The third one because
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
The population decreases when the birth rate is less than the death rate.
1.) <span>2Na(aq)+2H2O(l)→2NaOH(aq)+H2(g),
Na is oxidizing agent and H is reducing agent.
2.) </span><span>C(s)+O2(g)→CO2(g)
C is an oxidizing agent
3.) </span><span>2MnO−4(aq)+5SO2(g)+2H2O(l)→2Mn2+(aq)+5SO2−4(aq)+4H+(aq)
Mn is reducing agent and S is oxidizing agent.</span>
Well I had to Google this one because I really was not sure.. so, if I am right.. it should be friction
Answer:
0.2335320064 mi/min
Explanation:
1 km/h = 0.0103561865 mi/min
1 mi/min = 96.56064 km/h
For conversion:
22.55 km/hr = 22.55 x 0.0103561865 mi/min = 0.2335320064 mi/min
