<h2>What are the common Hazard and Risk?</h2>

hello there here is my answ

Physical hazards are environmental factors that can harm an employee without necessarily touching them, including heights, noise, radiation and pressure. Safety. These are hazards that create unsafe working conditions. For example, exposed wires or a damaged carpet might result in a tripping hazard

hope it helps

Answer:

A health hazard: Any organism, chemical, condition, or circumstance that may cause injury or illness.

A physical hazard is an agent, factor or circumstance that can cause harm with contact. They can be classified as type of occupational hazard or environmental hazard.

Risks:

Risk is the possibility of a harm arising from a particular exposure to a chemical substance, under specific conditions.

Crossing the street presents the hazard of getting hit by a passing car. But risk is the likelihood of harm actually occurring.

Analyze the diagram showing the changing states of matter. Drag the item from the item bank to its corresponding match.

iVinArrow [24]

The correct matches for changes of state are:

1 or 3 : Arrow that shows particles getting closer together
gas: State of matter that would fill any container
liquid: State of matter with definite volume but NOT shape
2 or 4: Arrow that shows particles gaining energy
solid: State of matter with definite shape

<h3>What is change of state?</h3>

Change of state is the process whereby matter in one physical state is converted to matter in another state by the addition or removal of heat.

The process of change of state are:

Melting: solid to liquid due to addition of heat
Vaporization: liquid to gas due to addition of heat
Sublimation: solid to gas due to addition of heat
Freezing: liquid to solid due to removal of heat
Condensation: gas to liquid due to removal of heat
Deposition: gas to solid due to removal of heat

Considering the given diagram, the correct matches are:

1 or 3 : Arrow that shows particles getting closer together
gas: State of matter that would fill any container
liquid: State of matter with definite volume but NOT shape
2 or 4: Arrow that shows particles gaining energy
solid: State of matter with definite shape

In conclusion, change of state of matter occurs due to heat changes.

Classify each of the following as a combination, decomposition, single replacement, double replacement, or combustion reaction:

hjlf

Answer:

1) single replacement

2) combustion reaction.

3) double replacement reaction

4) combination reaction

5) decomposition reaction

Explanation:

Chemical equation:

Fe₂CO₃ + 3C → 2Fe + 3CO

The given reaction is single replacement reaction. In this reaction carbon react with Fe₂CO₃ and replace the iron from CO₃²⁻ and form free iron and carbon monoxide.

Chemical equation:

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

The given reaction is combustion reaction. In which ethene burn in the presence of oxygen form carbon dioxide and water.

Chemical equation:

Fe₂O₃ + 6HCl → 2FeCl₃ + 3H₂O

The given reaction is double replacement reaction. In which anion and cation of both reactants exchange with each others.

Chemical equation:

2Al + 2Br₂ → 2AlBr₃

The given reaction is combination reaction in which aluminium and bromine combine to form aluminium bromide.

Chemical equation:

C₆H₁₂O₆ → 6C + 6H₂O

The given reaction is decomposition reaction in which glucose molecule decompose to give water and carbon.
