The answer to is all the information on a line graph is as precise as the information in the data table would be FALSE
Explanation:
A synthesis reaction: It is defined as a kind of reaction where one and more than one reactant attached and creates an individual product.
The formation of the water is an example of a synthesis reaction because here more than one reactants combine and create a single product (water). Water formation occurs when 2 hydrogens and an oxygen share electrons through covalent bonds.
2H + O ----> H2O.
Answer:
a. -29.8 kJ/mol-rxn
Explanation:
For a chemical reaction system the forward and reverse rate are equal. The standard molar enthalpy formation of NH3 is -45.9 kJ/mol. For the enthalpy of NH3 (8) the molar enthalpy is -29.8kJ/mol. The molar mass of N2 = 28.02g/mol. Molar enthalpy of formation is standard amount of substance produced in the formation of a reaction. The molar enthalpy is the change in enthalpy due to reaction per mole.
Hi sweetie, hope this helps!
The more salt that is dissolved in the water, the less oxygen will be dissolved in it.
The higher the temperature of the water, the less oxygen will be dissolved it in.
Goodluck!,

Explanation:
A freezing point is defined as the point in which a liquid state of a substance changes into solid state.
Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.
So, a substance is freezing at
and boils at
then it means at room temperature, that is, around
the substance is present in liquid state.
This is because between the freezing and boiling point a substance will always exist in liquid state.
Thus, we can conclude that state of the material at room temperature is liquid.
