Answer:
what is the picture supposed to be?
Explanation:
Answer:
The answer to your question is; H2O and CO.
Explanation:
Ionic bonding is when a metal donates its valence electrons to a nonmetal.
Covalent bonding is when two nonmetals share electrons to reach noble gases' configuration.
NaF here we have a metal and a nonmetal, then the bonding is ionic.
MgO here, there is also a metal and a nonmetal, the bonding is ionic.
H2O here, there are two nonmetals, so this is a covalent bonding.
CO here, there are two nonmetals, the bonding is covalent.
Answer:
See explanation below
Explanation:
In order to calculate this, we need to use the following expression to get the concentration of the base:
MaVa = MbVb (1)
We already know the volume of NaOH used which is 13.4473 mL. We do not have the concentration of KHP, but we can use the moles. We have the mass of KHP which is 0.5053 g and the molecular formula. Let's calculate the molecular mass of KHP:
Atomic weights of the elements to be used:
K = 39.0983 g/mol; H = 1.0078 g/mol; C = 12.0107 g/mol; O = 15.999 g/mol
MM KHP = (1.0078*5) + (39.0983) + (8*12.0107) + (4*15.999) = 204.2189 g/mol
Now, let's calculate the mole of KHP:
moles = 0.5053 / 204.2189 = 0.00247 moles
With the moles, we also know that:
n = M*V (2)
Replacing in (1):
n = MbVb
Now, solving for Mb:
Mb = n/Vb (3)
Finally, replacing the data:
Mb = 0.00247 / (13.4473/1000)
Mb = 0.184 M
This would be the concentration of NaOH
An arrangement of electrons that tells us how many total electrons are in an atom or ion as well as the outermost is called Electronic configuration.
<h3>What is electronic configuration?</h3>
Electronic configuration is the arrangements of electrons in the orbitals of an atoms and this shows the total number of atoms present in the atoms orbits and it shows the different energy levels around an atomic nucleus.
Therefore, An arrangement of electrons that tells us how many total electrons are in an atom or ion as well as the outermost is called Electronic configuration.
