Answer:
Acceleration = 2.68 m/s² (Approx.)
Explanation:
Given:
Force = 792 mN = 0.792 N
Mass = 295,000 mg = 0.295 kg
Find:
Acceleration
Computation:
Acceleration = Force / mass
Acceleration = 0.792 / 0.295
Acceleration = 2.68 m/s² (Approx.)

What is the relationship between electrons and elements with
negative oxidation numbers? between electrons and elements
with positive oxidation numbers?
Explanation:
The higher its electronegativity, the more an element attracts electrons. The atom with higher electronegativity, typically a nonmetallic element, is assigned a negative oxidation number, while metallic elements are typically assigned positive oxidation numbers.... Hope it is useful brainliest plz if it was useful....
The relationship between electrons and oxidation number has bee the negative oxidation number implies the gain of the electron, while positive oxidation number implies the loss of electron by elements.
The oxidation number has been defined as the number of electrons lost or gained by an element to form a chemical bond. The elements that lose electrons are assigned positive oxidation number.
The elements that gain electrons to form a chemical bond are assigned a negative oxidation number.
The relationship between electrons and oxidation number has bee the negative oxidation number implies the gain of the electron, while positive oxidation number implies the loss of electron by elements.

Explanation:
How many moles of gas would occupy 22.4 L at 273K in one arm?
Answer:
1 mol
Explanation:
Using the general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the provided information in the question;
V = 22.4L
T = 273K
P = 1 atm
R = 0.0821 Latm/molK
n = ?
Using PV = nRT
n = PV/RT
n = (1 × 22.4) ÷ (0.0821 × 273)
n = 22.4 ÷ 22.4
n = 1mol

How many moles are in 5.30 X 1023 molecules of H2O?
Answer:
0.880 (0.88039867109 to be exact)
Explanation:
To convert from molecules to moles, simply divide by Avogadro's number which is 6.02 x 10^23
So, 5.30x10^23/6.02x10^23 = 0.880

What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Cells are made of many parts, or , that help the cell do its job. Each cell organelle has a specific function, or
Answer:
Organelles; role.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;
1. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.
2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.
3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Chromosomes : they give sets of instructions for the synthesis of products.
5. Ribosomes : they are involved in the build up of proteins.
6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.
7. Cytoskeleton : they help to maintain and support the shape of the cells.
8. Vesicles : they ensure proteins are properly transported to the right and exact location.
9. Golgi apparatus : it prepares the protein for export by chemically tagging them.
10. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
Hence, cells are made of many parts, or organelles, that help the cell do its job. Each cell organelle has a specific function, or role.

Look at this glass of soda. Use your knowledge of thermal energy transfer to explain how heat is affecting the following things: ice, soda, glass, and surrounding air.
Explanation:
Technically, the ice cube melts because the water cools down. This may sound ridiculous at first, but you must consider the fact that the ice melts because it has drawn "heat" (energy) from its surroundings. The "surroundings" being the air and water that surround it (but the water's more important since it's a better conductor of thermal energy).
The surrounding air looses energy while the ice in the glass gains energy.
We know that thermal energy is transferred from a hotter body to a cooler body. If we look as the glass, we will notice that the surrounding air has a greater energy compared to the contents of the glass. The surrounding air looses this energy resulting in the condensation of water vapor in air around the glass.
Similarly, the ice in the glass gains energy and melts. A change of state occurs from solid to liquid as a result of the energy absorbed from the surrounding air.
