Draw the structure of tofacitinib with explicitly shown all carbon and hydogen atoms. identify the number of carbon atoms in tof
Andrew [12]

The structure of tofacitinib with explicit carbon and hydrogen is the first attached picture.

The number of carbon atoms in tofacitinib are 16.

The molecular formula of tofacitinib is C_{16}H_{20}N_{6}O.

The structure of tofacitinib with all the filled hydrogen atoms is the second attached picture.

The muscles on the run in transform chemical potential energy into_____
LekaFEV [45]

Mechanical Energy

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

Explanation:

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle.  The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.

This process is never 100% efficient with some energy lost as heat energy.

What mass (in grams) of silver contains the same number of atoms as 5.59 grams of sulfur?
Amanda [17]

Answer:

18.84 g of silver.

Explanation:

We'll begin by calculating the number atoms present in 5.59 g of sulphur. This can be obtained as follow:

From Avogadro's hypothesis,

1 mole of sulphur contains 6.02×10²³ atoms.

1 mole of sulphur = 32 g

Thus,

32 g of sulphur contains 6.02×10²³ atoms.

Therefore, 5.59 g of sulphur will contain = (5.59 × 6.02×10²³) / 32 = 1.05×10²³ atoms.

From the calculations made above, 5.59 g of sulphur contains 1.05×10²³ atoms.

Finally, we shall determine the mass of silver that contains 1.05×10²³ atoms.

This is illustrated below:

1 mole of silver = 6.02×10²³ atoms.

1 mole of silver = 108 g

108 g of silver contains 6.02×10²³ atoms.

Therefore, Xg of silver will contain 1.05×10²³ atoms i.e

Xg of silver = (108 × 1.05×10²³)/6.02×10²³

Xg of silver = 18.84 g

Thus, 18.84 g of silver contains the same number of atoms (i.e 1.05×10²³ atoms) as 5.59 g of sulfur
