<u>Answer:</u> The correct answer is Al_2O_3

<u>Explanation:</u>

Aluminium is the 13th element of the periodic table with electronic configuration of 1s^22s^22p^63s^23p^1

This element looses 3 electrons and shows an oxidation state of +3.

Oxygen is the 8th element of the periodic table with electronic configuration 1s^22s^22p^4

This element will gain 2 electrons and shows an oxidation state of -2.

By criss-cross method, the oxidation state of aluminium and oxygen gets revered and they form the coefficients of the compound.

Hence, the compound formed will have the chemical formula of Al_2O_3

Sediment layers stop lateral spreading when:
GREYUIT [131]
Sediment layers stop lateral spreading when they encounter a barrier and they run out of additional sedimentary material. Lateral spreading is the lateral movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. Hope this answers the question.

For the chemical reaction CaI2+2AgNO3-&gt; 2AgI+Ca(NO3)2 how many moles of silver iodide will be produced from 205g of calcium i
Colt1911 [192]

Answer:

Moles of silver iodide produced = 1.4 mol

Explanation:

Given data:

Mass of calcium iodide = 205 g

Moles of silver iodide produced = ?

Solution:

Chemical equation:

CaI₂ + 2AgNO₃     →      2AgI + Ca(NO₃)₂

Number of moles calcium iodide:

Number of moles = mass/ molar mass

Number of moles = 205 g/ 293.887 g/mol

Number of moles = 0.7 mol

Now we will compare the moles of calcium iodide with silver iodide.

                     CaI₂         :           AgI

                         1           :             2

                       0.7         :           2×0.7 = 1.4

Thus 1.4 moles of silver iodide will be formed from 205 g of calcium iodide.
