Be sure to answer all parts. the annual production of sulfur dioxide from burning coal and fossil fuels, auto exhaust, and other sources is about 26 million tons. the equation for the reaction is s(s) + o2(g) → so2(g) if 2.68 × 107 tons of sulfur dioxide formed, how many tons of sulfur were present in the original materials? assume 100% yield. × 10 tons enter your answer in scientific notation.

The amount of sulfur present in the original material is

Explanation:

Converting given amount of mass in tons to grams, we use the conversion factor:

1 ton = 907185 g            .......(1)

So,

To calculate the number of moles, we use the equation:

    ......(2)

Given mass of sulfur dioxide =

Molar mass of sulfur dioxide = 64 g/mol

Putting values in above equation, we get:

For the given chemical reaction:

By Stoichiometry of the reaction:

1 mole of sulfur dioxide is produced from 1 mole of sulfur

So, moles of sulfur dioxide will be produced from = moles of sulfur.

Now, calculating the mass of sulfur using equation 2:

Moles of sulfur =

Molar mass of sulfur = 32 g/mol

Putting values in equation 2, we get:

Converting this value in tons using conversion factor 1, we get:

Hence, the amount of sulfur present in the original material is

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
