Consider that a sample of a compound is decomposed and the masses of its constituent elements is as follows: 1.443 g Se, 0.5848

sladkih [1.3K]

Answer: The empirical formula is $SeO_2$ .

Explanation:

So, the mass of each element is given:

Mass of Se = 1.443 g

Mass of O = 0.5848 g

Step 1 : convert given masses into moles.

Moles of Se= $\frac{\text{ given mass of Se}}{\text{ molar mass of Se}}= \frac{1.443g}{79g/mole}=0.018moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{0.5848g}{16g/mole}=0.036moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Se = $\frac{0.018}{0.018}=1$

For O = $\frac{0.036}{0.018}=2$

The ratio of Se: O = 1: 2

Hence the empirical formula is $SeO_2$ .

Does moisture affect the length of time it takes for mold to grow on bread?

Pavlova-9 [17]

Answer:

it depends on the level of moisture of the bread wet bread molds more quickly than dry bread because mold thrives in damp environments if you didn't experiment and tested one slice of dry bread and one damp slice of the same bread the dampened slice would grow mold much more quickly than the dry one

I hope this helps have a good dày or night :)
