The tractor trailer will push the car when they hit so therefore the car will have to greatest change
The statement that defines the specific heat capacity for a given sample is the quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.
<h3>What is specific heat capacity?</h3>
Specific heat capacity is the of heat to increase the temperature per unit mass.
The formula to calculate the specific heat is Q = mct.
The options are attached here:
- The temperature of a given sample is 1 %.
- The temperature that a given sample can withstand.
- The quantity of heat that is required to raise the sample's temperature by 1 °C1 °C (Kelvin).
- The quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.
Thus, the correct option is 4. The quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.

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.
