What is the mitochondia of the cell?

Chemistry
1 answer:
Gre4nikov [31]3 years ago
8 0

Answer:

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)

A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is 3.5 × 10-4 M in calcium ion and 2.33
Burka [1]

Answer:

B. A precipitate will form since Q > Ksp for calcium oxalate

Explanation:

Ksp of CaC₂O₄ is:

CaC₂O₄(s) ⇄ Ca²⁺ + C₂O₄²⁻

Where Ksp is defined as the product of concentrations of Ca²⁺ and C₂O₄²⁻ in equilibrium:

Ksp = [Ca²⁺][C₂O₄²⁻] = 2.27x10⁻⁹

In the solution, the concentration of calcium ion is 3.5x10⁻⁴M and concentration of oxalate ion is 2.33x10⁻⁴M.

Replacing in Ksp formula:

[3.5x10⁻⁴M][2.33x10⁻⁴M] = 8.155x10⁻⁸. This value is reaction quotient, Q.

If Q is higher than Ksp, the ions will produce the precipitate CaC₂O₄ until [Ca²⁺][C₂O₄²⁻] = Ksp.

Thus, right answer is:

<em>B. A precipitate will form since Q > Ksp for calcium oxalate</em>

1.5 moles of Al is how many<br> atoms?
aev [14]

Answer:

<h2>9.03 × 10²³ atoms </h2>

Explanation:

The number of atoms of Al can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 1.5 × 6.02 × 10²³

We have the final answer as

<h3>9.03 × 10²³ atoms</h3>

Hope this helps you

Calculate the density of a material that has a mass of 56.6 g and a volume of 17.2 cm
Cerrena [4.2K]

Answer:

d = 3.29 g/cm³

Explanation:

Given data:

Density of material = ?

Mass of material = 56.6 g

Volume of material = 17.2 cm³

Solution:

Formula;

d = m/v

d = density

m = mass

v = volume

by putting values,

d = 56.6 g/ 17.2 cm³

d = 3.29 g/cm³

alculate the molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution.
valentina_108 [34]

The molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.

<h3>What is Molarity? </h3>

Molarity is defined as the ratio of number of moles of solute to the volume of the solution.

Molarity = number of moles of solute/ Volume of solution

Given,

given mass of sodium hydroxide= 20 g

Volume of the solution = 200 mL.

Firstly, we will calculate the moles of sodium hydroxide.

<h3>What is Mole? </h3>

Mole is defined as the ratio of given mass of substance to the molar mass of substance.

Mole = given mass/ molar mass

Molar mass of sodium hydroxide = 40 g

Mole = 20/40

= 0.5 mol

Molarity = (0.5/ 200) × 1000 = 2.5M

Thus, we calculated that the molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.
