Answer:
12 mi/h
Explanation:
Step 1: Given data
Step 2: Convert "d" to miles
We will use the conversion factor 1 mi = 1.60934 km.
6 km × 1 mi/1.60934 km = 3.7 mi
Step 3: Convert "t" to hours
We will use the conversion factor 1 h = 60 min.
19 min × 1 h/60 min = 0.32 h
Step 4: Calculate the average speed of the runner (s)
The speed is equal to the quotient between the total distance and the time elapsed.
s = d/t
s = 3.7 mi/0.32 h = 12 mi/h
The soda an air is most likely bubbling up and is going to explode.
Answer:
64.17 Moles of Au
Explanation:
(atoms and particles are the same)
3.85 x 10 ^25 x (1 mol
/6.02 x 10^23)
3.85 / 6 = .64166
.6416 x 10^2 = 64.166
If you round up the answer you will get 64.17

Answer:
Cesium and Neon
Explanation:
Remember, Neon is a noble gas, also called an inert gas. It does not react really to form compounds. Although chlorine is only one column to the left of neon, it is very reactive and ready forms a salt when combine with sodium. The other elements have similar reactivities to each other. Only Neon is a non-reactive choice.
