Is there anymore to the question?
Explanation:
At convergent plate boundaries two plates are moving towards one another and different scenarios are in play.
Most importantly, at these margins the crust is being destroyed.
- At continental - continental crust margin, there is an uplift because the density of the two crust is similar and lesser than that of the mantle below.
- At continental - oceanic crust margin, subduction zones are found where the denser oceanic crust sinks beneath into the mantle.
- This is also the case with ocean - ocean convergence zone.
Some of the features found at this margin include, oceanic trenches, accretionary wedges, volcanic islands, earthquakes
There are six atoms in the carbon
To solve this problem, let us all convert the mass of
each element into number of moles using the formula:
moles = mass / molar mass
Where,
molar mass K = 39.10 g / mol
<span>molar mass Cl = 35.45 g / mol</span>
molar mass O = 16 g / mol
<span>and mass O = 13 g – 4.15 g
– 3.76 g = 5.09 g</span>
moles K = 4.15
g / (39.10 g / mol) = 0.106 mol
<span>moles Cl = 3.76 g / (35.45 g / mol) = 0.106 mol</span>
moles O = 5.09 g / (16 g /
mol) = 0.318 mol
The ratio becomes:
0.106 K: 0.106 Cl: 0.318 O
We divide all numbers with
the smallest number, in this case 0.106. This becomes:
K: Cl: 3O
Therefore the empirical formula
is:
