In the mitochondrion, small molecules combine withoxygen to produce water and carbon-di-oxide. This process releases a large amount of energy.
Explanation:
- The mitochondrial membrane is where the chemical processes happen, and where the fluid contains the matrix.
- It form an integral part of eukaryotic cells. Its principal function is to conduct cellular respiration. This implies that the cell sucks in nutrients, breaks it down and transforms it into energy.
- The oxygen present inside the cell is applied and mitochondria transform chemical energy from food in the cell into energy in a form that is accessible to the host cell, understood as oxidative phosphorylation, it occurs within mitochondria.
- The processes identified as the citric acid or Krebs cycle generate a chemical called NADH in the mitochondria matrix. NADH is then used to produce adenosine triphosphate (ATP) through enzymes located in the inner cone of the mitochondrial membrane.
- Within ATP the energy is contained within chemical bonds form. You can open those bonds and retrieve the energy.

Answer: 1.55 Jg°C
Explanation:
The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 943 joules
Mass of oil = 10g
C = ? (let unknown value be Z)
Φ = (Final temperature - Initial temperature)
= 89°C - 28°C = 61°C
Then, Q = MCΦ
943 J = 10g x Z x 61°C
943J = 610g°C x Z
Z = (943J / 610g°C)
Z = 1.55 Jg°C
Thus, the specific heat of the oil is 1.55 Jg°C

Mass is the quantity of matter present in a substance. The masses of the most abundant molecule of are 85.9325, 87.9296, and 89.9267 amu.
What are isotopes?
Isotopes are the elements of the same species with the same atomic number but differ in atomic mass and physical properties.
% abundance and mass of chlorine are:
Cl-35 = 34.9688 amu
Cl-37 = 36.9659 amu
% abundance and mass of oxygen are:
O-16 = 15.9949 amu
O-17 = 16.9991 amu
O-18 = 17.9991 amu
O -16 is the most abundant form of the oxygen isotope and Cl -35 of chlorine.
The masses of the most abundant molecule are given as:
Cl-35, Cl-35, O-16:
Cl-35, Cl-37, O-16:
Cl-37, Cl-37, O-16:
Therefore, 85.9325, 87.9296, and 89.9267 amu are the masses of the most abundant form of the molecule.

Chlorine has the following % abundance and mass:
Cl-35 = 75.76 %, 34.9688 amu
Cl-37 = 24.24 %, 36.9659 amu
Oxygen has the following % abundance and mass:
O-16 = 99.757 %, 15.9949 amu
O-17 = 0.038 %, 16.9991 amu
O-18 = 0.205 %, 17.9991 amu
Based in the % abundance O-16 is the most abundant oxygen isotope and Cl-35 is the most abundant chlorine isotope
So the most abundant molecule of Cl2O and their respective mass are as follows:
1) Cl-35, Cl-35, O-16
Mass = 34.9688 amu + 34.9688 amu + 15.9949 amu = 85.9325 amu
2) Cl-35, Cl-37, O-16
Mass = 34.9688 amu + 36.9659 amu + 15.9949 amu = 87.9296 amu
3) Cl-37, Cl-37, O-16
Mass = 36.9659 amu + 36.9659 amu + 15.9949 amu = 89.9267 amu

Given:
Flat rate = 5
Variable rate = 1.50
Option 1: Without discount
5 + 1.50x = 8.25
1.50x = 8.25 - 5
1.50x = 3.25
x = 3.25/1.5
x = 2.17 ⇒ 2 buckets
Option 2: with discount. $0.50 per bucket
5 + 0.50x = 8.25
0.50x = 8.25 - 5
0.50x = 3.25
x = 3.25/0.50
x = 6.50 buckets ⇒ 6 buckets.
Option 1: 2 buckets
Option 2: 6 buckets
Difference: 4 more buckets if she chose option 2. WITH DISCOUNT
flat rate = $5

Answer:
- The changed force of attraction between the two objects is 625 N.
Explanation:
The universal law of attraction states that the gravitational attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The mathematical expression is:
- F = G m₁ m₂ / d², where
- G is the gravitational constant,
- m₁ and m₂ are the respctive masses of the two objects, and
- d = distance between the two objects.
Then, if the masses m₁ and m₂ remain unchanged and the distance (on the denominator) is reduced by a factor of 5, the 1/d² = 1/(1/5)² = 5² = 25, which means that the force will be multiplied by 25.
So, 25 N × 25 = 625 N which is the changed force of attraction between them.
