To illustrate the Lewis structure,
P has 5 valence electrons
O has 6 valence electrons (each for 4 oxygen)
And finally, for every negative charge, there is an additional valence electron
We should add these all up = 5 + 24 + 3 = 32 valence electrons
With this, we can be guided to illustrate the lewis structure as P as central atom and the 3 oxygen each with a single bond with P and 1 oxygen with a double bond with P. We place the valence electrons until octet rule is satisfied,
we will be left with 12 lone pairs for phosphate ion.
Answer:
So the answer to "every element and compound has a unique set of properties. True or False?" is TRUE
Explanation:
Answer: It releases energy that is called the fusion
Explanation: The reaction, which it is known as a nuclear fusion that converts hydrogen atoms into helium.
If the patient is given 150 mL/h of IV saline for 1.5 h 1.97 g NaCl she receive.
<h3>What is Molarity ?</h3>
Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar Concentration. The S.I unit of Molarity is molar (M) or mol/L.
It is expressed as:
Molarity (M) =
Molarity × Volume of solution = Number of moles
As we know that
Number of moles =
So,
Molarity × Volume of solution =
Molarity × Volume of solution × Molar Mass = Mass
Volume =
= 225 mL
Mass of NaCl = Molarity × Volume of solution × Molar Mass
= (0.15 mol/L NaCl) × (58.44 g/mol NaCl) × (225 ml × 0.001)
= 1.97 g NaCl
Thus from the above conclusion we can say that If the patient is given 150 mL/h of IV saline for 1.5 h 1.97 g NaCl she receive.
