Neutral charges and are found in the center? I'm not sure for the last answer
The higher the greenhouse gases, the higher the ocean temperature
"The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures"
hope this helps :)
The Lewis formula refers to a diagram showing the distribution of electrones and in case of a molecule it also shows the bonds.
The structural formula on the other hand is a representation of the molecular structure that shows all the atoms that form the molecule, arranged in a three dimentional space,
In this case we have the hydrogen ion, which is the simpliest case we can have.
Hydrogen ion is the hydrogen atom possitively charged as it has lost his electron. Therefore the structural formula is simply the following:
The Lewis formula is also very simple as this ion has no electrons and has no bonding to other atoms:
Answer:
PbSO4 is not a covalent compound.
Explanation:
PbSO4 is an ionic compound.
PKa is defined as the logarithm of the inverse of Ka, i.e
pKa = log ( 1 / Ka)
Ka is the dissociation constant of the acid. The larger Ka the stronger the acid.
On the other hand, from pKa = log (1 / Ka) the larger Ka the smaller 1 /Ka, and so the smaller log (1/Ka).
So, the relation between Ka and pKa is inverse, which means that an acid with greater value of pKa will have lower value Ka, and so it will be weaker or the smaller the pKa the stronger the acid.
Therefore, in our case HA has the lower pKa ant it will be the stronger acid.
Answer: HA is the stronger acid, because it has the lower pKa and pKa is inversely related to the strength of the acid.
