The more acidic the substance is, the more the iron nails will corrode (this obviously depends on what your experiment is but hope this helped in some way)
Answer: The answer would be 85F
Explanation: The odour molecules become airborne much more quickly in a warmer environment than a colder one. So the bottle of perfume to spread faster through the air faster when the room temperature is 85F
The pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg
<h3>Pressure of gas collected over water</h3>
The total pressure of a gas collected over water is given by P = P' + p where
- P = pressure of oxygen gas and
- p = vapour pressure of water at 25 °C = 25 mmHg
Making P' subject of the formula, we have
P' = P - p
Since the total pressure of oxygen plus water vapor is P = 745.8 mmHg, substituting the values of the variables into the equation, we have
P' = P - p
P' = 745.8 mmHg - 25 mmHg
P' = 720.8 mmHg
So, the pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg

An Erlenmeyer flask is laboratory flask that has a conical shape and flat bottom with a tapered mouth. The Erlenmeyer flask is used for pouring, mixing and storing of chemicals in the laboratory. It was created by Emil Erlenmeyer in the 1860s.
A better explanation of these systems is given using molecular orbital theory.
<h3>What is the valence bond theory?</h3>
The valence bond theory hold that a bond is formed by the sharing of two electron in a covalent bond. This bond does not account for certain systems that occur in multiple bonded systems where the simple two electron bonding model does not suffice.
Thus, valence bond theory is inadequate for describing systems with multiple adjacent bonds that overlap, as in aromatic molecules. a better explanation of these systems is given using molecular orbital theory.
