The 2013 Rolls Royce Ghost Alpine has a top speed of 155 miles per hour. Calculate the speed in centimeters per second.
AutoChina Shanghai 2013 also plays host to the world debut of the latest Bespoke Collection from the world’s pinnacle super-luxury marque.
The Alpine Trial Centenary Collection celebrates an extraordinary moment in Rolls-Royce and automotive history. A century ago this June, four Rolls-Royce Silver Ghosts embarked on the Austrian Alpine Trials, the most arduous test of automotive endurance of the time.
In performing without fault over 1820 gruelling miles of near impassable mountain terrain, the Rolls-Royce works team and privateer entrant James Radley helped cement the marque’s reputation for peerless reliability and mechanical excellence, a reputation the company proudly retains today. In doing so establishing the legend of Rolls-Royce as maker of the ‘Best Car in the World’.
This limited edition of Rolls-Royce Ghosts feature exquisitely crafted design cues that pay tribute to these extraordinary motor cars. The exterior paint hue, for example takes close inspiration from Radley’s Silver Ghost, a car that stands side-by-side with the 2013 model in Shanghai.

Sodium benzoate, the sodium salt of benzoic acid, is used as a food preservative. A sample containing solid sodium benzoate mixed with sodium chloride is dissolved in 50.0 mL of .5 M HCl, giving an acidic solution (benzoic acid mixed with HCl ). This mixture is then titrated with .393 M NaOH. After the addition of 46.50 mL of the solution, the pH is found to be 8.2. At this point, the addition of one more drop ( .02 mL) of NaOH raises the pH to 9.3 . Calculate the mass of sodium benzoate (NaC6H5COO) in the original sample. (Hint: At the equivalence point, the total number of moles of acid [here HCl] equals the total number of moles of base [here, both NaOH and NaC6H5COO]

A student dissolves 14.8 g of ammonium nitrate (NH4NO2) in 300. g of water in a well-insulated open cup. He then observes the temperature of the water fall from 20.0°C to 15.0°C over the course of 4.3 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:
NH4NO3(s) → NH4+(aq) + NO3^- (aq)
Required:
a. Is this reaction exothermic, endothermic, or neither?
b. If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case.
Answer:
a. Endothermic
b. 6586J are absorbed.
Explanation:
a. When the reaction occurs, the temperature is decreasing from 20.0°C to 15.0°C, that means the reaction is absorbing heat and is endothermic.
b. To find the heat absorbed we must use:
Q = -m*ΔT*C
Where Q is change in heat,
m is the mass of solution (300g + 14.8g = 314.8g)
ΔT is change in temperature (15.0°C - 20.0° = -5.0°C)
And C is specific heat of the solution (4.184J/g°C assuming is the same heat than the heat of pure water).
Replacing:
Q = -314.8g*-5.0°C*4.184J/g°C
Q =
6586J are absorbed
The pressure 15.0 m under water is 248 kPa.
What is this pressure in torr
Answer:
1860 torr
Explanation:
In order to convert from kPa to torr, we are going to use the following conversion factor:
1 kPa = 7.5 torrNow we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:
248 kPa * [tex]\frac{7.5torr}{1kPa}[/tex] = 1860 torrThis means that the answer is 1860 torr.
