Answer:
Option 3. Specific heat capacity of the liquid
Explanation:
Let's think, the states for the substance.
In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.
We have to take from liquid state at 2°C to 155°C, which is the boiling point.
As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.
1. specific heat capacity of the solid → This is used, when the substance is solid.
2. Heat of fusion → Only used when you turn from liquid to solid
4. Heat of vaporization → Used when the substance changes its state from liquid to gas
5. specific heat capacity of the gas → Used when the substance is a gas.
Answer:
You can view more details on each measurement unit: molecular weight of NaCl or grams This compound is also known as Sodium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaCl, or 58.44277 grams.
The chemical formula is
FeF3
3 is a subscript
They are reactants. Reactants combined together in a chemical reaction to form products.
Answer:
The correct answer is:Oxygen is more electronegative than carbon. See the explanation below, please
Explanation:
The electronegativities of oxygen and carbon are: 3, 44 and 2, 55 respectively. The electronegativity is defined as the capacity that a given atom has for the attraction of electrons, by forming a chemical bond. Polarity is related to electronegativity. The greater the difference in electronegativities between two atoms, the polarity of the bond they form will be greater.
