d Burning a match is not a chemical reaction.
Answers
Answer:
I would say B
Explanation:
well the other options are wrong
Burning a match would be considered a chemical change because it forms new substances.
WHAT IS A CHEMICAL CHANGE:
A chemical change is a change that involves the chemical components of the substance involved leading to the formation of new substances. This is opposed to a physical change, which only involves a transformation of state. Examples of chemical changes include rusting, burning a match etc.Burning a match is an example of chemical change because it involves the formation of new substances such as ash, smoke etc from wood (match stick).Learn more: https://brainly.com/question/23693316?referrer=searchResults

Explanation:
Describe what happens to the arrangement and movement of particles when a substance boils.
Answers
Answer:
When boiling a substance, the particles obtain more kinetic and potential energy from the heat being delivered. The kinetic energy means that the particles starts moving more intensely, and the potential energy means that the particles start to move away further from each other, which means the substance expands in volume.
Explanation:
When a liquid is heated, the particles gain energy and begin to move faster and faster, expanding the liquid. As the liquid warms, the most energetic particles at the surface escape as vapor from the surface.
What are particles?A particle is a small localized object to which several physical or chemical properties, such as volume, density, or mass, can be assigned in the physical sciences.
Atoms are small units of matter that contain a number of particles known as subatomic particles. The term particle, on the other hand, refers to any small object.
As a result, the primary distinction between atoms and particles is that atoms are small units composed of multiple particles, whereas particles are minute portions of matter.
When a fluid is subjected to heat, the particles acquire energy and start moving extremely fast, causing the liquid to expand.
The much more energetic particles at the exterior getaway as vapor phase from the surface as the liquid warms.
Thus, the arrangement and movement of the particles gets disturbed when a substance is boiled, and it gets escaped as vapor.

is energy absorbed or released to separate the atoms in water molecules
Answers
Answer:
First of all, Energy is released when water molecules bond.
Explanation:
When a bond is formed its stability increases from their respective atoms. So energy is released but when we are breaking a bond we are changing a compound to a lower energy state to higher energy state it's stability decreases and requires a bit of extra energy higher stability of bond higher energy required to break it…

which one has minimum number of atom?
(a) 8g O2 gas
( b) 1g H gas
(c)7 g nitrogen gas
(d) 1.5 g helium gas
Answers
Answer: 1 g H2 gas
Explanation:
8g O2 = 0.25 moles
1g H2 = 0.50 moles [I assume you mean H2, not H. If it is H, then moles = 1.0 moles H
7g N2 = 0.25 moles
1.5 g He = 0.43 moles
===============
The moles above are based on molecules. All but He are multiplied by 2 to give the number of atoms. If H2 is correct, it has the greatest number of atoms. (Not if it is just H).
