Answer:
the one with less thermal energy
Explanation:
thermal energy is heat
Density = mass/volume
Therefore,
Density = 60g/30cm
Answer:
Heating the liquids and letting one boil away first :)
Explanation:
Answer:
109.09°C
Explanation:
Given that:
the capacity of the cooling car system = 5.6 gal
volume of solute = volume of the water; since a 50/50 blend of engine coolant and water (by volume) is used.
∴ 
Afterwards, the mass of the solute and the mass of the water can be determined as shown below:
mass of solute = 


On the other hand; the mass of water = 


Molarity = 
= 
= 17.757 m
≅ 17.76 m
∴ the boiling point of the solution is calculated using the boiling‑point elevation constant for water and the Molarity.

where,
= 0.512 °C/m
= 100°C + 17.56 × 0.512
= 109.09 °C
Answer:
A. The actual number of atoms in a molecule
Explanation:
Molecular formula is simply defined as a type of chemical formula that describes the type and number of atoms present in a single molecule of a compound.
Looking at the options, the correct answer is option A.
