I’m really sorry I need points I hope you find an answer
Explanation:
The given reaction equation is as follows.

So, rate constants for different reactants and products written as follows.

As per the reaction equation, the stoichiometric coefficients of reactants and products are as follows.
A = -2
B = -1
C = 1
Therefore,


Hence,
= 
= 12.5 
Thus, we can conclude that
and
are 12.5

Hello!
We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)
C: 83.7% = 83,7 g
H: 16.3% = 16.3 g
Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:


We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:


Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:

I hope this helps. =)
compressibility - is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. (D)
Flammability - ability of a chemical to burn or ignite, causing fire or combustion. (B)
Heat of Combustion - The amount of heat released per unit mass or unit volume of a substance when the substance is completely burned. (A)
Reactivity - the state or power of being reactive or the degree to which a thing is reactive (C)
Hope this helps!!
Answer:
Number of delocalized electrons
Explanation:
Magnesium has more delocalized electrons compared to sodium and this accounts for the higher melting point.
- When magnesium atoms comes together to form a metallic bonds, they have more network of delocalized electrons.
- There is more pull for the localized electrons due to the nuclear charge on the nucleus.
- This strong intermolecular metallic bond increases the melting point of magnesium.
