Its a single Displacement reaction
<span>A metal is one which ionizes easily and gives electrons whencompared to other elements.
So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
Ans) 1.3 bison/mile
Soln:} See according to the question, Yellowstone National Park has an average of about 4500 bison living in it.
Area covered by Yellowstone park is 3472 miles.
So, to find the density of bisons living in Yellowstone Park we have to divide the no. of bisons by given area.
= 4500/3472
which is approximately 1.3 bisons per mile.
Therefore option a) is correct
Hope it helps!!!
Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Explanation:
Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.
13.5 Moles Kcl x 6.022 x 10^23 /1
= 8.12 x 10^24
whenever you need to find molecules just multiply moles by avogadro number
