The si unit for energy is the joule (j), which is equal to the kinetic energy possessed by a 2.00-kg mass moving at 1.00 m/s. convert this velocity to mph (1 mi=1.609 km). (a) 4.47 x 10^-7 mph (b) 5.79 x 10^6 mph (c) 5.79 mph (d) 0.0373 mph (e) 2.24 mph

e) 2.24 mph

Explanation:

⇒v = 1.00 m/s * ( Km / 1000 m ) * ( 3600s / h ) * ( 1 mi / 1.609 Km )

⇒ v = 2.237 mi/h ( mph )

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
