An oxygen atom is 16x more massive than a hydrogen atom.
You can figure this out by comparing the atomic masses of the two elements: oxygen has an atomic mass number of 16, and hydrogen has an atomic mass number of 1. Thus, an oxygen atom is 16 times more massive than a hydrogen atom.
Answer:
Benzene Hexachloride
Explanation:
BHC in benzene mean ''Benzene Hexachloride''.
<h2>B = Benzene</h2><h2>H + C = Hexachloride </h2>
As you can see, There are only two words and three letters. Even though it is one word, Hexa = H and Chloride = C
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
Answer: The two main factors that affect how viscous lava is are the mineral content of the lava and its temperature. Lava that contains more iron and magnesium, classifying it as basaltic or mafic, has a lower viscosity than lava that has more silicates and calcium, classifying that as rhyolitic or felsic. Additionally, lava at higher temperatures flows with less viscosity than lava at lower temperatures, especially when the temperature allows some of the minerals in the lava to crystallize.

A pH is an easy way to describe the acidity of a solution (determined by the [H+] concentration) - it’s easier to say that a cup of coffee has a pH of 5 rather than saying that the “hydrogen ion concentration is 10^-5 molar”.
The way pHs work is through logarithms, which convert a set of values into a new one using a base value. For example, pHs use a base 10 to simplify the numbers, while earthquake energy scales use a base of 32. An increase of 1 on the logarithmic scale is an “n” times increase in the scale, where “n” is the base of the logarithm. So, for example, in the case of pH, three solutions with a pH of 5, 6, and 7 can be related; the pH scale uses base ten, so the pH 6 solution is 10x more acidic than the pH 7, and the pH 5 is 100x (10x10) more acidic than the pH 7. For earthquakes, a magnitude 5 earthquake is 32x weaker than a magnitude 6 and 1,024x (32x32) weaker than a magnitude 7.
The pH formula looks like this:
pH = -log [H+]
The negative sign basically serves to make the low end acidic; without the negative, a pH of 14 would be extremely acidic instead of basic. It’s one of those things that you’ll just have to remember.
So, for your solution, just enter the concentration into the formula:
pH=-log[1.0 x 10^-4] = 4
The pH of this solution would be 4.
Hope this helps!
