The balanced reaction is: H2O2 -> H2O + (1/2) O2
However, this is a very awkward equation since it has a
coefficient in fraction form.
Another way to write this equation is:
2 H2O2 -> 2 H2O + O2
Hope this helps.
Periods are subdivided into eras by geologists.
Properties of a compound is completely different from their elements.
Water is composed by hydrogen and oxygen.
For example, the boiling point of oxygen is - 183 °C and hydrogen is - 253 °C, meanwhile, water has a boiling point of 100°C
Another example is when you put a burning wooden splint into oxygen, it burns more brightly. Put it in hydrogen, you may hear a "pop" sound, or even explode when large amount of hydrogen. But if u put a burning splint in water, it goes off.
Answer:
<h3>Step 1: </h3>
To relate the volume and molarity of a solution at two different concentrations, the expression used is :
M₁V₁ = M₂V₂
<h3>
step 2:</h3>
(2M) V₁ = (0.15M)(250ML)
V₁ = 18.75
step 3:

If you’re given molecular weight, you know that density is mass/volume. You need to convert the molecular weight to volume. If you know what molecule it is, use the gram formula mass to convert it into grams.
