Here are my quick example slides:

1st Picture:
just a title page

2nd Picture:
I just gave the definition of an organelle you could go more in-depth. The picture doesn't have to be there, of course.

3rd Picture:
Examples of organelles in plant and animal cells, these are just examples of how I would do one.

This was just to show how you could do it because it would be kind of hard for me to explain just in words.

Hope I could help! c:

94.0 L if the reaction takes place under STP.

<h3>Explanation</h3>

The molar mass of glucose C₆H₁₂O₆ is

12.01 × 6 + 1.008 × 12 + 16.00 × 16.00 = 180.16 g / mol.

126 grams of glucose will contain 126 / 180.16 = 0.69939 mol of C₆H₁₂O₆. (To avoid rounding errors, keep a couple more digits than necessary.)

6 moles of CO₂ will be produced when 1 mole of C₆H₁₂O₆ is consumed. 0.69939 moles of C₆H₁₂O₆ will give rise to 4.196 mol of CO₂.

Assuming that the reaction takes place under STP, where T = 0 °C = 273 K and P = 1 atm. Each mole of any ideal gas will occupy a volume of 22.4 liters. The 4.196 moles of CO₂ will occupy 4.196 × 22.4 = 94.0 L. (The least significant number given is 126 g, the mass of glucose. This number has three significant figures. Thus, round the result to three significant figures.)

The volume of CO₂ can be found using the ideal gas law if the condition isn't STP. For example, T = 25 °C = 297 K and P = 1.00 × 10⁵ will lead to a different volume. By the ideal gas law,

V = (n · R · T) / (P)

where

V is the volume of the gas,
n is the number of moles of gas particles,
R is the ideal gas constant<em>,</em>
P is the pressure on the gas,
T is the absolute temperature of the gas (in degrees Kelvin.)

R = 8.314 × 10³ L · Pa / (K · mol)

Taking T = 297 K and P = 1.00 × 10⁵ Pa,

V = (4.196 × 8.314 × 10³ × 297 ) / (1.00 × 10⁵ ) = 104 L.

tankabanditka [31]

Answer:

0.108mol of Hydrogen

Explanation:

The formula for the compound is: CH3COOH

From the formula of the compound,

There are 2moles of oxygen and 4moles of Hydrogen.

If for every 2moles of oxygen, 4moles of Hydrogen is present.

Then, for 0.054 moles of oxygen = (0.054 x 4)/2 = 0.108mol of Hydrogen is present
