H2O yields 2H2 + O2
H2 + Cl2 yields 2HCl
2Li + CaO yields Li2O + Ca
CH4 + 2O2 yields CO2 + 2H2O
Answer : The correct option is, (3)
Explanation :
Isomers : It is defined as the molecule that has the same chemical formula but it has the different structures.
Same chemical formula means that the same number of elements are present in both the compounds.
In option 1,2 and 4, both chemical formula and the structure are different. So, the option 1 compounds are not the isomers of each other.
In option 3, the chemical formula is same but the structure are different. So, the option 3 compounds are the isomers of each other.
Hence, the correct option is, (3)
