The compound methyl butanoate smells like apples. Its percent composition is 58.8% C, 9.9% H, and 31.4% O. What’s the empirical
blsea [12.9K]
To find the empirical formula you would first need to find the moles of each element:

58.8g/ 12.0g = 4.9 mol C

9.9g/ 1.0g = 9.9 mol H

31.4g/ 16.0g = 1.96 O

Then you divide by the smallest number of moles of each:

4.9/1.96 = 2.5

9.9/1.96 = 6

1.96/1.96 = 1

Since there is 2.5, you find the least number that makes each moles a whole number which is 2.

So the empirical formula is C5H12O2.

SnO2 + 2 H2 ——> Sn + 2 H2O
SpyIntel [72]

Answer:

0.15g

Explanation:

Given parameters:

Number of molecules of water = 1.2 x 10²¹ molecules

Unknown:

Mass of SnO₂  = ?

Solution:

To solve this problem, we have to work from the known to the unknown specie;

             SnO₂   +    2H₂    →   Sn  +   2H₂O

Ensure that the equation given is balanced;

       

Now,

          the known species is water;

                  6.02 x 10²³ molecules of water  = 1 mole

                   1.2 x 10²¹ molecules of water  = \frac{1.2 x 10^{21} }{6.02 x 10^{23} }    = 0.2 x 10⁻²moles

Number of moles of water  = 0.002moles

           From the balanced chemical equation:

         

             2 mole of water is produced from 1 mole of    SnO₂  

           0.002 moles of water will be produced from \frac{0.002}{2}  = 0.001moles

To find the mass;

           Mass  = number of moles x molar mass

Molar mass of  SnO₂ = 118.7 + 2(16) = 150.7g/mol

        Mass  =  0.001 x 150.7 = 0.15g

The development of new technology requires the evaluation of the overall benefit to cost ratio of the new technology.

Answer:

B and C Reduce Emissions and Least fuel economy

Explanation:

Plug-in electric vehicles are related, fun and practical (also called electric cars or hybrid electric vehicles).  We will reduce emissions and save you even money. EVs deliver more than individual advantages.  EVs will allow the US to have a more diverse range of transportation fuel options.  Last year the US used almost nine billion barrels of oil, of which two-thirds went into shipping.  We are vulnerable to price increases and supply disruptions because of our dependence upon oil. EVs help reduce this threat, as almost all US electricity, including coal, nuclear, natural gas and renewables, is generated from domestic sources.Vehicles can also minimize the CO2 emissions, improve health, and reduce environmental damage that contribute to climate change and smog. Charging your EV for renewable, such as solar or wind, will further reduce these emissions. Link to a calculator on the right to the pollution disparity between the traditional and an EV. Discover how EV reduce pollution and their emissions during their life cycle.
