What gas is released during cellular respiration?

2 answers:

Carbon dioxide. <span>Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water. ATP, carbon dioxide, and water are all products of this process because they are what is created. Carbon dioxide is released as a gas when you exhale.</span>

If I use the dropper to add 10 mL of drink mix to 50 mL of water, what is the

Yuliya22 [10]

Answer:

16.7%

Explanation:

From the question given above, the following data were obtained:

Volume of drink mix = 10 mL

Volume of water = 50 mL

Percentage of drink mix =?

Next, we shall determine the total volume of the solution. This can be obtained as follow:

Volume of drink mix = 10 mL

Volume of water = 50 mL

Total volume of solution =?

Total volume of solution = (Volume of drink mix) + (Volume of water)

Total volume of solution = 10 + 50

Total volume of solution = 60 mL

Finally, we shall determine the percentage of the drink mix in the solution. This can be obtained as follow:

Volume of drink mix = 10 mL

Total volume of solution = 60 mL

Percentage of drink mix =?

Percentage of drink mix = Vol. of drink mix / total volume × 100

Percentage of drink mix = 10/60 × 100

Percentage of drink mix = 16.7%

If a sample of gas has a volume of 100.0ml when the pressure is 50.0kPa, what is volume when the pressure is increased to 400.0k

dalvyx [7]

Answer:

V₂ = 12.5 mL

Explanation:

Given data:

Initial volume = 100.0 mL

Initial pressure = 50.0 KPa

Final volume = ?

Final pressure = 400.0 KPa

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

50.0 KPa × 100.0 mL = 400 KPa × V₂

V₂ = 5000 KPa.mL/ 400 KPa

V₂ = 12.5 mL

explain why the properties of a reactant can be different from the properties off the products of the reaction

Mrac [35]

Answer:

The reactants and products in a chemical reaction contain the same atoms, but they are rearranged during the reaction. As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants.

7. predict how atoms such as c, h, o, and n share electrons in a covalent bond, the role of electronegativity, and the potential

Lena [83]

The atoms C,H,O and N becomes more electronegative as the periodic table's right side and top get increasingly electronegative as you move down it. A hydrogen bond needs to share elements with hydrogen in order to exist.

As you move up and to the right of the periodic table, the electronegative properties increase. To form a hydrogen bond, elements would have to be shared with hydrogen. Each element becomes increasingly electronegative as you move further right on the periodic table, with the exception of noble gases (which aren't particularly reactive).

In order to obtain stability, atoms C, H, O, and N would therefore most likely desire to share their electrons (i.e., they are more electronegative because they wish to "hog" electrons). Due to its intermediate electronegativity, hydrogen has a mid-range potential for forming bonds with other molecules.
