Answer:
The pH would be 1.
Explanation:
The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.
Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.
By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
= 1
Answer:
Cold climates favor mechanical weathering.

I just took the test and this is the correct answer!
Answer:
E
Explanation:
A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap
Answer:
I think its 1, but im not too sure
The correct name of this isotope : Oxygen - 16
<h3>Further explanation</h3>
Given
Isotope : ₈¹⁶O
Required
The correct name
Solution
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In the following element notation,
X = symbol of elemental atom
A = mass number
Z = atomic number
The isotope name is usually followed by its mass number, so the symbol above can be expressed as oxygen - 16
