O B. conjugate acid to conjugate base
O C. conjugate base to conjugate acid
OD. solute to the amount of solvent in a solution
Answer:
Option C
Explanation:
A buffer aqueous solution consists of
a) either a weak acid along with its conjugate base
b) or a weak base along with its conjugate acid.
This is used to prevent change in the pH of a solution whenever an acid or a base is added. The pH of a buffer depends upon the ratio of base to acid and this ratio is determined by the Ka value and Henderson-Hasselbalch equation. An ideal buffer has equal amounts of acid and conjugate base
Hence, option C is correct
Principal (shell) quantum number - n
b) It is an endothermic reaction.
c) It produces carbon dioxide.
d) It occurs in animals.
Atomic theory is
a) subject to change if new information is discovered.
b) a solution to the problem of differing isotopes.
c) unchangeable.
d) a descriptive table that lists all of the elements.
Two nonmetals from Group 16 are likely to form a(n)
a) metallic bond.
b) double bond.
c) ionic bond.
d) covalent bond.
a)amino
b)carboxyl
c)halide
d)hydroxyl
Answer:
1151.08miles/h
Explanation:
The given speed is 515 m/s
To convert meters per second to miles per hour:
Convert meters to miles: 1 m = 0.000621371 miles
Convert seconds to hours: 1 hr = 3600 s
Plug into the formula: miles/hr = (m/s) * (0.000621371 miles/m) * (3600 s/hr)
Plugging in the numbers: miles/hr = (515 m/s) * (0.000621371 miles/m) * (3600 s/hr) miles/hr = 1151.08miles/h
Therefore, the average speed of a nitrogen molecule in air at 25 °C converted to miles per hour is 1151.08miles/h.
To convert the average speed of a nitrogen molecule in air from meters per second to miles per hour, first convert the speed from meters per second to kilometers per hour, and then convert from kilometers per hour to miles per hour.
To convert the average speed of a nitrogen molecule in air from meters per second to miles per hour, we can use the conversion factor 1 mile = 1609.34 meters and 1 hour = 3600 seconds.
First, let's convert the speed from meters per second to kilometers per hour. We divide the speed in meters per second by 1000 to get the speed in kilometers per second and then multiply by 3600 to get the speed in kilometers per hour. This gives us a speed of approximately 1850 km/h.
Next, we convert the speed from kilometers per hour to miles per hour by dividing the speed in kilometers per hour by 1.60934. This gives us a speed of approximately 1150 mph.
