Answer:
See explanation
Explanation:
distance = 3 kilometres
time = 30 minutes or 0.5 hours
speed = distance/time = 3/0.5 = 6 Kmhr-1
Average speed is given by total distance covered divided by the total time taken while the instantaneous speed is the speed of an object at a particular instant or moment in time. Average speed refers to the whole journey while instantaneous speed refers to a particular point or instant in the journey.
distance= x
time = 3 hours
speed = 50 miles per hour
speed = distance/time
distance = speed * time
distance = 3 * 50
distance = 150 miles
Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.
Low pressure and high temperature
The shot answer for this question is (a) True
Volume = V = 250ml = 0.25 L
<span>M = 0.135M </span>
<span>Molar mass of AgNO3 = 108+14+3*16 = 170 </span>
<span>M = mole/V </span>
<span>mole = 0.135*0.25 = 0.03375 mole </span>
<span>mole = mass/molar mass </span>
<span>mass = 0.03375 * 170 = 5.7375 gr</span>
