The correct answer is A. molecular formula = 2 x empirical formula

The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.

¿Cuántos gramos de H2O habrá en 3,0115x1023 moléculas de agua?
jolli1 [7]

Answer : The weight of water is 9 g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

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

\text{Number of moles}=\frac{\text{Given molecules}}{\text{avogadro's number}}=\frac{3.0115\times 10^{23}}{6.023\times 10^{23}}=0.5moles


1 mole of water (H_2O) weighs = 18 g

0.5 moles of water(H_2O) weighs = \frac{18}{1}\times 0.5=9g

Thus the weight of water is 9 g

What are the similarities between the adrenal hormone cortisone and the synthetic corticoid prednisone?
vaieri [72.5K]

Answer:

Options a,b, c and d are correct

Explanation:

From the diagram attached in the picture below, They both have steroid nucleus since they have functional groups (such as the methyl and the ketone groups) that are spatially attached. It can also be deduced that both structures have three (3) ketone groups (CO/C=O), two (2) methyl groups (CH₃) and two (2) hydroxyl groups (OH). Hence, options a, b,c and d are correct.

However, cortisone has one (1) double bond while prednisone has two (2) double bonds.
