Answer:
16.6 km/h
Step-by-step explanation:
Speed = distance/time
= 400.0 m/86.8 s
= 4.608 m/s Convert kilometres to metres
Speed = 4.608m/s × (1 km/1000 m)
= 0.004 608 km/s Convert seconds to hours
Speed = 0.004 608 km/s × (3600 s/1 h)
= 16.6 km/h
Let the ratio of grams of hydrogen per gram of carbon in methane be M, we know that:
M = 0.3357 g / 1 g
Next, lets represent the grams of hydrogen per gram of carbon in ethane be E. The final piece of information we have is:
M / E = 4/3
If we cross multiply,
3M = 4E
Now, substituting the value of M from earlier and solving for E,
E = (3 * 0.3357) / 4
E = 0.2518
There are 0.2518 grams of hydrogen per gram of carbon in ethane.
Answer:
b. ion-ion
Explanation:
When NaCl dissolves in water , it dissociates completely into the corresponding ions , i.e. , Na⁺ and Cl⁻ ,
Since , the charges have complete positive and negative charges , hence , they interact with each other via ion - ion interaction , i.e. the interaction between the positive and negative charges , is referred to as ion - ion interaction .
Hence , the correct option is b. ion-ion interaction .
