Answer : The correct option is 'X' (mitochondria).

Explanation :

In the given animal cell diagram,

W represent the vacuole.

X represent the mitochondria.

Y represent the nucleolus.

Z represent the cytoplasm.

The function of vacuole, it stores waste products and balance the pH level of the cell.

The function of mitochondria, most of the respiration reaction occurs in which carbon dioxide is produced by utilizing oxygen.

The function of nucleolus, it contains the hereditary information.

The function of cytoplasm, most of the chemical reaction occurs.

Therefore, the correct answer is 'X' (mitochondria).

Wine goes bad soon after opening because the ethanol in it reacts with oxygen gas from the air to form water and acetic acid , t
ryzh [129]

The mass of ethanol is consumed by the reaction of 3.37g oxygen gas is 4.85g

Explanation:

The balanced equation for the chemical reactions is;

CH₃CH₂OH + O₂ → CH₃COOH + H₂O

The mole ratio between oxygen and ethanol in the reaction is 1 : 1

The molar mass of O₂ is 32g / mole. Therefore the O₂ moles consumes in the reaction is;

3.37 / 32

If the molar mass of ethanol is 46.07g/mole, and the ration of reaction in 1 : 1; Then the moles of ethanol consumed is;

3.37/32 * 46.07

= 4.85g

Calculate the moles of 12.354 grams of c6h12o6
gavmur [86]

The correct answer is 0.06857 moles.

C₆H₁₂O₆, that is, glucose has six carbons, twelve hydrogens, and six oxygen atoms. The atomic weight of C, H and O are as follows:

Six atoms of carbon = 6 × 12.01 g = 72.06 g

Twelve atoms of hydrogen = 12 × 1.008 g = 12.096 g

Six atoms of oxygen = 6 × 16.00 g = 96.00 g

So, the molar mass of C₆H₁₂O₆ is 72.06 g + 12.096 g + 96.0 g = 180.156 g.

It can also be written in the form as 180.16 g of C₆H₁₂O₆ is equal to 1 mole of C₆H₁₂O₆or 180.16 g/mole (as the molar mass)

Now, there is a need to find moles of 12.354 grams of C₆H₁₂O₆. So, the final conversion is:

12.354 g C₆H₁₂O₆ × 1 mole of C₆H₁₂O₆ / 180.16 g C₆H₁₂O₆

= 0.06857 moles
