The average speed : 3.07 m/s
<h3>Further explanation</h3>
Given
d1 = 2 km
t1 = 9 min
d2 = 1.5 km
t2 = 10 min
Required
The average speed
Solution
Average speed = total distance : total time
total distance :
= d1+d2
= 2+1.5
=3.5 km
total time :
= t1+t2
= 9 min + 10 min
= 19 min
Average speed :
= 3.5 km : 19 min
= 0.184 km/min
= 3.07 m/s
Answer:
Cu(OH)2 + 2HCl → CuCl2 + 2H2O
Answer:
Carbon iv oxide + water - - carbonic acid
Explanation:
CO2 + H2O--H2CO3 (balanced equation)
Answer: The prokaryotic cell does not have a nucleus!
Explanation:
The final volume of the Oxygen O2 would simply be
equivalent to the overall volume of the final mixture. This is because gases
would occupy every space of its container. So in this case, the volume of CO2
and O2 would be the same and it would be 30 L. What would be different is the
partial pressures of each.
Answer:
