Answer:

$Fe2O3 + 2Al \rightarrow 2Fe + Al2O3$

Explanation:

Hello!

In this case, when balancing chemical reactions, we must make sure that the atoms of each element are the same at both reactants and products; thus, for the given reaction, we need two iron and aluminum atoms at each side based on their subscripts in the given oxides as shown below:

$Fe2O3 + 2Al \rightarrow 2Fe + Al2O3$

Best regards!

AveGali [126]

$MgCO_3--^T-->MgO + CO_2\uparrow$

the oxidation number of carbon in MgCO3 = +IV
the oxidation number of carbon in CO2 = +IV

so, there is no change

Covert from scientific notation 1.3 x 10¹²=

Lady_Fox [76]

Answer:

1,300,000,000,000

Explanation:

1.3 x 10^12

We want to convert this from scientific notation.

Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000

So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.

1.3 x 10^12 ------> 1,300,000,000,000

Our answer is 1,300,000,000,000

Calculate the molar mass FeCl3 Fe2(SO4)3 PbO PbO2 Pb3O4

Anvisha [2.4K]

To find molar mass: look for each element on the table and find their atomic masses. Then add each atomic mass to find the molar mass. If there is a subscript then that means that there is 3 of that number. For atomic mass round to the nearest hundredths
FeCl3= 162.2
Fe2(SO4)3= 354.88
PbO=223.2
PbO2 = 239.2
Pb3O4=685.6
