3) molecular and structural
Explanation:
Molecular and structural are two terms that represents chemical formula of compounds and molecules.
The molecular formula shows the chemical symbols and the number of atoms combining using subscripts.
The structural formula gives the arrangement of elements in a compound and molecule using a diagrammatic approach.

Answer:
yes, Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4
Explanation:
If one of the parents have a genetic for a disease or illness, but one of them has a genetic for immunity for that disease then the offspring may be benefitted. ( Not 100% sure tho)
Elements are the simplest building blocks you can break matter down into using purely chemical methods. They are a pure substance made up from only one type of atom.
When you mix elements together these form compounds. The important difference is that as they are a mixture of more than one type of element, they CAN be broken down into more simple substances using chemical means!
As such Hydrogen or Oxygen cannot be simplified chemically (they are therefore elements), however dihydrogen monoxide (H2O or water) is a mixture of these elements that can be broken down using chemical means and so is a compound.
Answer:
393.1 KPa
Explanation:
Now we have to use the general gas equation;
P1V1/T1 = P2V2/T2
P1= initial pressure of the gas= 1.00atm
V1 = initial volume= 700.0 ml
T1= initial temperature= 0.0°C +273= 273K
V2= final volume= 200.0 ml
T2= final temperature =30.0°C +273= 303 K
P2= final pressure =????
Therefore;
P2= P1V1T2/ V2T1
P2= 1.00 × 700.0 × 303/ 200.0 × 273
P2= 3.88 atm
But
1 atm = 101.325 kilopascals
Therefore 3.88 atm = 3.88 × 101.325 kilopascals = 393.1 KPa
