B. providing a moderate, livable climate. The atmosphere basically means the canopy that shields us. If it isnt moderate or doesnt have livable climate, I dont think we would be able to survive. :|
Answer:
42) 76
b)70
Explanation:
52) because you don't want to confuse different units. one ex)1cm is 1/ 100 of a meter
55) 1 km=1,000 meters
b) 10 decimterers = 1 meter
56)The SI standard for length is the meter the standard for volume is the cubic decimeter
ex) 1cm³=1mL
57) The two scales are the same. but there are no negative temperatures in Kelvin. 0 Kelvin is the lowest temperature possible.
0 Kelvin= -274.5 Celsius
The answer to this question is <span>OH- + HA ⇒ A- + H2O</span>. The conjugate acid in the buffer, HA, neutralizes added strong base, OH-.
The beaker of acetic acid will cool more quickly.
The specific heat capacity of acetic acid is about half that of water.
Thus, it takes twice as much heat gain (or loss) in acetic acid to cause a given change in temperature.
If everything else is constant and heat is being lost at the same rate, the temperature of the acetic acid should drop twice as fast as that of water.
One calorie is equal to approximately 4.2 joules.
