A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M. In a neutral solution, then, pH = pOH = 7.
Answer:
The annual production of carbon dioxide is .
Explanation:
Distance covered by each car = 5790 miles
Rate of consumption of gasoline =24. mile/gal
For every 24.1 mile 1 gallon of gasoline is used
Gasoline used by a single car by travelling 5790 miles =
Number of cars in the United states = 40.0 million =
Total gallons of gasoline consumed by 40 million cars =
1 gallon of gasoline produces = 9.50 kg of
Then of gasoline will produce:
of
The annual production of carbon dioxide is .
5.426 x molecules are there in a deep breath of air whose volume is 2. 35 L at body temperature 36 C and a pressure of 740 torr.
Explanation:
Data given:
volume V = 2.35 L
Temperature T = 36 Degrees or 273.15 + 36 = 309.15 K
pressure P = 740 torr OR 0.973 Atm
R = 0.08205 L atm / mole K
n (number of molecules of gas)= ?
The formula used will be
PV = nRT
Putting the value of given variables in above equation:
n =
=
= 0.0901 moles
According to Avagadro' s law that gases at equal volume, temperature and pressure contains same molecules.
number of molecules:
number of moles x avagadro number
0.0901 x 6.02 x
= 0.54 x
= 5.426 x molecules.
Answer:
c
Explanation:
i think soo. but not sure.
I would guess A, varies with pH.
