For the reaction represented by the equation Fe + H2O ® Fe2O3 + H2, how many moles of iron(III) oxide are produced from 285 g of

schepotkina [342]

Balanced equation: 2Fe + 3H2O → Fe2O3 +3H2

Convert g to mols:

285/55.845 = 5.1034 mols

Mole ratio of Iron and Iron (III) Oxide: 2:1

5.1034/2 = 2.5517 mols

Calculate the atomic mass for copper using the weighted average mass method. Express your answer using two decimal places and in

tatuchka [14]

Answer:

63. 55 amu

Explanation:

Copper is known to exist in two different isotopes which are Cu-63 and Cu-65.

Cu-63 has an atomic mass of 62.93 amu and it has an abundance of 69.15%.

Similarly,

Cu-65 has an atomic mass of 64.93 amu and it has an abundance of 30.85%

Therefore, using the weighted average mass method, the atomic mass of copper is:

Atomic mass of copper = (0.6915*62.93) amu + (0.3085*64.93) amu = 43.52 amu + 20.03 amu = 63.55 amu

Thus, the atomic mass of copper (express in two decimal places) is 63.55 amu

HELP PLS !!!! :))Formula unit of Sr and CI<br><br> Formula unit of AI and S

xenn [34]

Answer : The formula unit of Sr & Cl is $SrCl_2$ and the formula unit of Al & S is $Al_2S_3$

Explanation :

Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.

For the formula unit of Sr & Cl, two chloride ions $(Cl^-)$ are needed to neutralize the one strontium ion $(Sr^{2+})$ .

For the formula unit of Al & S, three sulfide ions $(S^{2-})$ are needed to neutralize the two aluminium ion $(Al^{3+})$ .

The formula unit of $SrCl_2$ and $Al_2S_3$ are shown below.
