ANSWER IS CONDUCTION. HOPE THIS HELPED!
Answer:
Initial Speed ____4m/s. Final Speed ______6m/s. Time ______5 seconds . Acceleration =________0.4m/s²
Explanation:
The acceleration is the rate of change of velocity during time t .
acceleration = Final velocity- Initial velocity/ Time
= Vf- Vi/ t
a = Δv/ Δt
= 6m/s- 4m/s/ 5s
= 2m/s/ 5s
= 0.4m/s²
It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.
If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.
Answer:
when sodium reacts with chlorine atoms, sodium will give an electron which is negative charged to chlorine.it makes sodium(+) and chlorine (-)..then sodium will attract chlorine to form sodium chloride(NaCl)
2.54 moles of CaCl occupies 56.89 liters volume
Explanation:
- Each mole of any gas occupies 22.4 liters volume at STP.
- STP is defined as the standard temperature and pressure and those standard values are zero degree and one atmospherics pressure
- 22.4 liters is a constant number as Avogadro's number which is nothing but 6.022*
. - Hence, to convert 2.54 moles just multiply it with 22.4 L
- That is, 22.4*2.54= 56.89 L
- So, 2.54 moles of CaCl occupies 56.89 L volume space
